Registry GraphQL

A GraphQL wrapper for the Registry API.

This project contains a small proxy for the Registry API that provides a GraphQL interface.

It uses the graphql-go package.

Limitations

Currently the GraphQL interface is read-only (no mutations) and does not provide access to spec revisions or artifact values.

Invocation

Just run the registry-graphql program. It uses the registry project's pkg/connection to get an authenticated connection to a Registry API server. Because it serves static files, it should be run in the same directory as its source files.

If you're building a React or other browser-hosted client application, you can use the -cors-allow-origin flag to allow CORS requests while you are developing your app. This allows you to specify a single allowed origin, which can include *, which allows all CORS requests. Take care to quote the * to avoid shell expansion:

registry-graphql -cors-allow-origin '*'

Usage

After you've started the registry-graphql server, visit http://localhost:8088 to open the GraphiQL browser. Then use standard GraphQL to explore the schema and make queries. For example, to lookup a project by name, enter:

{
  project (id: "projects/test") {
    id
    display_name
  }
}

Pagination

List results are paginated. As an example, here is a fully-specified request for a page of projects:

{
  projects (first: 2, after:$cursor) {
    edges {
      node {
        id
      }
    }
    pageInfo {
      endCursor
    }
  }
}

Schema

registry.graphql is an SDL schema that was produced with prisma-labs/get-graphql-schema.

$ get-graphql-schema http://localhost:8088/graphql > registry.graphql
