JSPM – gulp-concat@2.6.1

Package Exports

gulp-concat

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (gulp-concat) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

Install package with NPM and add it to your development dependencies:

npm install --save-dev gulp-concat

Information

Package	gulp-concat
Description	Concatenates files
Node Version	>= 0.10

Usage

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

gulp.task('scripts', function() {
  return gulp.src('./lib/*.js')
    .pipe(concat('all.js'))
    .pipe(gulp.dest('./dist/'));
});

This will concat files by your operating systems newLine. It will take the base directory from the first file that passes through it.

Files will be concatenated in the order that they are specified in the gulp.src function. For example, to concat ./lib/file3.js, ./lib/file1.js and ./lib/file2.js in that order, the following code will create a task to do that:

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

gulp.task('scripts', function() {
  return gulp.src(['./lib/file3.js', './lib/file1.js', './lib/file2.js'])
    .pipe(concat('all.js'))
    .pipe(gulp.dest('./dist/'));
});

To change the newLine simply pass an object as the second argument to concat with newLine being whatever (\r\n if you want to support any OS to look at it)

For instance:

.pipe(concat('main.js', {newLine: ';'}))

To specify cwd, path and other vinyl properties, gulp-concat accepts Object as first argument:

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

gulp.task('scripts', function() {
  return gulp.src(['./lib/file3.js', './lib/file1.js', './lib/file2.js'])
    .pipe(concat({ path: 'new.js', stat: { mode: 0666 }}))
    .pipe(gulp.dest('./dist'));
});

This will concat files into ./dist/new.js.

Source maps

Source maps can be generated by using gulp-sourcemaps:

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

gulp.task('javascript', function() {
  return gulp.src('src/**/*.js')
    .pipe(sourcemaps.init())
      .pipe(concat('all.js'))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('dist'));
});
