Rasta.js ACID-less anonymous public cross-domain key-value data store

Rasta.get('age', function(val){
  /* val == '100' */
})

Enter key:

key

Enter value:

val SET

Rasta.set('age','100', function(){
  /*      */
})
          

Keys and values are limited to 250 ASCII characters, excluding space, newline, ? and /

JSON-P is used for cross-domain communication

Optional second callback will be called on error

Rasta.get('some_key', function(val){
  /* use val */
}, function(){
  /* error occured */
})

Data store for static websites

Communication between front-ends

A building block

A simple, easy to implement API (just 2 endpoints):

GET /get/{key}?callback=?
and
GET /set/{key}/{val}?callback=?

Where's the data stored?

By default, my server (well, heroku at the moment). If you want to host your own, just change Rasta.url.

How much storage?

Unspecified by design. Let's say 5 MB. Old keys are invalidated. Strategy unspecified, could be LRU, LFU, etc.

Why HTTP GET for setting?

Because JSON-P doesn't support POST.

Message github.com/pitr for more questions

Wait. What's this again?

This is a key-value date store (something like Memcache or Redis) that you can access from browser's front-end (like HTML5 localStorage), except you do not host it yourself.

By simply including provided script tag, you get a tiny library that communicates with the data store. You get

1. Rasta.get(key, cb(), err()),
2. Rasta.set(key, val, cb(), err()), and
3. Rasta.url= (initialized to "http://rastajs.errorjs.com")
