Validates JavaScript files with JSLint as a grunt task.

Install this grunt plugin next to your project's grunt.js gruntfile with: npm install grunt-jslint

Then add this line to your project's gruntfile:

grunt.loadNpmTasks('grunt-jslint');

A single-task to validate your JavaScript files with JSLint.

Supports the following options:

• files An array of files or wildcards which you want to be validated by JSLint
• exclude An array of files or wildcards which you do not want to be validated by JSLint
• directives Configuration options/settings to pre-define in JSLint. Pre-defined globals are included within this object as predef: ['myglobal']
• options
  • errorsOnly A Boolean option which tells the plugin to only display errors when set to true
  • log A String/filepath option which, when provided, tells the plugin where to write a verbose log to
  • junit A String/filepath option which, when provided, tells the plugin where to write a JUnit-style XML file to
  • failOnError A Boolean option - defaults to true; when set to false, grunt will not fail if JSLint detects an error
  • checkstyle A String/filepath option which, when provided, tells the plugin where to write a CheckStyle-XML file to
  • shebang Ignore shebang lines (#!/usr/bin/whatever) from files

/*jslint node:true*/

module.exports = function (grunt) {

  'use strict';

  grunt.loadNpmTasks('grunt-jslint'); // load the task

  grunt.initConfig({
    watch: {
      files: '<config:jslint.files>',
      tasks: 'jslint'
    },

    jslint: { // configure the task
      files: [ // some example files
        'grunt.js',
        'src/**/*.js'
      ],
      exclude: [
        '**/ignore-*.js',
        'bananas.js'
      ],
      directives: { // example directives
        browser: true,
        unparam: true,
        todo: true,
        predef: [ // array of pre-defined globals
          'jQuery'
        ]
      },
      options: {
        junit: 'out/junit.xml', // write the output to a JUnit XML
        log: 'out/lint.log',
        jslintXml: 'out/jslint_xml.xml',
        errorsOnly: true, // only display errors
        failOnError: false, // defaults to true
        shebang: true, // ignore shebang lines
        checkstyle: 'out/checkstyle.xml' // write a checkstyle-XML
      }
    }

  });

  grunt.registerTask('default', 'watch');
};

All files should be validated with JSLint. Bug fixes and/or new features must be accompanied by a passing test. Tests are written with vows.

Run grunt jslint in the root of your repository.

Run ./test.sh in the root of your repository.
