server: add warning log for missing admin secret

v2.10.0-beta.1

Introducing Apollo Federation v1 support (experimental)

HGE can now be used as a subgraph in an Apollo federated GraphQL server. You can read more about this feature in the RFC.

This is an experimental feature (can be enabled by setting HASURA_GRAPHQL_EXPERIMENTAL_FEATURES: apollo_federation). This is supported over all databases. To expose a table in an Apollo federated gateway, we need to enable Apollo federation in its metadata. This can be done via the *_track_table metadata API and console support will be added soon.

For example, given a table called user in a database which is not being tracked by Hasura, we can run *_track_table to enable Apollo federation for the table:

POST /v1/metadata HTTP/1.1
Content-Type: application/json
X-Hasura-Role: admin

{
  "type": "pg_track_table",
  "args": {
    "table": "user",
    "schema": "public",
    "apollo_federation_config": {
        "enable": "v1"
    }
  }
}

The above API call would add the @key directive in the GraphQL schema with fields argument set to the primary key of the table (say id), i.e:

type user @key(fields: "id") {
  id: Int!
  name: String
  ...
}

Behaviour changes

server: When providing a JSON path in a JWT claims map, you can now use double-quotes as well as single-quotes. Escaped characters in strings will now be honored appropriately, in the same way as JSON.
server: In certain error messages, JSON paths will use double-quotes instead of single-quotes to represent field access.

For example, instead of $.args['$set'], you will see $.args["$set"].

cli: Use 2-spaces indent for GraphQL content in metadata instead of tabs (#8469)

Example:

Old Behaviour metadata/query_collections.yml	New Behaviour metadata/query_collections.yml
- name: allowed-queries definition: queries: - name: getAlbums query: \| query getAlbums { albums { id title } }	- name: allowed-queries definition: queries: - name: getAlbums query: \| query getAlbums { albums { id title } }

Old Behaviour

metadata/query_collections.yml

New Behaviour

metadata/query_collections.yml

- name: allowed-queries
  definition:
    queries:
    - name: getAlbums
      query: |
      	query getAlbums {
      		albums {
      			id
      			title
      		}
      	}

- name: allowed-queries
  definition:
    queries:
    - name: getAlbums
      query: |
        query getAlbums {
          albums {
            id
            title
          }
        }

Update multiple records for Postgres

We are introducing a new way to allow updating multiple records in the same transaction for Postgres sources (#2768).

For example, the following query can be used to run the equivalent of two update_by_pk in a single transaction:

update_artist_many(
  updates: [
    { where: { id: { _eq: 1 } },
      _set: { name: "new name", description: "other" }
    }
    { where: { id: { _eq: 2 } },
      _set: { name: "new name" }
    }
    ]
) {
  affected_rows
  returning {
    name
  }
}

However, this feature allows arbitrary updates, even when they overlap:

update_artist_many(
  updates: [
    { where: { id: { _lte: 3 } },
      _set: { name: "first", description: "other" }
    }
    { where: { id: { _eq: 2 } },
      _set: { name: "second" }
    }
    { where: { id: { _gt: 2 } },
      _set: { name: "third", description: "hello" }
    }
    { where: { id: { _eq: 1 } },
      _set: { name: "done" }
    }
    ]
) {
  affected_rows
  returning {
    id
    name
  }
}

Given the table looked like this before the query:

id	name	description
1	one	d1
2	two	d2
3	three	d3
4	four	d4

After executing the query, the table will look like:

id	name	description
1	done	other
2	second	other
3	third	hello
4	third	hello

The returned data will look like this:

{
  "data": {
    "update_artist_many": [
      {
        "affected_rows": 3,
        "returning": [
          {
            "id": 1,
            "name": "first"
          },
          {
            "id": 2,
            "name": "first"
          },
          {
            "id": 3,
            "name": "first"
          }
        ]
      },
      {
        "affected_rows": 1,
        "returning": [
          {
            "id": 2,
            "name": "second"
          }
        ]
      },
      {
        "affected_rows": 2,
        "returning": [
          {
            "id": 3,
            "name": "third"
          },
          {
            "id": 4,
            "name": "third"
          }
        ]
      },
      {
        "affected_rows": 1,
        "returning": [
          {
            "id": 1,
            "name": "done"
          }
        ]
      }
    ]
  }
}

The way it works is:

we allow arbitrary where clauses (just like in a regular update)
we allow arbitrary updates (_set, _inc, etc., depending on the field type)
we run each update in sequence, in a transaction (if one of them fails, everything is rolled back)
we collect the return value of each query and return a list of results

server: Add support to customize the root field for streaming subscriptions (fixes #8618)

v2.8.3

Bug fixes and improvements

cli: fix performance regression with large metadata in metadata apply

During the execution of metadata apply command, the YAML metadata is converted into JSON format because the server API accepts metadata in JSON format. For large metadata(> ~20k LOC), due to a recent change this conversion was taking upwards of 2 minutes of time, increasing exponentially with metadata size. With the changes in this release, the performance regression has been fixed. Following is a benchmark comparison of time taken for YAML to JSON conversion before and after the changes for different metadata sizes:

Metadata size(LOC) Before(seconds) After(seconds)

10k 8.7 0.22

20k 15.9 0.29

50k 89.5 0.52

100k 271.9 0.81

300k - 2.3

Metadata size(LOC)	Before(seconds)	After(seconds)
10k	8.7	0.22

v2.8.0

Disabling query/subscription root fields

When a table is tracked in graphql-engine, three root fields are generated automatically namely <table>, <table>_by_pk and <table>_aggregate in the query and the subscription root. You can now control which root fields are exposed for a given role by specifying them in the select permission.

The main use-case for this feature is to disable APIs that access the table directly but which still need to be tracked so that:

It can be accessed via a relationship to another table
It can be used in select permissions for another table via a relationship

For such use-cases, we can disable all the root fields of the given table. This can be done by setting the select permission as follows:

{
   "role": "user",
   "permission": {
     "columns": [
       "id",
       "name"
     ],
     "filter": {},
     "allow_aggregations": true,
     "query_root_fields": [],
     "subscription_root_fields": []
   }
 }

Another use-case is to allow a role to directly access a table only if it has access to the primary key value. This can be done by setting the select permission as follows:

{
   "role": "user",
   "permission": {
     "columns": [
       "id",
       "name"
     ],
     "filter": {},
     "allow_aggregations": false,
     "query_root_fields": ["select_by_pk"],
     "subscription_root_fields": ["select_by_pk"]
   }
 }

Note that console support for this permission will be released later.

Introducing naming conventions (experimental)

Now, users can specify the naming convention of the auto-generated names in the HGE. This is an experimental feature (enabled by setting HASURA_GRAPHQL_EXPERIMENTAL_FEATURES: naming_convention) and is supported for postgres databases only for now. There are two naming conventions possible:

Naming Convention	Field names	Type names	Arguments	Enum values
`hasura-default`	Snake case	Snake case	Snake case	as defined
`graphql-default`	Camel case	Pascal case	Camel case	Uppercased

Suppose there is a table called my_table and it has columns id, date_of_birth, last_seen, then with graphql-default naming convention we will get the following auto-generated API:

query {
  myTable(orderBy: {dateOfBirth: asc}, limit: 10) {
    id
    dateOfBirth
    lastSeen
  }
}

To configure the naming convention for a source, set the naming convention in source customisation while adding the source:

{
  "resource_version": 2,
  "metadata": {
    "version": 1,
    "sources": [
      {
        "name": "default",
        "kind": "postgres",
        "tables": [],
        "configuration": {},
        "customization": {
          "naming_convention": "graphql-default"
        }
      }
    ]
  }
}

To set the default naming convention globally, use the environment variable HASURA_GRAPHQL_DEFAULT_NAMING_CONVENTION. Note that the global default can be overridden by the source customisation setting mentioned above.

Note: Custom field names and custom table names will override the naming convention (i.e. if the custom table name is my_table and naming_convention is graphql-default, the field names generated will be my_table, my_tableByPk, my_tableAggregate and so on).

Behaviour Changes

cli: change the ordering used for object fields in metadata files to alphabetical order

Example:

Server Metadata (JSON)	Old behaviour (YAML)	New Behaviour (YAML)
{ "function": { "schema": "public", "name": "search_albums" } }	function: schema: public name: search_albums	function: name: search_albums schema: public

v2.7.0

Streaming subscriptions

Streaming subscriptions can be used to subscribe only to the data which has been changed in the query. The streaming is done on the basis of a cursor, which is chosen by the user. See docs.

Request payload:

subscription GetUserLatestMessages ($user_id: uuid!) {
  messages_stream (
    cursor: {
      initial_value: {id: 0},
      ordering: ASC
    },
    batch_size: 1,
    where: {user_id: {_eq: $user_id}}
  ) {
    id
    message
  }
}

The above subscription streams the messages of the user corresponding to the user_id in batches of 1 message per batch.

Suppose there are two messages to be streamed, then the server will send two responses as following:

Response 1:

{
  "data": [
    {
      "id": 1,
      "message": "How are you!"
    }
  ]
}

Response 2:

{
  "data": [
    {
      "id": 5,
      "message": "I am fine"
    }
  ]
}

Announcing GraphQL Joins

We are delighted to announce Hasura’s data federation capabilities that accelerate the API development process by creating a single GraphQL schema from multiple data sources such as databases and remote GraphQL APIs. This allows you to query and mutate across federated data sources in real-time without writing any custom code. In addition, we can leverage many of Hasura’s powerful features from Hasura CE and Hasura Cloud. Hasura’s field level permissions for remote schemas applies for joins as well, allowing for tightly controlled data disclosure when federating sources. Leverage Hasura Cloud’s caching directive to instantly put caching in front of multiple remote GraphQL schemas.

Breaking changes

The query and raw-query field from http-logs for metadata requests are removed by default. Use HASURA_GRAPHQL_ENABLE_METADATA_QUERY_LOGGING to re-enable those fields.

Bug fixes and improvements

server: removed 'query' and 'raw-query' field from logs for metadata queries by default. Use HASURA_GRAPHQL_ENABLE_METADATA_QUERY_LOGGING to re enable those fields.

v2.5.0

Remote relationships from remote schemas

This release adds three new metadata API commands:

create_remote_schema_remote_relationship
update_remote_schema_remote_relationship
delete_remote_schema_remote_relationship

that allows to create remote relationships between remote schemas on the left-hand side and databases or remote schemas on the right-hand side. Both use the same syntax as remote relationships from databases:

type: create_remote_schema_remote_relationship
args:
  remote_schema: LeftHandSide
  type_name: LeftHandSideTypeName
  name: RelationshipName
  definition:
    to_remote_schema:
      remote_schema: RightHandSideSchema
      lhs_fields: [LHSJoinKeyName]
      remote_field:
        rhsFieldName:
          arguments:
            ids: $LHSJoinKeyName

type: create_remote_schema_remote_relationship
args:
  remote_schema: LeftHandSide
  type_name: LeftHandSideTypeName
  name: RelationshipName
  definition:
    to_source:
      source: RightHandSideSource
      table: {schema: public, name: RHSTable}
      relationship_type: object
      field_mapping:
        LHSJoinKeyName: RHSColumnName

Similarly to DB-to-DB relationships, only Postgres is supported on the right-hand side for now.

Deprecations

The custom_column_names property of TableConfig used on <db>_track_table and set_table_customization metadata APIs has been deprecated in favour of the new column_config property. custom_column_names will still work for now, however, values used in column_config will take precedence over values from custom_column_names and any overlapped values in custom_column_names will be discarded.

Behaviour Changes

cli: use indentation of 2 spaces in array elements of metadata YAML files

Example:

Old behaviour metadata/query_collections.yaml	New behaviour metadata/query_collections.yaml
- name: allowed-queries definition: queries: - name: getAlbums query: \| query getAlbums { albums { id title } }	- name: allowed-queries definition: queries: - name: getAlbums query: \| query getAlbums { albums { id title } }

Old behaviour

 metadata/query_collections.yaml

New behaviour

 metadata/query_collections.yaml

- name: allowed-queries
  definition:
    queries:
    - name: getAlbums
      query: |
        query getAlbums {
          albums {
            id
            title
          }
        }

- name: allowed-queries
  definition:
    queries:
      - name: getAlbums
        query: |
          query getAlbums {
            albums {
              id
              title
            }
          }

This change is a result of fixing some inconsistencies and edge cases in writing array elements. hasura metadata export will write YAML files in this format going forward. Also, note that this is a backwards compatible change.

cli: change ordering of elements in metadata files to match server metadata

Example:

Server Metadata (JSON)	Old behaviour (YAML)	New Behaviour (YAML)
{ "function": { "schema": "public", "name": "search_albums" } }	function: name: search_albums schema: public	function: schema: public name: search_albums

Streaming subscriptions

Streaming subscriptions can be used to subscribe only to the data which has been changed in the query. The streaming is done on the basis of a cursor, which is chosen by the user.

Request payload:

subscription GetUserLatestMessages ($user_id: uuid!) {
  messages_stream (cursor: {initial_value: {id: 0}, ordering: ASC}, batch_size: 1, where: {user_id: {_eq: $user_id}} ) {
    id
    from
    to
  }
}

The above subscription streams the messages of the user corresponding to the user_id in batches of 1 message per batch.

Suppose there are two messages to be streamed, then the server will send two responses as following:

Response 1:

{
  "data": [
    {
      "id": 1,
      "from": 155234,
      "to": 155523
    }
    ]
}

Response 2:

{
  "data": [
    {
      "id": 5,
      "from": 178234,
      "to": 187523
    }
    ]
}

v2.3.0

Experimental SQL optimizations

Row-level permissions are applied by a translation into SQL WHERE clauses. If some tables have similar row-level permission filters, then the generated SQL may be repetitive and not perform well, especially for GraphQL queries that make heavy use of relationships.

This version includes an experimental optimization for some SQL queries. It is expressly experimental, because of the security-sensitive nature of the transformation that it applies. You should scrutinize the optimized SQL generated by this feature before using it in production.

The optimization can be enabled using the --experimental-features=optimize_permission_filters flag or the HASURA_GRAPHQL_EXPERIMENTAL_FEATURES environment variable.

Breaking changes

Computed field comments are now used as the description for the field in the GraphQL schema. This means that computed fields where the comment has been set to empty string will cause the description of the field in the GraphQL schema to also be blank. Setting the computed field comment to null will restore the previous auto-generated description. The previous version of the Console would set the comment to empty string if the comment textbox was left blank, so some existing computed fields may unintentionally have empty string set as their comment.

v2.2.0

Nested Action Types

Actions now support nested responses as described by associated action types.Example:

type Product {
 id: bigint!
 name: String
}
type ElasticOutput {
 products: [Product!]!
 aggregations: jsonb
}

Previously, nested responses could be encapsulated in a generic "jsonb" output type but this loses precise type information for the API. The current support now allows specifying complex return types for the output.

Currently limits action relationships to top-level fields in the output types.

GraphQL REST Endpoints OpenAPI Body Specifications

GraphQL REST endpoints are documented via Swagger (OpenAPI) under the /api/swagger/json endpoint. We now document the request and response bodies of the endpoints in addition to previous information.

MS SQL Server Update for Hasura Server

Expand Transactions to GraphQL Queries and mssql_run-sql API

Extend transactions to GraphQL queries and mssql_run_sql API

Rollback a Transaction Based in the Transaction State

We can query the transaction state using XACT_STATE() scalar function. If the transaction is not active, don't rollback the transaction.

Upsert - SQL Generation and Execution

We are translating the if_matched section from the graphql, which is represented by the if_matched type, to a MERGE SQL statement. Example:

mutation {
  insert_author(
    objects: { id: 1, name: "aaa" }
    if_matched: { match_columns: author_pkey, update_columns: name }
  ) {
    returning {
      id
      name
    }
  }
}

Breaking Changes

For any MSSQL backend, count aggregate query on multiple columns is restricted with a GraphQL schema change as follows

count (
---  columns: [table_select_column!]
+++  column: table_select_column
  distinct: Boolean
): Int!

MSSQL doesn't support applying COUNT() on multiple columns.

v2.1.0-beta.2

Action transforms

Action transforms are used to perform transformations on the HTTP request generated by an action. This allows you to integrate REST APIs or existing APIs without writing a middleware service that transforms the action's request to the one expected by the API.

Function field names customization (#7405)

It is now possible to specify the GraphQL names of tracked SQL functions in Postgres sources, and different names may be given to the _aggregate and suffix-less versions. Aliases may be set by both /v1/metadata/pg_track_function and the new API endpoint /v1/metadata/pg_set_function_customization.

Root field name and type name customization per source (#6974)

When adding a source it is now possible to specify prefixes and suffixes that will be added to all root field names and type names generated for that source. It is also possible to specify a root "namespace" field to use for the source.

v2.0.0-alpha.9

We now support comparing columns across related tables. For example:

Consider two tables, items(id, name, quantity) and shopping_cart(id, item_id, quantity) and these two tables are related via the item_id column. Now, while defining insert permission on the shopping_cart table, there can be a check to insert an item into the shopping cart only when there are enough present in the items inventory.

v2.0.0-alpha.8

Support for 3D PostGIS Operators

We now support the use of the functions ST_3DDWithin and ST_3DIntersects in boolean expressions. Note that ST_3DIntersects requires PostGIS be built with SFCGAL support which may depend on the PostGIS distribution used.

Support for null values in boolean expressions

In v2, we introduced a breaking change, that aimed at fixing a long-standing issue: a null value in a boolean expression would always evaluate to True for all rows. For example, the following queries were all equivalent:

delete_users(where: {_id: {_eq: null}})  # field is null, which is as if it were omitted
delete_users(where: {_id: {}})           # object is empty, evaluates to True for all rows
delete_users(where: {})                  # object is empty, evaluates to True for all rows
delete_users()                           # delete all users

This behaviour was unintuitive, and could be an unpleasant surprise for users that expected the first query to mean "delete all users for whom the id column is null". Therefore in v2, we changed the implementation of boolean operators to reject null values, as we deemed it safer:

delete_users(where: {_id: {_eq: null}})  # error: argument of _eq cannot be null

However, this change broke the workflows of some of our users who were relying on this property of boolean operators. This was used, for instance, to conditionally enable a test:

query($isVerified: Boolean) {
  users(where: {_isVerified: {_eq: $isVerified}}) {
    name
  }
}

In the future, we will probably offer a way to explicitly choose which behaviour to use for each where clause; perhaps by introducing new and distinct operators that make it explicit that they will default to true if the value is null. In the meantime, this release provides a way to revert the engine to its previous behaviour: if the HASURA_GRAPHQL_V1_BOOLEAN_NULL_COLLAPSE environment variable is set to "true", null values in boolean expression will behave like they did in v1 for the following operators: _is_null, _eq, _neq, _in, _nin, _gt, _lt, _gte, _lte.

v2.0.0-alpha.7

Transactions for Postgres mutations

With v2 came the introduction of heterogeneous execution: in one query or mutation, you can target different sources: it is possible, for instance, in one mutation, to both insert a row in a table in a table on Postgres and another row in another table on MSSQL:

mutation {
  // goes to Postgres
  insert_author_one(object: {name: "Simon Peyton Jones"}) {
    name
  }

  // goes to MSSQL
  insert_publication_one(object: {name: "Template meta-programming for Haskell"}) {
    name
  }
}

However, heterogeneous execution has a cost: we can no longer run mutations as a transaction, given that each part may target a different database. This is a regression compared to v1.

While we want to fix this by offering, in the future, an explicit API that allows our users to choose when a series of mutations are executed as a transaction, for now we are introducing the following optimisation: when all the fields in a mutation target the same Postgres source, we will run them as a transaction like we would have in v1.

v2.0.0-alpha.6

Support geometry and geography spatial data comparison operators in MS SQL Server

Comparison operators on spatial data types, geometry and geography, are now supported in MS SQL Server. The following operators are supported:

STEquals
STIntersects
STTouches
STOverlaps
STCrosses
STWithin
STContains

Example query: Select values equal to a given geography instance

query {
  spatial_types_geog(
    where: {
      point: { _st_equals: "POINT(3 4)" }
      }
    ) {
    point
  }
}

Example query: Select values that spatially contain a given geometry instance

query {
  spatial_types_geom(
    where: {
      compoundcurve: { _st_contains: "POINT(0.5 0)" }
    }

v1.4.0-alpha.1

REST Endpoints

The RESTified GraphQL Endpoints API allows for the use of a REST interface to saved GraphQL queries and mutations.

Users specify the query or mutation they wish to make available, as well a URL template. Segments of the URL template can potentially capture data to be used as GraphQL variables.

See the documentation at graphql/core/api-reference/restified for more information.

Heterogeneous execution

Previous releases have allowed queries to request data from either Postgres or remote schemas, but not both. This release removes that restriction, so multiple data sources may be mixed within a single query. For example, GraphQL Engine can execute a query like

query {
  articles {
    title
  }
  weather {
    temperature
  }
}

where the articles are fetched from the database, and the weather is fetched from a remote server.

Support tracking VOLATILE SQL functions as mutations. (closing #1514)

Previously we could only track STABLE or IMMUTABLE functions, and only as queries. Now the version 2 of track_table also supports tracking functions as mutations:

  {
    "type": "track_function",
    "version": 2,
    "args": {
        "function": {
            "schema": "public",
            "name": "some_volatile_function"
        },
        "configuration": {
            "exposed_as": "mutation"
        }
      }
    }

Remote schema permissions

Now, permissions can be configured for remote schemas as well, which works similar to the permissions system of the postgres tables. Fields/arguments can be removed from the schema and arguments can also be preset to limit the role from having unrestricted access over it.

NOTE: To enable remote schema permissions, the graphql-engine needs to be started either with the server flag --enable-remote-schema-permissions or the environment variable HASURA_GRAPHQL_ENABLE_REMOTE_SCHEMA_PERMISSIONS set to true.

Function Permissions

Before volatile functions were supported, the permissions for functions were automatically inferred from the select permission of the target table. Now, since volatile functions are supported we can't do this anymore, so function permissions are introduced which will explicitly grant permission to a function for a given role. A pre-requisite to adding a function permission is that the role should have select permissions to the target table of the function.

`ltree` comparison operators

Comparison operators on columns with ltree, lquery or ltxtquery types are now supported, for searching through data stored in a hierarchical tree-like structure.

See the documentation at graphql/core/queries/query-filters more details on the currently supported ltree operators.

Example query: Select ancestors of an ltree argument

query {
  tree (
    where: {path: {_ancestor: "Tree.Collections.Pictures.Astronomy.Astronauts"}}
  ) {
    path
  }
}

Example response:

{
  "data": {
    "tree": [
      {
        "path": "Tree"
      },
      {
        "path": "Tree.Collections"
      },
      {
        "path": "Tree.Collections.Pictures"
      },
      {
        "path": "Tree.Collections.Pictures.Astronomy"
      },
      {
        "path": "Tree.Collections.Pictures.Astronomy.Astronauts"
      }
    ]
  }
}

Breaking changes

This release contains the PDV refactor (#4111), a significant rewrite of the internals of the server, which did include some breaking changes:
- The semantics of explicit null values in where filters have changed according to the discussion in issue 704: an explicit null value in a comparison input object will be treated as an error rather than resulting in the expression being evaluated to True. For instance: delete_users(where: {id: {_eq: $userId}}) { name } will yield an error if $userId is null instead of deleting all users.
- The validation of required headers has been fixed (closing #14 and #3659):
  - if a query selects table bar through table foo via a relationship, the required permissions headers will be the union of the required headers of table foo and table bar (we used to only check the headers of the root table);
  - if an insert does not have an on_conflict clause, it will not require the update permissions headers.
This release contains the remote schema permissions feature, which introduces a breaking change:

Earlier, remote schemas were considered to be a public entity and all the roles had unrestricted access to the remote schema. If remote schema permissions are enabled in the graphql-engine, a given remote schema will only be accessible to a role ,if the role has permissions configured for the said remote schema and be accessible according to the permissions that were configured for the role.

v1.3.3

Server - Support for mapping session variables to default JWT claims

Some auth providers do not let users add custom claims in JWT. In such cases, the server can take a JWT configuration option called claims_map to specify a mapping of Hasura session variables to values in existing claims via JSONPath or literal values.

Example:-

Consider the following JWT claim:

  {
    "sub": "1234567890",
    "name": "John Doe",
    "admin": true,
    "iat": 1516239022,
    "user": {
      "id": "ujdh739kd",
      "appRoles": ["user", "editor"]
    }
  }

The corresponding JWT config can be:

  {
    "type":"RS512",
    "key": "<The public Key>",
    "claims_map": {
      "x-hasura-allowed-roles": {"path":"$.user.appRoles"},
      "x-hasura-default-role": {"path":"$.user.appRoles[0]","default":"user"},
      "x-hasura-user-id": {"path":"$.user.id"}
    }
  }

Metadata Types SDK

The types and documentation comments for Metadata V2 have been converted into JSON/YAML Schema, and used to autogenerate type definitions for popular languages.

This enables users to build type-safe tooling in the language of their choice around Metadata interactions and automations.

Additionally, the JSON/YAML Schemas can be used to provide IntelliSense and autocomplete + documentation when interacting with Metadata YAML/JSON files.

For a more comprehensive overview, please see the readme located here

Sample Code

import { TableEntry } from "../generated/HasuraMetadataV2";

const newTable: TableEntry = {
  table: { schema: "public", name: "user" },
  select_permissions: [
    {
      role: "user",
      permission: {
        limit: 100,
        allow_aggregations: false,
        columns: ["id", "name", "etc"],
        computed_fields: ["my_computed_field"],
        filter: {
          id: { _eq: "X-Hasura-User-ID" },
        },
      },
    },
  ],
};

Breaking changes

PDV

This release contains the PDV refactor (#4111), a significant rewrite of the internals of the server, which did include some breaking changes:

The semantics of explicit null values in where filters have changed according to the discussion in issue 704: an explicit null value in a comparison input object will be treated as an error rather than resulting in the expression being evaluated to True. For instance: delete_users(where: {id: {_eq: $userId}}) { name } will yield an error if $userId is null instead of deleting all users.
The validation of required headers has been fixed (closing #14 and #3659):
- if a query selects table bar through table foo via a relationship, the required permissions headers will be the union of the required headers of table foo and table bar (we used to only check the headers of the root table);
- if an insert does not have an on_conflict clause, it will not require the update permissions headers.

Remote Relationship

In this release, a breaking change has been introduced:

In a remote relationship query, the remote schema will be queried when all of the joining arguments are not null values. When there are null value(s), the remote schema won't be queried and the response of the remote relationship field will be null. Earlier, the remote schema was queried with the null value arguments and the response depended upon how the remote schema handled the null arguments.

Relay

The Hasura GraphQL Engine serves Relay schema for Postgres tables which has a primary key defined.

The Relay schema can be accessed through /v1beta1/relay endpoint.

[Add docs links][add console screenshot for relay toggle]

Remote Joins

Remote Joins extend the concept of joining data across tables, to being able to join data across tables and remote schemas.

It works similar to table relationships. Head to the Relationship tab in your table page and define a remote relationship:

give a name for the relationship
select the remote schema
give the join configuration from table columns to remote schema fields.

[Add docs links][add console screenshot]

Scheduled Triggers

A scheduled trigger can be used to execute custom business logic based on time. There are two types of timing events: cron based or timestamp based.

A cron trigger will be useful when something needs to be done periodically. For example, you can create a cron trigger to generate an end-of-day sales report every weekday at 9pm.

You can also schedule one-off events based on a timestamp. For example, a new scheduled event can be created for 2 weeks from when a user signs up to send them an email about their experience.

(close #1914)

Allow access to session variables by computed fields (fix #3846)

Sometimes it is useful for computed fields to have access to the Hasura session variables directly. For example, suppose you want to fetch some articles but also get related user info, say likedByMe. Now, you can define a function like:

CREATE OR REPLACE FUNCTION article_liked(article_row article, hasura_session json)
RETURNS boolean AS $$
  SELECT EXISTS (
    SELECT 1
    FROM liked_article A
    WHERE A.user_id = hasura_session ->> 'x-hasura-user-id' AND A.article_id = article_row.id
  );
$$ LANGUAGE sql STABLE;

and make a query like:

query {
  articles {
    title
    content
    likedByMe
  }
}

Support for this is now added through the add_computed_field API.

Read more about the session argument for computed fields in the docs.

Manage seed migrations as SQL files

A new seeds command is introduced in CLI, this will allow managing seed migrations as SQL files

Creating seed

# create a new seed file and use editor to add SQL content
hasura seed create new_table_seed

# create a new seed by exporting data from tables already present in the database
hasura seed create table1_seed --from-table table1

# create from data in multiple tables:
hasura seed create tables_seed --from-table table1 --from-table table2

Applying seed

# apply all seeds on the database:
hasura seed apply

# apply only a particular seed
hasura seed apply --file 1234_add_some_seed_data.sql

Include the changelog from v1.2.0-beta.1, v1.2.0-beta.2, v1.2.0-beta.3, v1.2.0-beta.4, v1.2.0-beta.5

Additional changelog:

CLI: Support servers with self-signed certificates (close #4564) (#4582)

A new flag --certificate-authority is added so that the CA certificate can be provided to trust the Hasura Endpoint with a self-signed SSL certificate.

Another flag --insecure-skip-tls-verification is added to skip verifying the certificate in case you don't have access to the CA certificate. As the name suggests, using this flag is insecure since verification is not carried out.

`v1.2.0-beta.5`

server: backend only insert permissions

Introduces optional backend_only (default: false) configuration in insert permissions (see api reference). If this is set to true, the insert mutation is accessible to the role only if the request is accompanied by x-hasura-use-backend-only-permissions session variable whose value is set to true along with the x-hasura-admin-secret header. Otherwise, the behavior of the permission remains unchanged.

This feature is highly useful in disabling insert_table mutation for a role from frontend clients while still being able to access it from a Action webhook handler (with the same role).

(rfc #4120) (#4224)

server: debugging mode for non-admin roles

For any errors the server sends extra information in extensions field under internal key. Till now this was only available for admin role requests. To enable this for other roles, start the server with --dev-mode flag or set HASURA_GRAPHQL_DEV_MODE env variable to true:

$ graphql-engine --database-url <database-url> serve --dev-mode

In case you want to disable internal field for admin role requests, set --admin-internal-errors option to false or or set HASURA_GRAPHQL_ADMIN_INTERNAL_ERRORS env variable to false

$ graphql-engine --database-url <database-url> serve --admin-internal-errors false

This feature come in handy during development when you may want to see detailed errors irrespective of roles.

Improved internal errors for Actions:

(This is a breaking change with previous 1.2.0-beta releases)

The internal field for action errors is improved with more debug information. It now includes request, response and error fields instead of just webhook_response field.

Before:

{
  "errors": [
    {
      "extensions": {
        "internal": {
          "webhook_response": {
            "age": 25,
            "name": "Alice",
            "id": "some-id"
          }
        },
        "path": "$",
        "code": "unexpected"
      },
      "message": "unexpected fields in webhook response: age"
    }
  ]
}

After:

{
  "errors": [
    {
      "extensions": {
        "internal": {
          "error": "unexpected response",
          "response": {
            "status": 200,
            "body": {
              "age": 25,

            },
            "headers": [

        "code": "unexpected"
      },
      "message": "unexpected fields in webhook response: age"
    }
  ]
}

cli: add support for .env file

ENV vars can now be read from .env file present at the project root directory. A global flag, --envfile, is added so you can explicitly provide the .env filename, which defaults to .env filename if no flag is provided.

Example:

hasura console --envfile production.env

The above command will read ENV vars from production.env file present at the project root directory.

(close #4129) (#4454)

console: allow setting post-update check in update permissions

(close #4142) (#4313)

console: support for Postgres materialized views

Postgres materialized views are views that are persisted in a table-like form. They are now supported in the Hasura Console, in the same way as views. They will appear on the 'Schema' page, under the 'Data' tab, in the 'Untracked tables or views' section.

console: manage Postgres check constraints

Postgres Check constraints allows you to specify that the value in a certain column must satisfy a Boolean (truth-value) expression. They can be used to put in simple input validations for mutations and with this release, these constraints can now be added while creating a table or later from Modify tab on the console.

Example: When a product is created, ensure that the price is greater than zero. The SQL would look like this:

CREATE TABLE products (
    product_id UUID DEFAULT gen_random_uuid(),
    name TEXT,
    price NUMERIC CONSTRAINT positive_price CHECK (price > 0)
);

To create this table with Hasura Console, on the 'Add a new table' screen, after adding all the columns, scroll down to 'Check constraints' section and 'Add a new check constraint' with the following properties:

Constraint name: positive_price
Check expression: price > 0

Read more about check constraints on Postgres Docs.

CLI: V2 migrations architecture

A new CLI migrations image is introduced to account for the new migrations workflow. If you're have a project with version: 2 in config.yaml, you should use the new image: hasura/graphql-engine:v1.2.0-cli-migrations-v2. Mount the migrations at /hasura-migrations and metadata at /hasura-metadata.

See upgrade docs.

`v1.2.0-beta.1`

Hasura Actions

Actions are a way to extend Hasura’s auto-generated mutations with entirely custom ones which can handle various use cases such as data validation, data enrichment from external sources and any other complex business logic.

A new mutation can be created either by defining its GraphQL SDL or by deriving it from an existing Hasura-generated mutation. The resolver is exposed to Hasura as a webhook which can be called synchronously or asynchronously. This release also includes an ever evolving codegen workflow to make managing the custom resolvers easier.

Downgrade command

A new command is added to the server executable for downgrading to earlier releases. Previously, if you ran a newer Hasura version and wanted to go back to an old version on the same database, you had to stop Hasura, run some SQL statements and start Hasura again. With the new downgrade command, these SQL statements can be run automatically.

Example: Downgrade from v1.2.0 to v1.0.0:

# stop hasura v1.2.0

# run the following command:
docker run hasura/graphql-engine:v1.2.0 graphql-engine --database-url <db-url> downgrade --to-v1.0.0

# start hasura v1.0.0

Read more about this command in the docs.

Expiration of connections authenticated by WebHooks

When using webhooks to authenticate incoming requests to the GraphQL engine server, it is now possible to specify an expiration time; the connection to the server will be automatically closed if it's still running when the expiration delay is expired.
