Information

Packagegulp-jshint
Description JSHint plugin for gulp
Node Version >= 0.4

Install

npm install gulp-jshint --save-dev

Usage

var jshint = require('gulp-jshint');
var gulp   = require('gulp');

gulp.task('lint', function() {
  return gulp.src('./lib/*.js')
    .pipe(jshint())
    .pipe(jshint.reporter('YOUR_REPORTER_HERE'));
});

Options

Plugin options:

  • lookup
    • Default is true
    • When false do not lookup .jshintrc files. See the JSHint docs for more info.

You can pass in any other options and it passes them straight to JSHint. Look at their README for more info. You can also pass in the location of your jshintrc file as a string and it will load options from it.

Results

Adds the following properties to the file object:

  file.jshint.success = true; // or false
  file.jshint.errorCount = 0; // number of errors returned by JSHint
  file.jshint.results = []; // JSHint errors, see [http://jshint.com/docs/reporters/](http://jshint.com/docs/reporters/)
  file.jshint.data = []; // JSHint returns details about implied globals, cyclomatic complexity, etc
  file.jshint.opt = {}; // The options you passed to JSHint

Reporters

JSHint reporters

Built-in

You can choose any JSHint reporter when you call

stuff
  .pipe(jshint())
  .pipe(jshint.reporter('default'))

External

Let's use jshint-stylish as an example

var stylish = require('jshint-stylish');

stuff
  .pipe(jshint())
  .pipe(jshint.reporter(stylish))
  • OR -
stuff
  .pipe(jshint())
  .pipe(jshint.reporter('jshint-stylish'))

JSHint plugins have no good module format so I tried to support all of them I saw in the wild. Hopefully it worked, but if a JSHint plugin isn't working with this library feel free to open an issue.

Fail Reporter

Do you want the task to fail when a JSHint error happens? gulp-jshint includes a simple utility for this.

This example will log the errors using the stylish reporter, then fail if JSHint was not a success.

stuff
  .pipe(jshint())
  .pipe(jshint.reporter('jshint-stylish'))
  .pipe(jshint.reporter('fail'))

Custom Reporters

Custom reporters don't interact with this module at all. jshint will add some attributes to the file object and you can add a custom reporter downstream.

var jshint = require('gulp-jshint');
var map = require('map-stream');

var myReporter = map(function (file, cb) {
  if (!file.jshint.success) {
    console.log('JSHINT fail in '+file.path);
    file.jshint.results.forEach(function (err) {
      if (err) {
        console.log(' '+file.path + ': line ' + err.line + ', col ' + err.character + ', code ' + err.code + ', ' + err.reason);
      }
    });
  }
  cb(null, file);
});

gulp.task('lint', function() {
  return gulp.files('./lib/*.js')
    .pipe(jshint())
    .pipe(myReporter);
});
