A Gulp Pipeline for minifying Javascript

pipeline-minify-js

Information

Package	Description	Version
pipeline-minify-js	This pipeline minifies and optionally concatenates js files	1.0.0

Overview

Gulp pipeline for minifiying JS and optionally concatenating the output.

Install

npm install pipeline-minify-js --save-dev

Usage

var gulp = require('gulp');
var minifyPipeline = require('pipeline-minify-js');


gulp.task('default', function() {
  return gulp
    .src(['src/**/*.js'])
    .pipe(minifyPipeline.minifyJS());
});

Options

Pipeline options:

• config -> Object that contains the configuration.

  • addSourceMaps: If set to false source maps won't be generated for the compile files. By default the pipeline will generate the source maps and store them next to the original file, with .map extension.

  • concat: If false the pipeline won't concatenate the files into a single generated file

  • concatFilename: Sets the filename of the concatenated files.

  • concatOutput: Sets the path to where the sourcemaps are written to; set to next to reference file, by default. If wanted to have a separate folder for map files, just change this to a desire folder name.

  • uglify: Uglifies JS files using the basic gulp-uglify configuration.

  Default:

  config = {
    addSourceMaps: true,
    concat: true,
    concatFilename: '{package-name}.min.js',
    concatOutput: './',
    uglify: {}  //default options
  }

when passing options use the following format:

gulp.task('default', function() {
  return gulp
    .src(['src/**/*.js'])
    .pipe(minifyPipeline.minifyJS({ addSourceMaps: false, concat: true,}));
});

Results

This pipeline returns an object. This object receives a stream with the files to minify, and you can call the minifyJS method to execute the minification. Based on the configuration provided in config.concatenate, the pipeline will concatenate the files or no. After finishing the process you will have a folder named as config.output . In this folder you can find the .min.js file, the source map, and a plain js file if the concatenation was executed.
