Hasura GraphQL Engine
The Hasura engine is an open source project which supercharges the building of modern applications by providing access to data via a single, composable, secure API endpoint.
Hasura V3
The future of data delivery is GA: Supporting PostgreSQL (and its flavors), MongoDB, ClickHouse, and MS SQL Server. Also supports writing custom business logic using the Typescript, Python, and Go Connector SDKs. Here is the recommended Getting Started guide on DDN.
The Hasura v3 engine code, which powers Hasura DDN, is in the v3 folder of this repo. You can find more detailed
information about in this v3 README.
The Hasura DDN architecture includes Data Connectors to connect to data sources. All Hasura connectors are also available completely open source. Check out the Connector Hub which lists all available connectors.
Hasura V2
Hasura V2 is the current stable version of the Hasura GraphQL Engine. Please find more
detailed information about the V2 Hasura Graphql Engine in the v2 folder and this README.
Cloning repository
This repository is a large and active mono-repo containing many parts of the Hasura ecosystem and a long git history, that can make the first time cloning of the repository slow and consume a lot of disk space. We recommend following if you are facing cloning issues.
Shallow clone
This will only clone the latest commit and ignore all historical commits.
git clone https://github.com/hasura/graphql-engine.git --depth 1
Git checkout with only Hasura V3 engine code
git clone --no-checkout https://github.com/hasura/graphql-engine.git --depth 1
cd graphql-engine
git sparse-checkout init --cone
git sparse-checkout set v3
git checkout @
This checkouts the top level files and only the v3 folder which contains the Hasura V3 Engine code.
