Managing data with the Hasura Console

The Hasura Console is a web UI that allows you to manage your data and metadata. It is available at http://localhost:8080/console when you run Hasura locally, or from your project's Console endpoint when you use Hasura Cloud.

The data-management features (such as creating tables) are available in the Data tab. You can access your GraphQL API in the API tab and interact with it using the GraphiQL interface.

Console support

You can use these tools to manage your PostgreSQL database, but we recommend using your preferred PostgreSQL client instead. The Hasura Console is designed to be a tool for managing your GraphQL API, and not a full-fledged database management tool.

Required user role permissions

Below are the role permissions required for Hasura to perform all its functionality. Note that, with the exception of CONNECT and GRANT USAGE, the other features are opt-in, and not enabling them will simply mean that only the corresponding Hasura features will not work.

  • CONNECT is required in order for Hasura to connect to your Postgres data source.
  • You must GRANT USAGE to the Hasura user role for any schema you want to access via Hasura.
  • To allow queries and subscriptions via the GraphQL API, SELECT permissions are required.
  • Similarly, INSERT, UPDATE, and DELETE permissions are required for mutations.
  • The Hasura Console requires permissions such as REFERENCES and CREATE to make changes to your schema.
  • TRIGGER is required to use Event Triggers
  • If you want to use computed fields or user-defined Postgres functions, the EXECUTE permission is required.
