# Firebase Auth + Hasura JWT
Barebones example to show how to have Firebase Auth integrated with Hasura JWT mode.
## Firebase Auth
Firebase has few ways of implementing custom JWT claims in Firebase Auth:
1. Have firebase generate the JWTs, then customize them from your backend using
Firebase Admin SDK [[docs]](https://firebase.google.com/docs/auth/admin/custom-claims#defining_roles_via_an_http_request)
2. Use Firebase cloud functions, and listen to user creation events to add
custom claims to generated JWT [[docs]](https://firebase.google.com/docs/auth/admin/custom-claims#defining_roles_via_firebase_functions_on_user_creation)
3. Have your own backend server, which generates custom tokens [[docs]](https://firebase.google.com/docs/auth/admin/create-custom-tokens)
4. Have your own backend scripts (not initiated by the client) to update user custom claims [[docs]](https://firebase.google.com/docs/auth/admin/custom-claims#defining_roles_via_backend_script)
## Add custom claims in Firebase
In this example, we are choosing the option 2 from above. But this can be done via any of the above methods. [Firebase docs](https://firebase.google.com/docs/auth/admin/custom-claims) have extensive documentation on how to achieve this via different methods.
This example is adapted from [this guide](https://firebase.google.com/docs/auth/admin/custom-claims#defining_roles_via_firebase_functions_on_user_creation).
### Pre-requisites
This example assumes that you already have Firebase Auth setup for your app.
### Add the cloud function
Deploy the cloud function inside `functions/` folder:
```shell
firebase deploy --only functions
```
Customize the code to add your logic of assigning roles in the custom claims.
This cloud function is using the `onCreate` trigger. So whenever a user is created, this function is run.
### Client-side code
The client-side code is in `app/` folder.
## Configure Hasura to start in JWT mode
- Deploy GraphQL Engine on Hasura Cloud and setup PostgreSQL via Heroku:
[![Deploy to Hasura Cloud](https://graphql-engine-cdn.hasura.io/img/deploy_to_hasura.png)](https://cloud.hasura.io/signup)
After deploying, add the following environment variables to configure JWT mode:
```
HASURA_GRAPHQL_ADMIN_SECRET : youradminsecretkey
```
```
HASURA_GRAPHQL_JWT_SECRET: {"type":"RS256", "jwk_url": "https://www.googleapis.com/service_accounts/v1/jwk/securetoken@system.gserviceaccount.com", "audience": "<firebase-project-id>", "issuer": "https://securetoken.google.com/<firebase-project-id>"}
```
## Sending JWT to Hasura
Now, whenever you make a request to Hasura GraphQL engine (as an authenticated user), send the `id_token` in `Authorization` header:
```
Authorization: Bearer <firebase-id-token>
```

# gatsby-contentful-auth0
This is the sample music playlist application demonstrating the Gatsby + Contentful Remote Join with Hasura GraphQL.
## Getting started
If you've cloned this repository, navigate into the directory and install the npm modules using this command:
```bash
npm install
```
> Note: if you clone this project through the Gatsby CLI, it will install the modules for you.
## Auth0
This application uses Auth0 to manage identity. Refer to the [Auth0 integration guide](https://hasura.io/docs/latest/graphql/core/guides/integrations/auth0-jwt.html) for the configuration.
### Modify auth config
Rename `.env.EXAMPLE` to `.env.development` (or `.env.production`) and replace `<value>` for `AUTH0_DOMAIN` and `AUTH0_CLIENTID` with your Auth0 domain prefix and your client ID. These can be found on your [client dashboard](https://manage.auth0.com/#/clients).
Replace the `<value>` for `AUTH0_CALLBACK` with the URL for your callback route. The default for development is `http://localhost:8000/callback`.
## Contentful
Contentful remote schema is added as part of the migration. Configure the environment variables in Hasura GraphQL Engine server for the types to get merged.
- `CONTENTFUL_API_KEY`
- `CONTENTFUL_API_ENDPOINT` which is of the format https://graphql.contentful.com/content/v1/spaces/<space-id>
## Migrations
Execute the following command inside `hasura` to apply the migrations
```bash
hasura metadata apply
hasura migrate apply
hasura metadata reload
```
This will create all the necessary tables, relationships and remote joins.
## Run the app
You can start the development server with the following command:
```bash
gatsby develop
```
The app runs at `localhost:8000` by default.

# gatsby-postgres-graphql
Boilerplate to get started with Gatsby, Hasura GraphQL engine as CMS and postgres as database using the awesome plugin [gatsby-source-graphql](https://github.com/gatsbyjs/gatsby/tree/master/packages/gatsby-source-graphql).
[![Edit gatsby-postgres-graphql](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/github/hasura/graphql-engine/tree/master/community/sample-apps/gatsby-postgres-graphql?fontsize=14)
![Gatsby Postgres GraphQL](./assets/gatsby-postgres-graphql.png)
# Tutorial
- Deploy GraphQL Engine on Hasura Cloud and setup PostgreSQL via Heroku:
[![Deploy to Hasura Cloud](https://graphql-engine-cdn.hasura.io/img/deploy_to_hasura.png)](https://cloud.hasura.io/signup)
- Get the Hasura app URL (say `gatsby-graphql.hasura.app`)
- Clone this repo:
```bash
git clone https://github.com/hasura/graphql-engine
cd graphql-engine/community/sample-apps/gatsby-postgres-graphql
```
- Create `author` table:
Open Hasura console: visit https://gatsby-graphql.hasura.app on a browser
Navigate to `Data` section in the top nav bar and create a table as follows:
![Create author table](./assets/add_table.jpg)
- Insert sample data into `author` table:
![Insert data into author table](./assets/insert_data.jpg)
Verify if the row is inserted successfully
![Insert data into author table](./assets/browse_rows.jpg)
- Install npm modules:
```bash
npm install
```
- Configure gatsby to use `gatsby-source-graphql` plugin and a connection GraphQL url to stitch the schema.
```js
{
plugins: [
{
resolve: "gatsby-source-graphql", // <- Configure plugin
options: {
typeName: "HASURA",
fieldName: "hasura", // <- fieldName under which schema will be stitched
url: process.env.GATSBY_HASURA_GRAPHQL_URL,
refetchInterval: 10 // Refresh every 10 seconds for new data
}
}
];
}
```
- Run the app:
```bash
GATSBY_HASURA_GRAPHQL_URL=https://gatsby-graphql.hasura.app/v1/graphql npm run develop
```
- Test the app
Visit [http://localhost:8000](http://localhost:8000) to view the app
![Demo app](./assets/test_app.jpg)
# Make a GraphQL query from your component using hooks
1. Create a component named `AuthorList.js`:
```js
import React from "react";
import { useQuery } from "@apollo/react-hooks";
import { gql } from "apollo-boost";
const GET_AUTHORS = gql`
query {
author {
id
name
}
}
`;
const AuthorList = () => {
const { loading, error, data } = useQuery(GET_AUTHORS);
if (loading) return "loading...";
if (error) return `error: ${error.message}`;
return (
<div>
{data.author.map((author, index) => (
<div key={index}>
<h2>{author.name}</h2>
</div>
))}
</div>
);
};
export default AuthorList;
export { GET_AUTHORS };
```
# Make a GraphQL mutation using hooks
Additional packages are needed to be added to support mutations: <br/>
`npm install @apollo/react-hooks apollo-boost isomorphic-fetch`
1. Create an `apollo.js` util file:
```js
import ApolloClient from "apollo-boost";
import fetch from "isomorphic-fetch";
export const client = new ApolloClient({
uri: process.env.GATSBY_HASURA_GRAPHQL_URL,
fetch
});
```
2. Create `gatsby-browser.js` and `gatsby-ssr.js`
```js
import React from "react";
import { ApolloProvider } from "@apollo/react-hooks";
import { client } from "./src/utils/apollo";
export const wrapRootElement = ({ element }) => (
<ApolloProvider client={client}>{element}</ApolloProvider>
);
```
3. Create an `AddAuthor.js` component to add mutations:
```js
import React, { useState } from "react";
import { useMutation } from "@apollo/react-hooks";
import { gql } from "apollo-boost";
import { GET_AUTHORS } from "./AuthorList";
const ADD_AUTHOR = gql`
mutation insert_author($name: String!) {
insert_author(objects: { name: $name }) {
returning {
id
name
}
}
}
`;
const AddAuthor = () => {
const [author, setAuthor] = useState("");
const [insert_author, { loading, error }] = useMutation(ADD_AUTHOR, {
update: (cache, { data }) => {
setAuthor("");
const existingAuthors = cache.readQuery({
query: GET_AUTHORS
});
// Add the new author to the cache
const newAuthor = data.insert_author.returning[0];
cache.writeQuery({
query: GET_AUTHORS,
data: {author: [newAuthor, ...existingAuthors.author]}
});
}
});
if (loading) return "loading...";
if (error) return `error: ${error.message}`;
const handleSubmit = event => {
event.preventDefault();
insert_author({
variables: {
name: author
}
});
};
return (
<form onSubmit={handleSubmit}>
<label htmlFor="author">
Add Author:
<input
name="author"
value={author}
onChange={event => setAuthor(event.target.value)}
/>
</label>
<button type="submit">ADD</button>
</form>
);
};
export default AddAuthor;
```
4. Run the app and test mutation. New data will be added to the top via a cache update.

# GraphQL Benchmarking
Uses the [Chinook sample database](https://github.com/lerocha/chinook-database). Tested on macOS Ventura 13.1.
## Instructions
1. Checkout [https://github.com/hasura/graphql-bench](https://github.com/hasura/graphql-bench) and build the docker container with `make build_local_docker_image`
1. Run `docker compose -f docker-compose.hasura.yml up -d` to bootstrap Postgres with Chinook.
1. After a few minutes check the Hasura docker logs to see if Hasura is running, which implies the database is now bootstrapped. Run `docker compose -f docker-compose.hasura.yml down`
1. Run the benchmarks `sh benchmark.sh`
1. Open the results on the GraphQL bench website [https://hasura.github.io/graphql-bench/app/web-app/](https://hasura.github.io/graphql-bench/app/web-app/)
