Firebase NodeJS Client

Compact firebase client implementation for NodeJS environment

Why do we need another module

Current official modules support only

• Node.JS as Admin with low to none client capabilities
• Browser only env (hard linked to window, IndexedDB and WebWorkers)

I needed module that I can use in any JavaScript environment. The main difference is, that you can to provide your own storage with simple get/set methods for data persistency.

Putting this public, so it can help some other projects too. Will add more parts based on my project needs or uppon request.

What is done / planned

• ✅ Web Installartions
• ⬜️ Mobile Installations
• ✅ Remote config
• ⬜️ Cloud Messaging
• ⬜️ HeartBeat
• ⬜️ TESTS - probably jest/mocha

How to use it

const fs = require('fs')
const path = require('path')
const { FirebaseApp, Installations, RemoteConfig } = require('../dist')

const storageFileName = path.join(__dirname, 'storage.json')

let store = {}

if (fs.existsSync(storageFileName)) {
    store = JSON.parse(fs.readFileSync(storageFileName).toString())
}

const app = new FirebaseApp({
    credentials: { /* CREDENTIALS HERE */ },
    storage: {
        get: (key) => store[key],
        set: (key, value) => {
            store[key] = value

            fs.writeFileSync(storageFileName, JSON.stringify(store, null, 2))
        }
    }
})

const remoteConfig = new RemoteConfig(app, {
    defaultConfig: {
        test: 'true'
    }
})

remoteConfig.on('fetch', () => {
    console.log('fetch')
})

remoteConfig.on('activate', () => {
    console.log('activate')
})

remoteConfig.fetchAndActivate().then(() => {
    console.log(remoteConfig.getAll())
})
