    eslint-plugin-no-unused-vars-rest

    DEPRECATED: As of ESLint 3.15.0 this functionality is supported by the core no-unused-vars rule.

    An enhanced version of the ESLint core rule no-unused-vars with allowances for experimental object rest properties.

    This plugin provides a single rule which functions the same as the core rule no-unused-vars, except it adds the ignoreDestructuredVarsWithRest option. Enabling this option will allow unused variables appearing in destructuring assignments that also contain experimental rest properties. This is useful for shallow-cloning an object while omitting certain properties.

    Installation

    Install ESLint and eslint-plugin-no-unused-vars-rest:

    $ npm install --save-dev eslint eslint-plugin-no-unused-vars-rest
    

    Usage

    Add no-unused-vars-rest to the plugins section of your .eslintrc configuration file, and configure the rule under the rules section. Don't forget to disable the core rule no-unused-vars.

    {
      "plugins": [
        "no-unused-vars-rest"
      ],
      "rules": {
        "no-unused-vars": 0,
        "no-unused-vars-rest/no-unused-vars": [2, {"ignoreDestructuredVarsWithRest": true}]
      }
    }

    Alternatively you may use the plugin's recommended configuration, which applies the above configuration.

    {
      "extends": ["plugin:no-unused-vars-rest/recommended"]
    }

    When not using this rule the following pattern is considered a problem by the core rule no-unused-vars:

    const { extra, ...rest } = blah; // Error 'extra' is defined but never used.
    return rest;

    When using this rule with ignoreDestructuredVarsWithRest: true the following pattern is acceptable:

    const { extra, ...rest } = blah;
    return rest;
