Would it be possible for someone to package haste-server? It is a pastebin-like server that looks pretty great. It uses NPM.
One of the things to look out for is managing the storage (check here for the developers’ instructions). haste-server supports using plain old files, Redis, Postgres, Memcached, RethinkDB and Amazon S3. It would be great if the snap supported ones that “just worked” out of the box with no (or little) modification required (kind of like with Nextcloud, which ships its own MySQL server I believe).
This is also a server, meaning that a service/daemon would make things super nice.
