basic key value store without auth. has a getter and setter for different keys and a wait which will long poll for changes on root.
the server is a very basic express server (which also serves the client code for convenience).
GET /:key? - returns the value of the whole store or just for a given key
POST /:key (JSON body is the value to set) - sets the value for the key
GET /wait/:key? - returns once key changes (if provided) or any key changes (of no key is passed)
GET /client.js - the browser client is served here for convenience
import the client via script tag or module.
const L = logger('http://127.0.0.1:3000');
L.set(k, v).then(noop);
L.get(k).then((o) => console.log(o));
L.onChange(onDataCb, onErrorCb, optionalKey);
