gulp-readmin

Load files from script and link tags into a stream to do with as you wish

Usage

First, install gulp-readmin as a development dependency:

npm install --save-dev gulp-readmin

Then, add it to your gulpfile.js:

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

gulp.task('minifyjs', function () {
  return gulp.src('templates/layout.html')
      .pipe(readmin({type: 'js'))
      .pipe(uglify())
      .pipe(concat('scripts.min.js'))
      .pipe(gulp.dest('build'));
});

API

Blocks

Blocks are expressed as:

<!-- build:<pipelineId>(alternate search path) -->
... HTML Markup, list of script / link tags.
<!-- endbuild -->

• pipelineId: js or css
• alternate search path: (optional) By default the input files are relative to the treated file. Alternate search path allows one to change that

For example:

<!-- build:js -->
<script src="lib/framework.js"></script>
<script src="src/app.js"></script>
<!-- endbuild -->

Options

type

Type String

Set to js or css to filter out the other type. Default is to include both in stream.

path

Type: String

Default alternate search path for files. Can be overridden by the alternate search path option for a given block.

Use case

|
+- gulpfile.js
+- src
|   +- templates
|       +- layout.php
+- web
|   +- index.php
|   +- js
|   |   +- foo.js
|   |   +- bar.js
|   +- css
|   |   +- normalize.css
|   |   +- main.css
|   +- build

We want to optimize scripts (in the correct order) into scripts.min.js, and styles into styles.min.css. layout.php should contain the following blocks:

    <!-- build:css(web) -->
    <link rel="stylesheet" href="css/clear.css"/>
    <link rel="stylesheet" href="css/main.css"/>
    <!-- endbuild -->

    <!-- build:js(web) -->
    <script src="js/foo.js"></script>
    <script src="js/bar.js"></script>
    <!-- endbuild -->

We want our files to be generated in the web/build directory. gulpfile.js should contain the following tasks:

gulp.task('minifycss', function () {
  return gulp.src('src/templates/layout.php')
      .pipe(readmin({type:'css'}))
      .pipe(minifyCss())
      .pipe(concat('styles.min.css'))
      .pipe(gulp.dest('web/build'));
});

gulp.task('minifyjs', function () {
  return gulp.src('src/templates/layout.php')
      .pipe(readmin({type:'js'}))
      .pipe(uglify())
      .pipe(concat('scripts.min.js'))
      .pipe(gulp.dest('web/build'));
});
