Question
I know there are node.js libraries for Redis; what I'd like to do is run a Redis server (either on localhost or on a server host somewhere) and call it directly via HTTP (i.e. AJAX or HTTP GET as needed) from JavaScript running inside a browser (i.e. a Greasemonkey or Chrome Extension script, or maybe a bookmarklet or SCRIPT tag). Does Redis have a native REST or HTTP API?
Answer
You can't connect directly to Redis from JavaScript running in a browser because Redis does not speak HTTP. What you can do is put webdis in front of Redis, it makes it possible work with a Redis instance over a HTTP interface.
