grunt-contrib-jshint v1.1.0 
Validate files with JSHint
Getting Started
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-contrib-jshint --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-contrib-jshint');
Jshint task
Run this task with the grunt jshint command.
Task targets, files and options may be specified according to the grunt Configuring tasks guide.
For more explanations of the lint errors JSHint will throw at you please visit jslinterrors.com.
Options
Any specified option will be passed through directly to JSHint, thus you can specify any option that JSHint supports. See the JSHint documentation for a list of supported options.
A few additional options are supported:
globals
Type: Object
Default: null
A map of global variables, with keys as names and a boolean value to determine if they are assignable. This is not a standard JSHint option, but is passed into the JSHINT function as its third argument. See the JSHint documentation for more information.
jshintrc
Type: String or true
Default: null
If set to true, no config will be sent to JSHint and JSHint will search for .jshintrc files relative to the files being linted.
If a filename is specified, options and globals defined therein will be used. The jshintrc file must be valid JSON and looks something like this:
{
"curly": true,
"eqnull": true,
"eqeqeq": true,
"undef": true,
"globals": {
"jQuery": true
}
}
Be aware that jshintrc settings are not merged with your Grunt options.
extensions
Type: String
Default: ''
A list of non-dot-js extensions to check.
ignores
Type: Array
Default: null
A list of files and dirs to ignore. This will override your .jshintignore file if set and does not merge.
force
Type: Boolean
Default: false
Set force to true to report JSHint errors but not fail the task.
reporter
Type: String
Default: null
Allows you to modify this plugins output. By default it will use a built-in Grunt reporter. Set the path to your own custom reporter or to one of the built-in JSHint reporters: jslint or checkstyle.
See also: Writing your own JSHint reporter.
You can also use an external reporter. For example jshint-stylish:
$ npm install --save-dev jshint-stylish
options: {
reporter: require('jshint-stylish')
}
reporterOutput
Type: String
Default: null
Specify a filepath to output the results of a reporter. If reporterOutput is specified then all output will be written to the given filepath instead of printed to stdout.
Usage examples
Wildcards
In this example, running grunt jshint:all (or grunt jshint because jshint is a multi task) will lint the project's Gruntfile as well as all JavaScript files in the lib and test directories and their subdirectories, using the default JSHint options.
// Project configuration.
grunt.initConfig({
jshint: {
all: ['Gruntfile.js', 'lib/**/*.js', 'test/**/*.js']
}
});
Linting before and after concatenating
In this example, running grunt jshint will lint both the "beforeconcat" set and "afterconcat" sets of files. This is not ideal, because dist/output.js may get linted before it gets created via the grunt-contrib-concat plugin concat task.
In this case, you should lint the "beforeconcat" files first, then concat, then lint the "afterconcat" files, by running grunt jshint:beforeconcat concat jshint:afterconcat.
// Project configuration.
grunt.initConfig({
concat: {
dist: {
src: ['src/foo.js', 'src/bar.js'],
dest: 'dist/output.js'
}
},
jshint: {
beforeconcat: ['src/foo.js', 'src/bar.js'],
afterconcat: ['dist/output.js']
}
});
Specifying JSHint options and globals
In this example, custom JSHint options are specified. Note that when grunt jshint:uses_defaults is run, those files are linted using the default options, but when grunt jshint:with_overrides is run, those files are linted using merged task/target options.
// Project configuration.
grunt.initConfig({
jshint: {
options: {
curly: true,
eqeqeq: true,
eqnull: true,
browser: true,
globals: {
jQuery: true
},
},
uses_defaults: ['dir1/**/*.js', 'dir2/**/*.js'],
with_overrides: {
options: {
curly: false,
undef: true,
},
files: {
src: ['dir3/**/*.js', 'dir4/**/*.js']
},
}
},
});
Ignoring specific warnings
If you would like to ignore a specific warning:
[L24:C9] W015: Expected '}' to have an indentation at 11 instead at 9.
You can toggle it by prepending - to the warning id as an option:
grunt.initConfig({
jshint: {
ignore_warning: {
options: {
'-W015': true,
},
src: ['**/*.js'],
},
},
});
