Important notes for existing users
v5.0.0 (07/2023)- Removes support for all end of life node versions (v12 and v14), and now supports node v18 and v20.
- Completely rewritten in Typescript 🚀.
- When creating
MqttClient
instancenew
is now required.
v4.0.0 (Released 04/2020) removes support for all end of life node versions, and now supports node v12 and v14. It also adds improvements to debug logging, along with some feature additions.
As a breaking change, by default a error handler is built into the MQTT.js client, so if any errors are emitted and the user has not created an event handler on the client for errors, the client will not break as a result of unhandled errors. Additionally, typical TLS errors like
ECONNREFUSED
, ECONNRESET
have been
added to a list of TLS errors that will be emitted from the MQTT.js client, and so can be handled as connection errors.v3.0.0 adds support for MQTT 5, support for node v10.x, and many fixes to improve reliability.
Note: MQTT v5 support is experimental as it has not been implemented by brokers yet.
v2.0.0 removes support for node v0.8, v0.10 and v0.12, and it is 3x faster in sending packets. It also removes all the deprecated functionality in v1.0.0, mainly
mqtt.createConnection
and mqtt.Server
. From v2.0.0,
subscriptions are restored upon reconnection if clean: true
.
v1.x.x is now in LTS, and it will keep being supported as long as
there are v0.8, v0.10 and v0.12 users.As a breaking change, the
encoding
option in the old client is
removed, and now everything is UTF-8 with the exception of the
password
in the CONNECT message and payload
in the PUBLISH message,
which are Buffer
.Another breaking change is that MQTT.js now defaults to MQTT v3.1.1, so to support old brokers, please read the client options doc.
v1.0.0 improves the overall architecture of the project, which is now split into three components: MQTT.js keeps the Client, mqtt-connection includes the barebone Connection code for server-side usage, and mqtt-packet includes the protocol parser and generator. The new Client improves performance by a 30% factor, embeds Websocket support (MOWS is now deprecated), and it has a better support for QoS 1 and 2. The previous API is still supported but deprecated, as such, it is not documented in this README.
Installation
npm install mqtt --save
Example
For the sake of simplicity, let's put the subscriber and the publisher in the same file:const mqtt = require("mqtt");
const client = mqtt.connect("mqtt://test.mosquitto.org");
client.on("connect", () => {
client.subscribe("presence", (err) => {
if (!err) {
client.publish("presence", "Hello mqtt");
}
});
});
client.on("message", (topic, message) => {
// message is Buffer
console.log(message.toString());
client.end();
});
output:
Hello mqtt
React Native
MQTT.js can be used in React Native applications. To use it, see the React Native exampleIf you want to run your own MQTT broker, you can use Mosquitto or Aedes-cli, and launch it.
You can also use a test instance: test.mosquitto.org.
If you do not want to install a separate broker, you can try using the Aedes.
Import styles
CommonJS (Require)
const mqtt = require("mqtt") // require mqtt
const client = mqtt.connect("mqtt://test.mosquitto.org") // create a client
ES6 Modules (Import)
Default import
import mqtt from "mqtt"; // import namespace "mqtt"
let client = mqtt.connect("mqtt://test.mosquitto.org"); // create a client
Importing individual components
import { connect } from "mqtt"; // import connect from mqtt
let client = connect("mqtt://test.mosquitto.org"); // create a client
Command Line Tools
MQTT.js bundles a command to interact with a broker. In order to have it available on your path, you should install MQTT.js globally:npm install mqtt -g
Then, on one terminal
mqtt sub -t 'hello' -h 'test.mosquitto.org' -v
On another
mqtt pub -t 'hello' -h 'test.mosquitto.org' -m 'from MQTT.js'
See
mqtt help <command>
for the command help.Debug Logs
MQTT.js uses the debug package for debugging purposes. To enable debug logs, add the following environment variable on runtime :# (example using PowerShell, the VS Code default)
$env:DEBUG='mqttjs*'
About Reconnection
An important part of any websocket connection is what to do when a connection drops off and the client needs to reconnect. MQTT has built-in reconnection support that can be configured to behave in ways that suit the application.Refresh Authentication Options / Signed Urls with transformWsUrl
(Websocket Only)
When an mqtt connection drops and needs to reconnect, it's common to require
that any authentication associated with the connection is kept current with
the underlying auth mechanism. For instance some applications may pass an auth
token with connection options on the initial connection, while other cloud
services may require a url be signed with each connection.By the time the reconnect happens in the application lifecycle, the original auth data may have expired.
To address this we can use a hook called
transformWsUrl
to manipulate
either of the connection url or the client options at the time of a reconnect.Example (update clientId & username on each reconnect):
const transformWsUrl = (url, options, client) => {
client.options.username = `token=${this.get_current_auth_token()}`;
client.options.clientId = `${this.get_updated_clientId()}`;
return `${this.get_signed_cloud_url(url)}`;
}
const connection = await mqtt.connectAsync(<wss url>, {
...,
transformWsUrl: transformUrl,
});
Now every time a new WebSocket connection is opened (hopefully not too often), we will get a fresh signed url or fresh auth token data.
Note: Currently this hook does not support promises, meaning that in order to use the latest auth token, you must have some outside mechanism running that handles application-level authentication refreshing so that the websocket connection can simply grab the latest valid token or signed url.
Customize Websockets with createWebsocket
(Websocket Only)
When you need to add a custom websocket subprotocol or header to open a connection
through a proxy with custom authentication this callback allows you to create your own
instance of a websocket which will be used in the mqtt client.const createWebsocket = (url, websocketSubProtocols, options) => {
const subProtocols = [
websocketSubProtocols[0],
'myCustomSubprotocolOrOAuthToken',
]
return new WebSocket(url, subProtocols)
}
const client = await mqtt.connectAsync(<wss url>, {
...,
createWebsocket: createWebsocket,
});
Enabling Reconnection with reconnectPeriod
option
To ensure that the mqtt client automatically tries to reconnect when the
connection is dropped, you must set the client option reconnectPeriod
to a
value greater than 0. A value of 0 will disable reconnection and then terminate
the final connection when it drops.The default value is 1000 ms which means it will try to reconnect 1 second after losing the connection.
About Topic Alias Management
Enabling automatic Topic Alias using
If the client sets the optionautoUseTopicAlias:true
then MQTT.js uses existing topic alias automatically.example scenario:
1. PUBLISH topic:'t1', ta:1 (register)
2. PUBLISH topic:'t1' -> topic:'', ta:1 (auto use existing map entry)
3. PUBLISH topic:'t2', ta:1 (register overwrite)
4. PUBLISH topic:'t2' -> topic:'', ta:1 (auto use existing map entry based on the receent map)
5. PUBLISH topic:'t1' (t1 is no longer mapped to ta:1)
User doesn't need to manage which topic is mapped to which topic alias. If the user want to register topic alias, then publish topic with topic alias. If the user want to use topic alias, then publish topic without topic alias. If there is a mapped topic alias then added it as a property and update the topic to empty string.
Enabling automatic Topic Alias assign
If the client sets the optionautoAssignTopicAlias:true
then MQTT.js uses existing topic alias automatically.
If no topic alias exists, then assign a new vacant topic alias automatically. If topic alias is fully used, then LRU(Least Recently Used) topic-alias entry is overwritten.example scenario:
The broker returns CONNACK (TopicAliasMaximum:3)
1. PUBLISH topic:'t1' -> 't1', ta:1 (auto assign t1:1 and register)
2. PUBLISH topic:'t1' -> '' , ta:1 (auto use existing map entry)
3. PUBLISH topic:'t2' -> 't2', ta:2 (auto assign t1:2 and register. 2 was vacant)
4. PUBLISH topic:'t3' -> 't3', ta:3 (auto assign t1:3 and register. 3 was vacant)
5. PUBLISH topic:'t4' -> 't4', ta:1 (LRU entry is overwritten)
Also user can manually register topic-alias pair using PUBLISH topic:'some', ta:X. It works well with automatic topic alias assign.

mqtt.connect(url, options)
Connects to the broker specified by the given url and options and returns a Client.The URL can be on the following protocols: 'mqtt', 'mqtts', 'tcp', 'tls', 'ws', 'wss', 'wxs', 'alis'. The URL can also be an object as returned by
URL.parse()
,
in that case the two objects are merged, i.e. you can pass a single
object with both the URL and the connect options.You can also specify a
servers
options with content: `{ host:
'localhost', port: 1883 }, ... `, in that case that array is iterated
at every connect.For all MQTT-related options, see the Client constructor.
connectAsync(url, options)
Asynchronous wrapper around theconnect
function.Returns a
Promise
that resolves to a mqtt.Client
instance when the client
fires a 'connect'
or 'end'
event, or rejects with an error if the 'error'
is fired.Note that the
manualConnect
option will cause the promise returned by this
function to never resolve or reject as the underlying client never fires any
events.mqtt.Client(streamBuilder, options)
TheClient
class wraps a client connection to an
MQTT broker over an arbitrary transport method (TCP, TLS,
WebSocket, ecc).
Client
is an EventEmitter that has it's own eventsClient
automatically handles the following:- Regular server pings

: custom messageId provider. when new UniqueMessageIdProvider()
is set, then non conflict messageId is provided.
- log
: custom log function. Default uses debug package.
- manualConnect
: prevents the constructor to call connect
. In this case after the mqtt.connect

or native
In case mqtts (mqtt over tls) is required, the
options
object is passed through to tls.connect()
. If using a self-signed certificate, set rejectUnauthorized: false
. However, be cautious as this exposes you to potential man in the middle attacks and isn't recommended for production.For those supporting multiple TLS protocols on a single port, like MQTTS and MQTT over WSS, utilize the
ALPNProtocols
option. This lets you define the Application Layer Protocol Negotiation (ALPN) protocol. You can set ALPNProtocols
as a string array, Buffer, or Uint8Array based on your setup.If you are connecting to a broker that supports only MQTT 3.1 (not 3.1.1 compliant), you should pass these additional options:
{
protocolId: 'MQIsdp',
protocolVersion: 3
}
This is confirmed on RabbitMQ 3.2.4, and on Mosquitto < 1.3. Mosquitto version 1.3 and 1.4 works fine without those.

!IMPORTANT The only protocol supported in browsers is MQTT over WebSockets, so you must usews://
orwss://
protocols.
While the ws module is used in NodeJS, WebSocket is used in browsers. This is totally transparent to users except for the following:
- The
wsOption
is not supported in browsers. - Browsers doesn't allow to catch many WebSocket errors for security reasons as:
> Access to this information could allow a malicious Web page to gain information about your network, so they require browsers report all connection-time errors in an indistinguishable way.
So listening for
client.on('error')
may not catch all the errors you would get in NodeJS env.Bundle
MQTT.js is bundled using esbuild. It is tested working with all bundlers like Webpack, Vite and React.You can find all mqtt bundles versions in
dist
folder:mqtt.js
- iife format, not minifiedmqtt.min.js
- iife format, minifiedmqtt.esm.js
- esm format minified
Starting from MQTT.js > 5.2.0 you can import mqtt in your code like this:
import mqtt from 'mqtt'
This will be automatically handled by your bundler.
Otherwise you can choose to use a specific bundle like:
import * as mqtt from 'mqtt/dist/mqtt'
import * as mqtt from 'mqtt/dist/mqtt.min'
import mqtt from 'mqtt/dist/mqtt.esm'
Via CDN
The MQTT.js bundle is available through , specifically at . See for the full documentation on version ranges.About QoS
Here is how QoS works:- QoS 0 : received at most once : The packet is sent, and that's it. There is no validation about whether it has been received.
- QoS 1 : received at least once : The packet is sent and stored as long as the client has not received a confirmation from the server. MQTT ensures that it will be received, but there can be duplicates.
- QoS 2 : received exactly once : Same as QoS 1 but there is no duplicates.
About data consumption, obviously, QoS 2 > QoS 1 > QoS 0, if that's a concern to you.
Usage with TypeScript
Starting from v5 this project is written in TypeScript and the type definitions are included in the package.Example:
import { connect } from "mqtt"
const client = connect('mqtt://test.mosquitto.org')
WeChat and Ali Mini Program support
