Queries connected iOS devices and installs apps

node-ios-device

Queries connected iOS devices, installs apps, and relays log output.

Prerequisites

node-ios-device only works on macOS 10.11 or newer and requires N-API version 3 and the following Node.js versions:

• Node.js
  • v8.12.x or newer
  • v10.2.0 or newer

Installation

npm install node-ios-device

CLI

$ node-ios-device

USAGE: node-ios-device <command> [options]

COMMANDS:
  forward  Connects to a port on an device and relays messages
  install  Install an app on the specified device
  list     Lists connected devices
  syslog   Outputs a devices syslog messages
  watch    Listens for devices to be connected/disconnected

GLOBAL OPTIONS:
  --no-color    Disable colors
  -h,--help     Displays the help screen
  -v,--version  Outputs the version

Example

import iosDevice from 'node-ios-device';

// get all connected iOS devices
const devices = iosDevice.list();
console.log('Connected devices:', devices);

// continuously watch for devices to be connected or disconnected
const handle = iosDevice.watch();
handle.on('change', devices => {
    console.log('Connected devices:', devices);
});
handle.on('error', console.error);

// install an iOS app
iosDevice.install('<device udid>', '/path/to/my.app');
console.log('Success!');

// relay the syslog output to the console
iosDevice
    .syslog('<device udid>')
    .on('data', console.log)
    .on('end', () => console.log('Device disconnected'));

// relay output from a TCP port created by an iOS app
iosDevice
    .forward('<device udid>', 1337)
    .on('data', console.log)
    .on('end', () => console.log('Device disconnected'));

API

list()

Retrieves an array of all connected iOS devices.

Returns an Array of device objects.

Note that only devices connected via a USB cable will be returned. Devices connected via Wi-Fi will not be returned. The main reason we do this is because you can only relay the syslog from USB connected devices.

Device objects contain the following information:

• udid - The device's unique device id (e.g. "a4cbe14c0441a2bf87f397602653a4ac71eb0336")
• name - The name of the device (e.g. "My iPhone")
• buildVersion - The build version (e.g. "10B350")
• cpuArchitecture - The CPU architecture (e.g. "armv7s")
• deviceClass - The type of device (e.g. "iPhone", "iPad")
• deviceColor - The color of the device (e.g. "Black", "White")
• hardwareModel - The device module (e.g. "N41AP")
• modelNumber - The model number (e.g. "MD636")
• productType - The product type or model id (e.g. "iPhone5,1")
• productVersion - The iOS version (e.g. "6.1.4")
• serialNumber - The device serial number (e.g. "XXXXXXXXXXXX")

There is more data that could have been retrieved from the device, but the properties above seemed the most reasonable.

watch()

Continuously retrieves an array of all connected iOS devices. Whenever a device is connected or disconnected, the 'change' event is emitted.

Returns an EventEmitter-based Handle instance that contains a stop() method to discontinue tracking devices.

Event: 'change'

Emitted when a device is connected or disconnected.

• {Array<Object>} devices - An array of devices

Example:

const handle = iosDevice.watch()
    .on('change', console.log);

setTimeout(() => {
    // turn off tracking after 1 minute
    handle.stop();
}, 60000);

install(udid, appPath)

Installs an iOS app on the specified device.

• {String} udid - The device udid
• {String} appPath - The path to the iOS .app

Currently, an appPath that begins with ~ is not supported.

The appPath must resolve to an iOS .app, not the .ipa file.

syslog(udid)

Relays the syslog from the iOS device.

Starting with iOS 10, the syslog no longer contains application specific output. If you want output for a specific app, then you will need to use a TCP socket. See forward() for more info.

• {String} udid - The device udid

Returns a Handle instance that contains a stop() method to discontinue emitting messages.

NOTE: syslog() only supports USB connected devices. Wi-Fi-only connected devices will not work.

Event: 'data'

Emitted for each line of output. Empty lines are omitted.

• {String} message - The log message.

Event: 'end'

Emitted when the device is physically disconnected. Note that this does not unregister the internal callback. You must manually call handle.stop() to cleanup.

Example:

const handle = iosDevice
	.syslog('<device udid>')
    .on('data', console.log)
    .on('end', () => console.log('End of syslog'));

setTimeout(function () {
	// turn off logging after 1 minute
	handle.stop();
}, 60000);

forward(udid, port)

Relays messages from a server running on the device on the specified port.

• {String} udid - The device udid
• {String} port - The TCP port listening in the iOS app to connect to

Returns a Handle instance that contains a stop() method to discontinue emitting messages.

NOTE: forward() only supports USB connected devices. Wi-Fi-only connected devices will not work.

Event: 'data'

Emitted for each line of output. Empty lines are omitted.

• {String} message - The log message.

Event: 'end'

Emitted when the device is physically disconnected. Note that this does not unregister the internal callback. You must manually call handle.stop() to cleanup.

Example:

const handle = iosDevice
	.forward('<device udid>', 1337)
    .on('log', console.log)
    .on('end', () => console.log('End of forward'));

setTimeout(function () {
	// turn off logging after 1 minute
	handle.stop();
}, 60000);

Advanced

Debug Logging

node-ios-device exposes an event emitter that emits debug log messages. This is intended to help debug issues under the hood. The average user will never need to use this, however it would be handy when filing a bug.

iosDevice.on('log', msg => console.log(msg));

Alternatively, node-ios-device uses the amazing snooplogg debug logger where you simply set the SNOOPLOGG environment variable to node-ios-device (or *) and it will print the debug log to stdout.
