Increments

Implements distributed counters (eg. likes, views) across a group of shards in a collection. Note this is for managing a count at a collection level.

First configure firebase and create a firestore instance...

require('dotenv').config();

var firebase = require("firebase-admin");

firebase.initializeApp({
  credential: firebase.credential.cert({
  	"projectId":process.env.FIREBASE_PROJECT_ID,
    "private_key": process.env.FIREBASE_PRIVATE_KEY.replace(/\\n/g, '\n'),
    "client_email": process.env.FIREBASE_CLIENT_EMAIL,
  }),
  databaseURL: process.env.FIREBASE_URL
});

var db = firebase.firestore();

Next increment a counter on a collection

const firebaseUtil = require('fire-ace-of-base');
firebaseUtil.increment(db,'collection-name');

Optional define the # of shards (default is 20)

var shardCount = 100;
const firebaseUtil = require('fire-ace-of-base');
firebaseUtil.increment(db,'collection-name',shardCount);

Logs

For maintaining an array of events (eg. session activity) across a collection of shards.

First configure firebase and create a firestore instance...

require('dotenv').config();

var firebase = require("firebase-admin");

firebase.initializeApp({
  credential: firebase.credential.cert({
  	"projectId":process.env.FIREBASE_PROJECT_ID,
    "private_key": process.env.FIREBASE_PRIVATE_KEY.replace(/\\n/g, '\n'),
    "client_email": process.env.FIREBASE_CLIENT_EMAIL,
  }),
  databaseURL: process.env.FIREBASE_URL
});

var db = firebase.firestore();

Next log an event to a session inside the sessions collection

const firebaseUtil = require('fire-ace-of-base');
var json = {} // any json data you want to append to the 'events' array for the session.
firebaseUtil.log(db,'sessions','session-unique-id',json);

Optional define the # of shards (default is 5)

var shardCount = 100;
const firebaseUtil = require('fire-ace-of-base');
firebaseUtil.log(db,'sessions','session-unique-id',shardCount);
