Documentation

A multi-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

Example Usage

module.exports = function (grunt) {
  'use strict';

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

  grunt.initConfig({
    jslint: { // configure the task
      // lint your project's server code
      server: {
        src: [ // some example files
          'server/lib/*.js',
          'server/routes/*.js',
          'server/*.js',
          'server/test/*.js'
        ],
        exclude: [
          'server/config.js'
        ],
        directives: { // example directives
          node: true,
          todo: true
        },
        options: {
          junit: 'out/server-junit.xml', // write the output to a JUnit XML
          log: 'out/server-lint.log',
          jslintXml: 'out/server-jslint.xml',
          errorsOnly: true, // only display errors
          failOnError: false, // defaults to true
          checkstyle: 'out/server-checkstyle.xml' // write a checkstyle-XML
        }
      },
      // lint your project's client code
      client: {
        src: [
          'client/**/*.js'
        ],
        directives: {
          browser: true,
          predef: [
            'jQuery'
          ]
        },
        options: {
