gulp-coffeescript

CoffeeScript 2 alpha plugin for gulp

CoffeeScript 2 is coming! It adds support for ES2015 classes, async/await, and generates JavaScript using ES2015+ syntax. Learn more

Usage

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

gulp.task('coffee', function() {
  gulp.src('./src/*.coffee')
    .pipe(coffeescript({bare: true}).on('error', gutil.log))
    .pipe(gulp.dest('./public/'));
});

Error handling

gulp-coffeescript will emit an error for cases such as invalid coffeescript syntax. If uncaught, the error will crash gulp.

You will need to attach a listener (i.e. .on('error')) for the error event emitted by gulp-coffeescript:

var coffeeStream = coffeescript({bare: true});

// Attach listener
coffeeStream.on('error', function(err) {});

In addition, you may utilize gulp-util's logging function:

var gutil = require('gulp-util');

// ...

var coffeeStream = coffeescript({bare: true});

// Attach listener
coffeeStream.on('error', gutil.log);

Since .on(...) returns this, you can compact it as inline code:

gulp.src('./src/*.coffee')
  .pipe(coffeescript({bare: true}).on('error', gutil.log))
  // ...

Options

The options object supports the same options as the standard CoffeeScript 2 compiler

Source maps

gulp-coffeescript can be used in tandem with gulp-sourcemaps to generate source maps for the coffee to javascript transition. You will need to initialize gulp-sourcemaps prior to running the gulp-coffeescript compiler and write the source maps after.

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

gulp.src('./src/*.coffee')
  .pipe(sourcemaps.init())
  .pipe(coffeescript())
  .pipe(sourcemaps.write())
  .pipe(gulp.dest('./dest/js'));

// will write the source maps inline in the compiled javascript files

By default, gulp-sourcemaps writes the source maps inline in the compiled javascript files. To write them to a separate file, specify a relative file path in the sourcemaps.write() function.

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

gulp.src('./src/*.coffee')
  .pipe(sourcemaps.init())
  .pipe(coffeescript({ bare: true })).on('error', gutil.log)
  .pipe(sourcemaps.write('./maps'))
  .pipe(gulp.dest('./dest/js'));

// will write the source maps to ./dest/js/maps
