Install

npm install -g @webmodule/bundle

Usage

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

webmodule-bundle
--html bundles/index.html
--js /bundles/index.js
-x jquery.js -x moment.js -i index.js
--prepend '/js/custom-elements.js'
public/index.html

This saves styles separately:

webmodule-bundle
--html bundles/index.html
--css /bundles/index.css
--js /bundles/index.js
--exclude jquery.js
--prepend '/js/custom-elements.js'
public/index.html

This does not compress files, and specifies root dir

webmodule-bundle
--concatenate
--html bundles/index.html
--css /bundles/index.css
--js /bundles/index.js
--exclude jquery.js
--prepend '/js/custom-elements.js'
--root public
public/templates/index.html

A tool to bundle a bunch of files:

webmodule-bundle-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 webmodule-bundle-all -h for more command-line options.

Paths are relative to the input file path.

API

webmoduleBundle(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: absolute mount path, defaults to current directory
• custom: function(dom, opts, data) {} returning a promise
• remotes: list of allowed remote domains to download from
• modulesPrefix: the mount path for resolving node_modules ( becomes /node_modules/xxx/index.js), defaults to "/".
• modulesRoot: where node modules are to be found. Defaults to ".".
• assets: if set, copy stylesheets assets to this path relative to root.
• analyze: boolean, get information about bundle

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, assets, imports: the lists of processed files
