Installation

You'll first need to install ESLint:

npm install eslint --save-dev

Next, install eslint-plugin-promise:

npm install eslint-plugin-promise --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-promise globally.

Usage

Add promise to the plugins section of your .eslintrc.json configuration file. You can omit the eslint-plugin- prefix:

{
  "plugins": ["promise"]
}

Then configure the rules you want to use under the rules section.

{
  "rules": {
    "promise/always-return": "error",
    "promise/no-return-wrap": "error",
    "promise/param-names": "error",
    "promise/catch-or-return": "error",
    "promise/no-native": "off",
    "promise/no-nesting": "warn",
    "promise/no-promise-in-callback": "warn",
    "promise/no-callback-in-promise": "warn",
    "promise/avoid-new": "warn",
    "promise/no-new-statics": "error",
    "promise/no-return-in-finally": "warn",
    "promise/valid-params": "warn",
    "promise/no-multiple-resolved": "error"
  }
}

or start with the recommended rule set:

• eslint.config.js:

  import pluginPromise from 'eslint-plugin-promise'
  export default [
    // ...
    pluginPromise.configs['flat/recommended'],
  ]
  

• .eslintrc.*:

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