mqtt-store
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
```
Example:
```javascript var MQTTStore = require("mqtt-store"); var store = new MQTTStore(); store.set("hello/world", "Greetings"); store.get("hello/world"); // #=> {key: "hello/world", value: "Greetings"} store.set("foo/bar/baz", "woot"); store.set("foo/bar", "woot wooo"); store.findMatching("foo/#"); // #=> // {key: "foo/bar/baz", value: "woot"}, // {key: "foo/bar", value: "woot wooo"} // store.set("fizz/#", "lolwat"); store.set("fizz/buzz/+", "neat"); store.findPatterns("fizz/buzz/quix"); // #=> // {key: "fizz/#", value: "lolwat"}, // {key: "fizz/buzz/+", value: "neat"} // ```API
MQTTStore.Result(sections, value)
All results from queries are represented as a Result object.
MQTTStore.Result#key : String
The full key string for where the result was found
MQTTStore.Result#value : Any
The value stored in this result
MQTTStore.Result#sections : Array<String>
The key, split in to an array of sections
MQTTStore()
There is no configuration for the store currently, can be called either with new or just as a function.
MQTTStore#put(key : String, value : Any)
Sets a value in the store. In the background the topic will get split up into a path and will build up a tree. Topics with wildcards get set as through the wildcard was a literal key.
MQTTStore#get(key : String) : Result<Any>
Gets a single value from the store that was set at the given topic. If nothing was set at this topic, then MQTTStore.NO_RESULT is returned.
MQTTStore#.del(key : String) : Boolean
Deletes the value stored at the key if it exists. Returns true if the key contained a value, false if the key didn't exist or had no value.
