Validate files with JSHint.
This plugin requires Grunt ~0.4.0
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');
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.
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:
Type: Object
Default value: 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.
Type: String
Default value: null
If this 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.
Type: String
Default value: ''
A list of non-dot-js extensions to check.
Type: Array
Default value: null
A list of files and dirs to ignore. This will override your .jshintignore
file if set and does not merge.
Type: Boolean
Default value: false
Set force
to true
to report JSHint errors but not fail the task.
Type: String
Default value: 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.
Type: String
Default value: 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.
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 subdirectores, using the default JSHint options.
// Project configuration.
grunt.initConfig({
jshint: {
all: ['Gruntfile.js', 'lib/**/*.js', 'test/**/*.js']
}
});
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']
}
});
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']
},
}
},
});
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'],
},
},
});
