  # 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. <a href="https://hasura.io/"><img src="https://img.shields.io/badge/🏠_Visit-Hasura_Homepage-blue.svg?style=flat"></a> <a href="https://hasura.io/community/"><img src="https://img.shields.io/badge/😊_Join-Community-blue.svg?style=flat"></a> ## Hasura V3 [](https://hasura.io/docs/3.0/getting-started/quickstart/) 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](https://hasura.io/docs/3.0/getting-started/quickstart/) 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 this [v3 README](/v3/README.md). 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](https://hasura.io/connectors/) which lists all available connectors. ## Hasura V2 [](https://github.com/hasura/graphql-engine/releases/latest) [](https://hasura.io/docs) 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](V2-README.md). ## 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. ## Support & Troubleshooting To troubleshoot most issues, check out our documentation and community resources.
