The JavaScript Aggregator is an OSGi servlet that provides aggregation and code minification services to AMDs loaders that supports the loader extension API. Features include:
- JavaScript minification using the Google Closure compiler
- Code trimming using has.js feature detection
- Require list expansion to reduce the cascade of requests resulting from dependency discovery as modules are loaded on the client
- CSS Optimizations
- i18n resource consolidation
- Caching of previously built/minified output for quicker response on subsequent requests
The Aggregator supports the Eclipse plugin extension architecture to allow the addition of support for:
- New types of resource repository locations on the server
- New types of module builders/minifiers
- New AMD loaders

UPGRADING
1.3.0
Major changes since 1.2 can be found at [What's new in Version 1.3] (https://github.com/OpenNTF/JavascriptAggregator/wiki/What%27s-new-in-Version-1.3).
There are some interface changes affecting resource factories. See the above link
for details. Some extensions may need to be updated and re-compiled in order to
run using the new interfaces.
1.2.0
This is a major upgrade. Read what it brings.
We've created a new bundle, jaggr-core, to house all non-osgi specific code.
This is now where the vast majority of jaggr code is located. Bundle
dependencies may need to be updated.
Besides the name changes, there are some interface changes affecting aggregator extensions. Extensions developed for previous versions of the aggregator won't run on 1.2 without changes.
Developers running from within eclipse should use a java7 jre/jdk for development and running the bundles out of the eclipse workspace. Maven will generate java6 compatible jars from the command line.
1.1.8
The changes described below don't affect casual users. Only implementors of JAGGR extensions that deal with calculation of expanded dependencies are affected:
- com.ibm.jaggr.service.deps.IDependencies.getExpandedDependencies() has been removed. Use com.ibm.jaggr.service.util.DependencyList instead.
- com.ibm.jaggr.service.util.DependencyList constructor arguments have changed.
1.1.1
- Resources defined in the server-side amd config file that use a "namedbundleresource" scheme url should leave the authority section of the uri blank and have the bundle name be the first segment in the path. (ex: namedbundleresource:///bundle.name/path/to/file)
- Interface change in IResource (added IResource resolve(String relative);) will affect any third-party resource providers.
