Default Provider
or
CDN Provider Configuration
For Webravo provider, you must define just your cdn url and specific url to upload assets. For Google Storage provider you must define the remote bucket name, the default TTL, and the storage URL to pre-pend to assets.
Optionally, you can define another bucket (cdn_bucket) to use when creating assets url, in case you handle separate buckets for upload and retrieve. If omitted, the same bucket name is used.
Bypass
To disable CDN and load your assets from local machine for testing purposes, set the bypass option to true:
Don't overwrite CDN images if source is missing
As per default, missing images are replaced by a fallback image (overwrite = true by default). To change this behaviour set overwrite to false in your configuration file.
Overwrite flag could be passed also as optional parameter to any Cdn:: call.
Check for file size changes
As per default, file size is not checked to detect image changes, but only modification date is used. To enable file size check set checksize to true in your configuration file.
Checksize flag could be passed also as optional parameter to any Cdn:: call.
Elixir assets
(Webravo provider only)
Note: the elixir works the same as the Laravel elixir it loads the manifest.json file from build folder and choose the correct file revision generated by gulp:
Note: currently, the elixir command does not copy assets to Cdn, but simply add/replace the url with the Cdn url
Test
