gulp-include

Works with gulp 3 and gulp 4

Features

• Concatenate files with full control
• Respects indentation whitespace
• Uses globs for simple path control
• Works recursively (files can include files that can include files, and so on)

Installation

 npm install gulp-include

Usage

Example gulpfile.js:

 const gulp = require('gulp')
const include = require('gulp-include')

exports.scripts = function (done) {
  gulp.src('source/js/entry.js')
    .pipe(include())
      .on('error', console.log)
    .pipe(gulp.dest('dist/js'))
}

Include directives

gulp-include uses directives similar to sprockets or snockets. A directive is a comment in your files that gulp-include recognizes as a command.

Example directives:

 //=require vendor/jquery.js
//=require vendor/**/*.js
//=include relative/path/to/file.js
//=include ./relative/path/to/file-even-when-includePaths-set.js

 /*=include relative/path/to/file.css */

 #=include relative/path/to/file.coffee

 <!--=include relative/path/to/file.html -->

The contents of the referenced file will replace the file.

require vs. include

A file that is included with require will only be included if it has not been included before. Files included with include will always be included.
For instance, let's say you want to include jquery.js only once, and before any of your other scripts in the same folder.

 //=require vendor/jquery.js
//=require vendor/*.js

Note: This also works recursively. If for instance, for the example above, if another file in the folder vendor is also including jquery.js with the require-directive it will be ignored.

Options

• extensions (optional)

  • Takes a String or an Array of extensions.
    eg: "js" or ["js", "coffee"]
  • If set, all directives that does not match the extension(s) will be ignored

• includePaths (optional)

  • Takes a String or an Array of paths.
    eg: __dirname + "/node_modules" or [__dirname + "/assets/js", __dirname + "/bower_components"]
  • If set, gulp-include will use these folders as base path when searching for files.
  • If set, you can still include files relative to the current file by pre-pending includes with ./.

• hardFail (optional)

  • Boolean, false by default
  • Set this to true if you want gulp-include to throw errors if a file does not match
    an include directive.
  • If set to false gulp include will not fail, but display warnings in the console.

• separateInputs (optional)

  • Boolean, false by default
  • Set this to true to allow each input file to use require-directives independently.
  • Useful if you are referencing several paths in gulp.src and need them to require the same files.

Example options usage:

 gulp.src('src/js/main.js')
  .pipe(include({
    extensions: 'js',
    hardFail: true,
    separateInputs: true,
    includePaths: [
      __dirname + '/bower_components',
      __dirname + '/src/js'
    ]
  }))
  .pipe(gulp.dest('dist/js'))
