gulp-pipemin

Streamlined resource transformations configured in html.

Usage

First, install gulp-pipemin as a development dependency:

npm install --save-dev gulp-pipemin

Then, add it to your gulpfile.js:

var pipemin = require('gulp-pipemin');
var uglify = require('gulp-uglify');
var minifyHtml = require('gulp-minify-html');
var minifyCss = require('gulp-minify-css');
var rev = require('gulp-rev');

gulp.task('pipemin', function () {
  return gulp.src('./*.html')
    .pipe(pipemin({
      css: function (stream, concat) {
        return stream
          .pipe(minifyCss())
          .pipe(concat);
      },
      html: function (stream) {
        return stream
          .pipe(minifyHtml({empty: true}));
      },
      js: function (stream, concat) {
        return stream
          .pipe(concat)
          .pipe(uglify())
          .pipe(rev());
      }
    }))
    .pipe(gulp.dest('build/'));
});

API

Blocks

Blocks are expressed as:

<!-- build:<pipelineId>(alternate search path) <path> -->
... HTML Markup, list of script / link tags.
<!-- endbuild -->
  • pipelineId: pipeline id for options or remove to remove a section
  • alternate search path: (optional) By default the input files are relative to the treated file. Alternate search path allows one to change that
  • path: the file path of the optimized file, the target output

An example of this in completed form can be seen below (note usage of globs):

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

<!-- build:js js/lib.js -->
<script src="../lib/angular-*-min.js"></script>
<!-- endbuild -->

<!-- build:js1 js/app.js -->
<script src="js/{app,main}.js"></script>
<script src="js/controllers/thing-controller.js"></script>
<script src="js/models/thing-model.js"></script>
<script src="js/views/thing-view.js"></script>
<!-- endbuild -->

<!-- build:remove -->
<script src="js/localhostDependencies.js"></script>
<!-- endbuild -->

Options

assetsDir

Type: String

Alternate root path for assets. New concated js and css files will be written to the path specified in the build block, relative to this path. Currently asset files are also returned in the stream.

path

Type: String

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

any pipelineId

Type: Function

If exist used for modify files. Each pipeline gets input stream and concat task, except for html. Function is called separately on demand for each block.

'other' pipelineId

Type: Function

Special pipeline for files not matched by any block, but passed to asssets stream.

assetsStream

Type: Function

Stream constructor (works with lazypipe) of assets stream. When passed, pipemin search for files requested by blocks inside this stream instead of probing filesystem. Error is returned if no such file was passed.

debugStreamFiles

Type: Boolean Default: false

Show paths of all files passed to assets stream in console.

outputRelativePath

Type: String Relative location to html file for new concatenated js and css.

Use case

|
+- app
|   +- index.html
|   +- assets
|       +- js
|          +- foo.js
|          +- bar.js
|   +- css
|       +- clear.css
|       +- main.css
+- dist

We want to optimize foo.js and bar.js into optimized.js, referenced using relative path. index.html should contain the following block:

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

    <!-- build:js js/optimized.js -->
    <script src="assets/js/foo.js"></script>
    <script src="assets/js/bar.js"></script>
    <!-- endbuild -->

We want our files to be generated in the dist directory. gulpfile.js should contain the following block:

gulp.task('pipemin', function () {
  return gulp.src('./app/index.html')
      .pipe(pipemin({
        js: [uglify()]
        // in this case css will be only concatenated (like css: ['concat']).
      }))
      .pipe(gulp.dest('dist/'));
});

This will generate the following output:

|
+- app
|   +- index.html
|   +- assets
|       +- js
|          +- foo.js
|          +- bar.js
+- dist
|   +- index.html
|   +- js
|       +- optimized.js
|   +- style.css

index.html output:

    <link rel="stylesheet" href="style.css"/>

    <script src="js/optimized.js"></script>
