1npm install aedes-cached-persistence --save

Provided methods

Implement another persistence

Inheritance

In order to reuse aedes-cached-persistence, you need to:

1const CachedPersistence = require('aedes-cached-persistence')
2
3// if you need http://npm.im/aedes-packet, it is available
4// from this module as well
5// const { Packet } = CachedPersistence
6
7class MyPersistence extends CachedPersistence {
8    constructor(opts) {
9       super(opts)
10    }
11    addSubscriptions(client, subs, cb) {
12        // ..persistence specific implementation..
13        // call super._addedSubscriptions when you are done
14        super._addedSubscriptions(client, subs.map(mapSub), cb)
15    }
16    removeSubscriptions(client, subs, cb) {
17        // ..persistence specific implementation..
18        // call super._removedSubscriptions when you are done
19        super._removedSubscriptions(client, subs.map(mapSub), cb)
20    }
21}
22
23function mapSub (sub) {
24  return { topic: sub.topic }
25}

Tests

A persistence needs to pass all tests defined in ./abstract.js. You can import and use that test suite in the following manner:

1const test = require('node:test')
2const myperst = require('./')
3const abs = require('aedes-cached-persistence/abstract')
4
5abs({
6  test: test,
7  persistence: myperst
8})

If you require some async stuff before returning, a callback is also supported:

1const test = require('node:test')
2const myperst = require('./')
3const abs = require('aedes-persistence/abstract')
4const clean = require('./clean') // invented module
5
6abs({
7  test: test,
8  buildEmitter: require('mymqemitter'), // optional
9  persistence: function build (cb) {
10    clean(function (err) {
11      cb(err, myperst())
12    })
13  }
14})
