SYNC missed versions from official npm registry.

npm version

This project integrates GraphQL and ESLint, for a better developer experience.

Created and maintained by The Guild

Key Features

  • ???? Integrates with ESLint core (as a ESTree parser).
  • ???? Works on .graphql files, gql usages and /* GraphQL */ magic comments.
  • ???? Lints both GraphQL schema and GraphQL operations.
  • ???? Extended type info for more advanced usages
  • ???? Supports ESLint directives (for example: disable-next-line)
  • ???? Easily extendable - supports custom rules based on GraphQL's AST and ESLint API.
  • ???? Validates, lints, prettifies and checks for best practices across GraphQL schema and GraphQL operations.
  • ???? Integrates with graphql-config
  • ???? Integrates and visualizes lint issues in popular IDEs (VSCode / WebStorm)

Special thanks to ilyavolodin for his work on a similar project!

Getting Started


Start by installing the plugin package, which includes everything you need:

yarn add -D @graphql-eslint/eslint-plugin

Or, with NPM:

npm install --save-dev @graphql-eslint/eslint-plugin

Also, make sure you have graphql dependency in your project.


To get started, create an override configuration for your ESLint, while applying it to to .graphql files (do that even if you are declaring your operations in code files):

  "overrides": [
      "files": ["*.graphql"],
      "parser": "@graphql-eslint/eslint-plugin",
      "plugins": ["@graphql-eslint"],
      "rules": {

If you are using code files to store your GraphQL schema or your GraphQL operations, you can extend the behaviour of ESLint and extract those, by adding an additional override that does that extraction processes:

  "overrides": [
      "files": ["*.tsx", "*.ts", "*.jsx", "*.js"],
      "processor": "@graphql-eslint/graphql"
      "files": ["*.graphql"],
      "parser": "@graphql-eslint/eslint-plugin",
      "plugins": ["@graphql-eslint"],
      "rules": { ... }

Extended linting rules with GraphQL Schema

If you are using graphql-config - you are good to go. This package integrates with it automatically, and will use it to load your schema!

Linting process can be enriched and extended with GraphQL type information, if you are able to provide your GraphQL schema.

The parser allow you to specify a json file / graphql files(s) / url / raw string to locate your schema (We are using graphql-tools to do that). Just add parserOptions.schema to your configuration file:

  "files": ["*.graphql"],
  "parser": "@graphql-eslint/eslint-plugin",
  "plugins": ["@graphql-eslint"],
  "parserOptions": {
    "schema": "./schema.graphql"

You can find a complete documentation of the parserOptions here

Some rules requires type information to operate, it's marked in the docs of each plugin!

VSCode Integration

By default, ESLint VSCode plugin will not lint files with extensions other then js, jsx, ts, tsx.

In order to enable it processing other extensions, add the following section in settings.json or workspace configuration.

  "eslint.validate": ["javascript", "javascriptreact", "typescript", "typescriptreact", "graphql"],
  "eslint.options": {
    "extentions": [".js", ".graphql"]

Disabling Rules

The graphql-eslint parser looks for GraphQL comments syntax (marked with #) and will send it to ESLint as directives. That means, you can use ESLint directives syntax to hint ESLint, just like in any other type of files.

To disable ESLint for a specific line, you can do:

# eslint-disable-next-line
type Query {
  foo: String!

You can also specify specific rules to disable, apply it over the entire file, next-line or (current) line.

You can find a list of ESLint directives here.

Available Rules

You can find a complete list of all available rules here

This repo doesn't exports a "recommended" set of rules - feel free to recommend us!
