Streamlined resource transformations configured in html.


First, install gulp-pipemin as a development dependency: ```shell npm install --save-dev gulp-pipemin ``` Then, add it to your gulpfile.js: ```javascript 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')
css: function (stream, concat) {
return stream
html: function (stream) {
return stream
.pipe(minifyHtml({empty: true}));
js: function (stream, concat) {
return stream
}); ```



Blocks are expressed as: ```html ... HTML Markup, list of script / link tags. ```
  • 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): ```html ```



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.


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.


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.


Type: Boolean Default: false Show paths of all files passed to assets stream in console.


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