See the Reading GraphQL logs guide for tips on how to inspect logs If you are asked to review a merge request that modifies any GraphQL files or adds an endpoint, please have a look at The GraphQL framework has some specific gotchas to be aware of, and domain expertise is required to ensure they are satisfied. Reviewing merge requests with GraphQL changes You can access it in any GitLab environment on For example, the one for. GraphiQL is an interactive GraphQL API explorer where you can play around with existing queries. You can find theĮverything covered in this deep dive was accurate as of GitLab 11.9, and while specificĭetails may have changed after that release, it should still serve as a good introduction. With anyone who may work in this part of the codebase in the future. On the GitLab GraphQL API to share domain-specific knowledge In March 2019, Nick Thomas hosted a Deep Dive (GitLab team members only: ) Which is exposed as an API endpoint at /api/graphql. ( app/controllers/graphql_controller.rb#execute), ForĪll GraphQL queries are directed to a single endpoint In addition, we have a subscription to GraphQL Pro.
