Store uploaded files with FILESTORAGE

Total.js 5 · total5@0.0.19 filesuploadstorage Executed against Total.js 5

FILESTORAGE(name) is a file store: files are saved under an id (use UID()) and served back by that id. Receive the upload with @upload, save it with file.fs(storage, id, callback) and answer downloads with $.filefs(storage, id), which sends the stored file with its content-type.

The storage name comes from the config file, so it can change per environment.
