CDN Support in Oracle JET

With the recent releases of Oracle JET - CDN support in your app can be enabled easily. By default JET app is set to download all JET toolkit related scripts and static files from the same host, where application is hosted. You can track it easily through network monitor, you should see such files as ojknockout.js, etc. fetched from same host:


CDN can be enabled by changing use property from local to cdn in path_mapping.json and restarting the app:


After this change, you should see all JET toolkit content to be downloaded from static.oracle.com host:


Benefit - you reduce load on your host, from where only application specific files will be downloaded, with JET toolkit code downloaded from external Oracle host. Same achievable on your own host, but JET toolkit content downloaded from Oracle host - is compressed out of the box (another benefit):
