Super simple to use

import * as bonjour from 'axis-discovery-bonjour';

const discovery = new bonjour.Discovery();

discovery.on('hello', (device: bonjour.Device) => {
    console.log(`Hello from ${device.address}`);
});

discovery.on('goodbye', (device: bonjour.Device) => {
    console.log(`Goodbye from ${device.address}`);
});

discovery.start();
discovery.search();

Installation

npm install axis-discovery-bonjour
# or
yarn add axis-discovery-bonjour

API

Discovery

The Discovery class is the main class in the package. With it you can register for changes to cameras on the network and respond accordingly when a camera is found on, or intentionally disconnects from, the network.

class Discovery implements EventEmitter {
    /**
     * Start listen for device advertisements on all network interface
     * addresses.
     */
    start(): void;

    /**
     * Stop listening for device advertisements.
     */
    stop(): void;

    /**
     * Triggers a new search for devices on the network.
     */
    search(): void;

    /**
     * Adds the listener function to the end of the listeners array for the event named eventName.
     * No checks are made to see if the listener has already been added. Multiple calls passing the
     * same combination of eventName and listener will result in the listener being added, and
     * called, multiple times.
     * @param eventName The name of the event.
     * @param listener The callback function.
     */
    on(eventName: 'hello' | 'goodbye', listener: (device: Device) => void): this;

    // The remaining implementation of EventEmitter has been removed for brevity
}

Device

The Device class is a immutable description of a camera on the network.

/**
 * Class describing a device on the network.
 */
class Device {
    /**
     * Gets the address.
     */
    readonly address: string;

    /**
     * Gets the link local address.
     * For more information regarding link local addresses, please see
     * [Wikipedia]{@link https://wikipedia.org/wiki/Link-local_address}.
     */
    readonly linkLocalAddress: string;

    /**
     * Gets the port.
     */
    readonly port: number;

    /**
     * Gets the MAC address. In most situations this is identical to the
     * serial number. The exceptions are the Axis products which bundle
     * multiple physical devices into a single casing with a shared network
     * interface. Because of the shared network interface they also share
     * the same MAC address.
     */
    readonly macAddress: string;

    /**
     * Gets the short description for the end user.
     */
    readonly friendlyName: string;
}
