gulp-concat-util Build Status

Gulp task to concat, prepend, append or transform files.

This implementation is relatively closes to the original gulp-concat plugin.

However this plugin provides .header(), .footer() & .scripts() helpers, and provides a passthrough option used in complex build worflow.

Getting Started

This plugin requires Gulp ^3.0.0

If you haven't used Gulp before, be sure to check out the Getting Started guide, as it explains how to create a Gulpfile as well as install and use Gulp plugins. Once you're familiar with that , you may install this plugin with this command:

npm install gulp-concat-util --save-dev

Once the plugin has been installed, it may be required inside your Gulpfile with this line of JavaScript:

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

Usage

var concat = require('gulp-concat-util');
 
gulp.task('concat:dist', function() {
  gulp.src('scripts/{,*/}*.js')
    .pipe(concat('combined.js'))
    .pipe(concat.header('// file: <%= file.path %>\n'))
    .pipe(concat.footer('\n// end\n'))
    .pipe(gulp.dest('dist'));
});

Advanced usage example, replacing any 'use strict;' statement found in the files with a single one at the top of the file

var concat = require('gulp-concat-util');
 
gulp.task('concat:dist', function() {
  gulp.src('scripts/{,*/}*.js')
    .pipe(concat(pkg.name + '.js', {process: function(src, filePath) { 
      // if you need the filename, example `myFileJs.js`, path.basename( filePath, '.js' )
      return (src.trim() + '\n').replace(/(^|\n)[ \t]*('use strict'|"use strict");?\s*/g, '$1'); 
    }}))
    .pipe(concat.header('(function(window, document, undefined) {\n\'use strict\';\n'))
    .pipe(concat.footer('\n})(window, document);\n'))
    .pipe(gulp.dest('dist'));
});

Alternatively, you can use the bundled helper to concatenate scripts

var concat = require('gulp-concat-util');
 
gulp.task('concat:dist', function() {
  gulp.src('scripts/{,*/}*.js')
    .pipe(concat.scripts(pkg.name + '.js'))
    .pipe(gulp.dest('dist'));
});

Options

  • Separator to use between concatenated files.
  • Default: require('os').EOL
  • Alias: newLine
