Streaming static file server based on LevelDB
Streaming static file server based on LevelDB.
Store and serve a nice cat picture at
var Server = ;var level = ;var http = ;var fs = ;// initialize db and servervar db = ;var server = ;// store catvar ws = server;fs;// serve cathttp;console;
ETags are used to save bandwidth and reduce load.
With sublevels you can e.g. give a plugin or a user only access to a part of the database so they can't do anything harmful. The location in the sublevel tree is reflected in the resulting public url.
This concept involves two instances of
var Server = ;var level = ;var http = ;var SubLevel = ;var fs = ;// initialize the db and give it sublevelsvar db = ;;// initialize server for sublevelvar server = ;// cat from sublevel "cool"."cats" will be served at /files/cool/cats/white.pngvar ws = server;fs;// serve catvar dbServer = ;http;console;
/files/ (sublevels /) file-id

in an async api.
