Replaces references to non-optimized scripts or stylesheets into a set of HTML files (or any templates/views).
npm install gulp-usemin
> Deprecated. Please use Browserify or Webpack
This task is designed for gulp >= 3 and node >= 4.0.
> Attention: v0.3.0 options is not compatible with v0.2.0.
First, install gulp-usemin as a development dependency:
``shell`
npm install --save-dev gulp-usemin
Then, add it to your gulpfile.js:
`javascript
var usemin = require('gulp-usemin');
var uglify = require('gulp-uglify');
var htmlmin = require('gulp-htmlmin');
var cleanCss = require('gulp-clean-css');
var rev = require('gulp-rev');
gulp.task('usemin', function() {
return gulp.src('./*.html')
.pipe(usemin({
css: [ rev() ],
html: [ htmlmin({ collapseWhitespace: true }) ],
js: [ uglify(), rev() ],
inlinejs: [ uglify() ],
inlinecss: [ cleanCss(), 'concat' ]
}))
.pipe(gulp.dest('build/'));
});
`
If you need to call the same pipeline twice, you need to define each task as a function that returns the stream object that should be used.
`javascript`
gulp.task('usemin', function() {
return gulp.src('./*.html')
.pipe(usemin({
css: [ rev ],
html: [ function () {return htmlmin({ collapseWhitespace: true });} ],
js: [ uglify, rev ],
inlinejs: [ uglify ],
inlinecss: [ cleanCss, 'concat' ]
}))
.pipe(gulp.dest('build/'));
});
`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:
`html
`
#### 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: Array
If exist used for modify files. If does not contain string 'concat', then it added as first member of pipeline
#### outputRelativePath
Type: String
Relative location to html file for new concatenated js and css.
#### enableHtmlComment
Type: Boolean
Keep HTML comment when processing
#### jsAttributes
Type: Object
Attach HTML attributes to the output js file.
For Example :
`js`
gulp.task('usemin', function() {
return gulp.src('./index.html')
.pipe(usemin({
html: [],
jsAttributes : {
async : true,
lorem : 'ipsum',
seq : [1, 2, 1]
},
js: [ ],
js1:[ ],
js2:[ ]
}))
.pipe(gulp.dest('./'));
});
Will give you :html`
As your built script tag.
#### skipMissingResources
Type: Boolean
Allows missing resources to be skipped, instead of throwing an error.
`
|
+- 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:
`
`
We want our files to be generated in the dist directory. gulpfile.js should contain the following block:
`javascript`
gulp.task('usemin', function () {
return gulp.src('./app/index.html')
.pipe(usemin({
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:
