bundledom

bundledom -- bundle assets of an html document

New in version 3: uses rollup for bundling, and still supports old-style bundling.

Features

• recursively concatenate scripts, styles, and link[rel=import]
• minify scripts and stylesheets
• vendor autoprefixing of stylesheets, configurable through env, see https://github.com/ai/browserslist
• bundle everything in one single js file, or split in js / css.
• prepend or append additional scripts, styles, or imports
• exclude or ignore a tag by matching a url substring new in version 1.8.0: or a minimatch pattern with wildcard (see example below)
• modify the DOM and outputs html
• downloads remote scripts or stylesheets with whitelist (new in 1.7.0)
• allows custom asynchronous DOM modifications (new in 1.6.0)
• any kind of modules are supported, thanks to rollup

Install

npm install -g bundledom

Usage

This saves modified html file, and styles are bundled into js file:

bundledom 
--html bundles/index.html
--js /bundles/index.js
-x jquery.js -x moment.js -i index.js
--prepend '/js/HTMLImports.js'
public/index.html

This saves styles separately:

bundledom 
--html bundles/index.html
--css /bundles/index.css
--js /bundles/index.js
--exclude jquery.js 
--prepend '/js/HTMLImports.js'
public/index.html

This does not compress files, and specifies root dir

bundledom
--concatenate
--html bundles/index.html
--css /bundles/index.css
--js /bundles/index.js
--exclude jquery.js 
--prepend '/js/HTMLImports.js'
--root public
public/templates/index.html

new in 1.6.0

bundledom-all
  --filter "**/excluded-*.*"
  --common common.html
  --suffix 1.0.0
  "templates/*.html"

it bundles common files then processes all files matching pattern and put everything with suffixes in a bundles/ directory.

See bundledom-all -h for more command-line options.

Paths are relative to the input file path.

API

bundledom(path, opts, cb)

where path is the path of the html file to process, and opts has these properties:

• exclude: array of matched strings
• ignore: array of matched strings
• append: array of strings
• prepend: array of strings
• js: path relative to html file
• css: path relative to html file
• html: path relative to root
• root: path
• custom: function(dom, opts, data) {} returning a promise
• remotes: list of allowed remote domains to download from

Strings are matched simply by searching a substring.

Tags without src or href attributes can be excluded or ignored by passing a dot ".", otherwise they are bundled.

Omitting js, css options skips the insertion of the corresponding tag in the html document.

If cb is omitted, returns a promise.

Returns an object with following properties:

• js, css, html: the resulting js, css, html
• scripts, stylesheets, imports: the lists of processed files

Compatibility of HTML Imports bundling

Anywhere createHTMLDocument works. For IE 9 to 11, works better with create-html-document-polyfill
