Digests and compresses static files.

$ mix phx.digest

$ mix phx.digest priv/static -o /www/public

The first argument is the path where the static files are located. The
|
|
`-o` option indicates the path that will be used to save the digested and
|
|
compressed files.
|
|
|
|
If no path is given, it will use `priv/static` as the input and output path.
|
|
|
|
The output folder will contain:
|
|
|
|
* the original file
|
|
* the file compressed with gzip
|
|
* a file containing the original file name and its digest
|
|
* a compressed file containing the file name and its digest
|
|
* a cache manifest file
|
|
|
|
Example of generated files:
|
|
|
|
* app.js
|
|
* app.js.gz
|
|
* app-eb0a5b9302e8d32828d8a73f137cc8f0.js
|
|
* app-eb0a5b9302e8d32828d8a73f137cc8f0.js.gz
|
|
* cache_manifest.json
|
|
|
|
You can use `mix phx.digest.clean` to prune stale versions of the assets.
|
|
If you want to remove all produced files, run `mix phx.digest.clean --all`.

## vsn
|
|
|
|
It is possible to digest the stylesheet asset references without the query
|
|
string "?vsn=d" with the option `--no-vsn`.
