What is GraphQL?
GraphQL is a query language for APIs that allows clients to request exactly the data they need, making it possible to get all required data in a limited number of requests.
The GraphQL data (fields) can be described in the form of types, allowing clients to use clientside GraphQL libraries to consume the API and avoid manual parsing.
Since there's no fixed endpoints and datamodel, new abilities can be added to the API without creating breaking changes. This allows us to have a versionless API as described in the GraphQL documentation.
We want the GraphQL API to be the primary means of interacting programmatically with GitLab. To achieve this, it needs full coverage - anything possible in the REST API should also be possible in the GraphQL API.
To help us meet this vision, the frontend should use GraphQL in preference to the REST API for new features.
There are no plans to deprecate the REST API. To reduce the technical burden of supporting two APIs in parallel, they should share implementations as much as possible.
The GraphQL API includes the following queries at the root level:
project: Project information, with many of its associations such as issues and merge requests.
group: Basic group information and epics (ULTIMATE) are currently supported.
namespace: Within a namespace it is also possible to fetch
currentUser: Information about the currently logged in user.
metaData: Metadata about GitLab and the GraphQL API.
snippets: Snippets visible to the currently logged in user.
New associations and root level objects are constantly being added. See the GraphQL API Reference for up-to-date information.
