PhoneDB

PhoneDB is a database backed by Redis to store user contact lists. It allows you to easily find which of a user's contacts are also registered with your app. PhoneDB validates phone numbers before they are added.

Installation

If you are using yarn:

yarn add phonedb

or npm:

npm install phonedb --save

Run Redis server:

redis-server

Check out Redis quickstart to install.

Usage

Require PhoneDB:

const PhoneDB = require('phonedb');

Initialize PhoneDB, connecting to a Redis client:

const phoneDB = new PhoneDB(redisClient);

Register a user's phone number with PhoneDB:

phoneDB.register('[phone]');

Add a user's contacts:

const result = await phoneDB.addContacts(userId, ['[phone]', '[phone]']);
// 2

Get a user's contacts:

const contacts = await phoneDB.getContacts(userId);

Get a user's contacts who are also registered with PhoneDB (set registered = true):

const registeredContacts = await phoneDB.getContacts(userId, true);

Get mutual contacts between two users:

const mutualContacts = await phoneDB.getMutualContacts(userId, otherUserId);

Get mutual contacts between two users who are registered:

const mutualRegisteredContacts = await phoneDB.getMutualContacts(userId, otherUserId, true);
