GraphQL: Language Feature Support

I can't load .graphqlconfig files anymore

Note: this option has been set to be enabled by default, however graphql-config maintainers do not want to continue to support the legacy format (mostly kept for companies where intellij users are stuck on the old config format), so please migrate to the new graphql-config format as soon as possible!

If you need to use a legacy config file, then you just need to enable legacy mode for graphql-config:

"graphql-config.load.legacy": true

Go to definition is not working for my URL

You can try the new experimental cacheSchemaFileForLookup option. NOTE: this will disable all definition lookup for local SDL graphql schema files, and only perform lookup of the result an SDL result of graphql-config getSchema()

To enable, add this to your settings:

"vscode-graphql.cacheSchemaFileForLookup": true,

you can also use graphql config if you need to mix and match these settings:

schema: 'http://myschema.com/graphql'
extensions:
  languageService:
    cacheSchemaFileForLookup: true
projects:
  project1:
    schema: 'project1/schema/schema.graphql'
    documents: 'project1/queries/**/*.{graphql,tsx,jsx,ts,js}'
    extensions:
      languageService:
        cacheSchemaFileForLookup: false

  project2:
    schema: 'https://api.spacex.land/graphql/'
    documents: 'project2/queries.graphql'
    extensions:
      endpoints:
        default:
          url: 'https://api.spacex.land/graphql/'
      languageService:
        # Do project configs inherit parent config?
        cacheSchemaFileForLookup: true

The extension fails with errors about duplicate types

Make sure that you aren't including schema files in the documents blob

The extension fails with errors about missing scalars, directives, etc

Make sure that your schema pointers refer to a complete schema!

In JSX and TSX files I see completion items I don't need

The way vscode lets you filter these out is on the user end

So you'll need to add something like this to your global vscode settings:

"[typescriptreact]": {
  "editor.suggest.filteredTypes": {
    "snippet": false
  }
},
"[javascriptreact]": {
  "editor.suggest.filteredTypes": {
    "snippet": false
  }
}

My graphql config file is not at the root

Good news, we have configs for this now!

You can search a folder for any of the matching config file names listed above:

"graphql-config.load.rootDir": "./config"

Or a specific filepath:

"graphql-config.load.filePath": "./config/my-graphql-config.js"

Or a different configName that allows different formats:

"graphql-config.load.rootDir": "./config",
"graphql-config.load.configName": "acme"

which would search for ./config/.acmerc, .config/.acmerc.js, .config/acme.config.json, etc matching the config paths above

If you have multiple projects, you need to define one top-level config that defines all project configs using projects

How do I highlight an embedded graphql string?

If you aren't using a template tag function such as gql or graphql, and just want to use a plain string, you can use an inline #graphql comment:

const myQuery = `#graphql
  query {
    something
  }
`;

or

const myQuery =
  /* GraphQL */

  `
    query {
      something
    }
  `;

Known Issues

• the output channel occasionally shows "definition not found" when you first start the language service, but once the definition cache is built for each project, definition lookup will work. so if a "peek definition" fails when you first start the editor or when you first install the extension, just try the definition lookup again.

Attribution

Thanks to apollo for their graphql-vscode grammars! We have borrowed from these on several occasions. If you are looking for the most replete set of vscode grammars for writing your own extension, look no further!

Development

This plugin uses the GraphQL language server

1. Clone the repository - https://github.com/graphql/graphiql
2. yarn
3. Run "VScode Extension" launcher in vscode
4. This will open another VSCode instance with extension enabled
5. Open a project with a graphql config file - ":electric_plug: graphql" in VSCode status bar indicates that the extension is in use
6. Logs for GraphQL language service will appear in output section under GraphQL Language Service
