Store and retrieve data using MQTT keypaths. You can set values, then query for values that match a wildcard. Or set values with wildcards and find all wildcards that match a simple topic.
npm install mqtt-store --save
var MQTTStore = require("mqtt-store");
var store = new MQTTStore();
store.set("hello/world", "Greetings");
store.get("hello/world"); // #=> "Greetings"
store.set("foo/bar/baz", "woot");
store.set("foo/bar", "woot wooo");
store.query("foo/#"); // #=> ["woot", "woot woo"]
store.set("fizz/#", "lolwat");
store.set("fizz/buzz/+", "neat");
store.match("fizz/buzz/quix"); // #=> ["lolwat", "neat"]There is no configuration for the store currently, can be called either with new or just as a function.
Sets a value in the store. In the background the topic will get split up into a path and will build up a tree. Set a key to undefined to essentially "unset" it. Topics with wildcards get set as through the wildcard was a literal key.
Gets a single value from the store that was set at the given topic. If nothing was set at this topic, then undefiend is returned.
Takes a topic with wildcards and returns all values that match that topic. Returns an array of values.
Takes a topic without wildcards and returns all values (that might contain wildcards) that match against that topic. Returns an array of values.
