A plugin for the code linter ESLint to lint specific details about Relay.

eslint-plugin-relay

eslint-plugin-relay is a plugin for ESLint to catch common problems in code using Relay early.

Install

npm i --save-dev eslint-plugin-relay

How To Use

1. Add "relay" to your eslint plugins section.
2. Add the relay rules such as "relay/graphql-syntax": "error" to your eslint rules section, see the example for all rules.

Example .eslintrc.js:

module.exports = {
  // Other eslint properties here
  rules: {
    'relay/graphql-syntax': 'error',
    'relay/compat-uses-vars': 'warn',
    'relay/graphql-naming': 'error',
    'relay/generated-flow-types': 'warn',
    'relay/must-colocate-fragment-spreads': 'warn',
    'relay/no-future-added-value': 'warn',
    'relay/unused-fields': 'warn',
    'relay/function-required-argument': 'warn',
    'relay/hook-required-argument': 'warn'
  },
  plugins: ['relay']
};

You can also enable all the recommended or strict rules at once. Add plugin:relay/recommended or plugin:relay/strict in extends:

{
  "extends": [
    "plugin:relay/recommended"
  ]
}

Suppressing rules within graphql tags

The following rules support suppression within graphql tags:

• relay/unused-fields
• relay/must-colocate-fragment-spreads

Supported rules can be suppressed by adding # eslint-disable-next-line relay/name-of-rule to the preceding line:

graphql`fragment foo on Page {
  # eslint-disable-next-line relay/must-colocate-fragment-spreads
  ...unused1
}`

Note that only the eslint-disable-next-line form of suppression works. eslint-disable-line doesn't currently work until graphql-js provides support for parsing Comment nodes in their AST.
