broccoli-lint-eslint

broccoli-lint-eslint

Lint JavaScript with ESLint as part of your Broccoli build pipeline.

Most of the test setup and the build configuration is based on sindresorhus/grunt-eslint. The internal validation is heavily inspired by eslint cli.js.

Installation

npm install --save broccoli-lint-eslint

broccoli-lint-eslint@5 uses eslint@5 which requires Node.js 6 or above. If you need support for Node.js 4, you may use broccoli-lint-eslint@4 which uses eslint@4 and is compatible with Node.js 4:

npm install --save broccoli-lint-eslint@4

Usage

var ESLint = require('broccoli-lint-eslint');
var outputNode = ESLint.create(inputNode, options);

API

• inputNode A Broccoli node

• options {Object}: Options to control how broccoli-lint-eslint is run.

  • format {string|function}: The path, or function reference, to a custom formatter (See eslint/tree/master/lib/formatters for alternatives).

    Default: 'eslint/lib/formatters/stylish'

  • testGenerator {function(relativePath, errors), returns reporter output string}: The function used to generate test modules. You can provide a custom function for your client side testing framework of choice.

    Default: null

    • relativePath - The relative path to the file being tested.
    • errors - An array of eslint error objects found.

    If you provide a string one of the predefined test generators is used. Currently supported are qunit and mocha.

    Example usage:

    var path = require('path');
    
    function testGenerator(relativePath, errors) {
      return "module('" + path.dirname(relativePath) + "');\n";
             "test('" + relativePath + "' should pass ESLint', function() {\n" +
             "  ok(" + passed + ", '" + moduleName + " should pass ESLint." + (errors ? "\\n" + errors : '') + "');\n" +
             "});\n";
    };
    
    return ESLint.create(inputNode, {
      options: {
        configFile: this.eslintrc.app + '/eslint.json'
      },
      testGenerator: testGenerator
    });
    

  • group {string|undefined}: Groups the generated ESLint tests into a single file and test suite with the given group name.

    Default: undefined

  • throwOnError {boolean}: Cause exception error on first violation with error-level severity.

    Default: false

  • throwOnWarn {boolean}: Cause exception error on first violation with warn-level severity. NOTE: Setting this to true will automatically enable throwOnError behavior.

    Default: false

  • persist {boolean}: Persist the state of filter output across restarts

    Default: false

  • console: {Object}: A custom console object with a log method for broccoli-lint-eslint to use when logging formatter output.

    Default: The global console object

  • options {options}: Options native to ESLint CLI. While all options will be passed to the ESLint CLIEngine, these are the ones that broccoli-lint-eslint makes use of in particular:

    • configFile {string}: Path to eslint configuration file.

      Default: ./eslintrc

    • rulePaths {Array}: Paths to a directory with custom rules. Your custom rules will be used in addition to the built-in ones. Recommended read: Working with Rules.

      Default: built-in rules directory

    • ignore {boolean}: false disables use of .eslintignore, ignorePath and ignorePattern

      Default: true

  • extensions {Array}: File extensions to lint. NOTE: If you add Typescript files typescript-eslint-parser has to be installed and specified as the parser. For more information take a look at the typescript-eslint-parser

    Default: ['js']
