locator-yui
YUI modules compiler for locator.
This component can be integrated with Locator component from Yahoo! to shift YUI' modules and generate YUI Loader metadata. The compiled modules could be used on the server and client thru express-yui
.
Installation
Install using npm:
$ npm install locator-yui
By installing the module in your express application folder, you should be able to use it thru Locator.
Usage
Integration with locator
You can create an instance of the plugin and plug it into the locator instance, and locator will be able to analyze every file in your express app, and it will analyze any *.js
or *.json
, trying to shift them using shifter to generate the production version of those modules. It also generate metadata for YUI Loader, this metadata comes in two flavors, bundleObj.yui.server
and bundleObj.yui.client
, and these two structures will hold the modules
structure that you can pass into YUI Loader to load those in corresponding runtime.
It also generate a meta module into the filesystem, this metada is denotated by loader-<bundle-name>
as the module name, and it can be loaded from the client side as part of the YUI core collection to provision the modules
information into the loader to load any of the compiled modules.
The example below describes how to use the plugin with locator:
var Locator = require('locator'),
LocatorYUI = require('locator-yui'),
loc = new Locator();
// using locator-yui plugin
loc.plug(new LocatorYUI());
// walking the filesystem for an express app
loc.parseBundle(__dirname, {});
Integration with express
and express-yui
You can try a working example here:
https://github.com/yahoo/locator-yui/tree/master/example/express-yui
This example explores how to use locator-yui
on the server side with express
and express-yui
, while using yui
on the client side as a medium to load the compiled modules on demand.
Configuration
A configuration object can be passed into the constructure to tweak the way the plugin works.
Properties that may be used include:
cache
- Whether or not the shifting process should be cached to speed up the build process. By default, it is true.args
- array with custom shifter cli arguments. This will overrule customoptions
that are translated into shifter arguments.lint
- to enable linting in shifter.coverage
- to generate-coverage.js
version of modules in shifter.silent
- to run shifter in silent mode.quiet
- to run shifter in quiet mode.cssproc
- loaderbase
value to preprocess css to readjust urls for assets to resolve withbase
for the corresponding bundle build directory to make them work with combo.filter
- regex or function to execute for eachevt.files
. If nofilter
is supplied, all modified files will be shifted.
Here is an example:
// using locator-yui plugin
loc.plug(new LocatorYUI({
lint: true,
cssproc: "http://company-cdn.com/path/to/locator/build/folder"
}));
Compiling to YUI modules for client side
Optionally, if you plan to use the templates on the client side, you can specify format: "yui"
, and any yui template will be accessible thru YUI as a regular yui module. Here is an example of how to use them from the client side:
<script src="http://yui.yahooapis.com/3.12.0/build/yui/yui-debug.js"></script>
<script src="/static/path/to/locator/build/folder/<package-name>-<version>/loader-<package-name>.js"></script>
<script>
YUI.Env.core.push('loader-<package-name>'); // making the meta module part of the yui core
YUI({
"groups": {
"<package-name>": {
base: "/static/path/to/locator/build/folder/"
}
}
}).use('any-module-in-my-app', 'compiled-by-locator-yui', function (Y) {
// and that it all!
});
</script>
In the example above, the <package-name>
is the package name specified in the package.json
for the npm package that contains the template, which is usually the express application, the same for <version>
. Then, the configuring the <package-name>
as a custom group of modules, specifying from where those modules should be loaded, and using the meta module that was added to YUI.Env.core
to take care of the dependencies, requirements, lang, assets, etc.
