node-unifi

Node-UniFi is a NodeJS module that allows to query/control UniFi devices via the official UniFi-Controller API. It is developed to be compatible to the UniFi-Controller API version starting with v4.x.x up to v8.x.x

Features

• Support all UniFi-Controller API features introduced with v4.x.x up to v8.x.x.
• Support CloudKey Gen1, CloudKey Gen2, UnifiOS-based UDM-Pro Controller as well as self-hostd UniFi controller software.
• Returns all data in well-defined JSON parsable strings/objects.
• Use of modern axios-based nodejs http library.
• API functions returning NodeJS Promises for modern nodejs uses via async/await or then()/catch().
• Support for WebSocket-based push notifications of UniFi controllers for listening for state/object changes using EventEmitter-based nodejs functionality.
• Usable with local and UniFI cloud accounts and with 2FA authentication.

Requirements

• Installed UniFi-Controller/Network version v4 up to v8 (UDM-Pro, UDM-SE, UDM, UDR, UDW, CloudKey Gen1/Gen2).
• Direct network connectivity between the application using node-unifi and the host:port (normally TCP port 443 or 8443) where the UniFi controller is running on.
• Node.js version >= 16.x

Installation

node-unifi can be installed using the following npm command:

npm install node-unifi

Examples

node-unifi has been designed to be used quite straight forward and without introducing ackward language constructs. The following example should give a brief introduction on how to use node-unifi in your own applications using its Promises-based API interface:

const Unifi = require('node-unifi');
const unifi = new Unifi.Controller({'<HOSTNAME>', '<PORT>', sslverify: false});

(async () => {
  try {
    // LOGIN
    const loginData = await unifi.login('<USERNAME>', '<PASSWORD>');
    console.log('login: ' + loginData);

    // GET SITE STATS
    const sites = await unifi.getSitesStats();
    console.log('getSitesStats: ' + sites[0].name + ':' + sites.length);
    console.log(JSON.stringify(sites));

    // GET SITE SYSINFO
    const sysinfo = await unifi.getSiteSysinfo();
    console.log('getSiteSysinfo: ' + sysinfo.length);
    console.log(JSON.stringify(sysinfo));

    // GET CLIENT DEVICES
    const clientData = await unifi.getClientDevices();
    console.log('getClientDevices: ' + clientData.length);
    console.log(JSON.stringify(clientData));

    // GET ALL USERS EVER CONNECTED
    const usersData = await unifi.getAllUsers();
    console.log('getAllUsers: ' + usersData.length);
    console.log(JSON.stringify(usersData));

    // LOGOUT
    const logoutData = await unifi.logout();
    console.log('logout: ' + JSON.stringify(logoutData));
  } catch (error) {
    console.log('ERROR: ' + error);
  }
})();

Please note that every unifi.XXXXX() function returns a Promise, thus async/await as well as .then()/.catch() can be used accordingly.

Event-Emitter WebSockets Interface

Since version 2.0.0 node-unifi supports (thanks to unifi-axios-events) the WebSocket interface of a UniFi controller. This new interface allows to listen for events using unifi.listen() and automatically receive events as soon as the UniFi controller sends them out via its WebSocket functionality. For receiving these events in a nodejs-compatible way node-unifi uses internally EventEmitter2 which allows to execute actions based on event filters defined by unifi.on(...).

An example on how to use this EventEmitter-based functionality of node-unifi to immediately receive state changes rather than regularly having to poll a unifi controller for changes can be seen here:

const Unifi = require('node-unifi');
const unifi = new Unifi.Controller({'<HOSTNAME>', '<PORT>', sslverify: false});

(async () => {
  try {
    // LOGIN
    const loginData = await unifi.login('<USERNAME>', '<PASSWORD>');
    console.log('login: ' + loginData);

    // LISTEN for WebSocket events
    const listenData = await unifi.listen();
    console.log('listen: ' + listenData);

    // Listen for alert.client_connected
    unifi.on('alert.client_connected', function (data) {
      const ts = new Date(data[0].timestamp).toISOString();
      console.log(`${ts} - ${this.event}: ${data[0].parameters.CLIENT.id} (${data[0].parameters.CLIENT.name})`);
    });

    // Listen for alert.client_disconnected
    unifi.on('alert.client_disconnected', function (data) {
      const ts = new Date(data[0].timestamp).toISOString();
      console.log(`${ts} - ${this.event}: ${data[0].parameters.CLIENT.id} (${data[0].parameters.CLIENT.name})`);
    });

    // Listen for ctrl.* events
    unifi.on('ctrl.*', function () {
      console.log(`${this.event}`);
    });
  } catch (error) {
    console.log('ERROR: ' + error);
  }
})();

Moving from v1 of node-unifi to v2+

If you are having an application still using the obsolete v1 version of node-unifi and you want to port it to using the new/revised v2 version, all you have to do is:

• make sure your application can deal with NodeJS Promises as all node-unifi API functions return proper Promises allowing to use async/await or .then()/.catch() logic for synchronous processing of events (see Examples) rather than expecting callback functions, forcing you to nest them properly.
• eliminate the previously necessary site function argument required when calling a node-unifi function. Now you can either use the { site: 'my site' } argument when passing contructor options to node-unifi or you switch to a different site using unifi.opts.site='my site' before calling a node-unifi API function.
• as the API functions had been changed to work on a single site only, make sure your app is changed so that it expects a single site JSON return dataset only.
• The new version by default verifies SSL connections and certificates. To restore the behaviour of the old version set sslverify: false in the constructor options
