Installation
Using npm:
$ npm install particle-usb @particle/device-constants
NOTE: particle-usb
declares @particle/device-constants
as a peerDependency
- this ensures your app only ever has one copy of that dependency
Usage
In Node.js:
import * as usb from 'particle-usb';
Enumerating devices
const devices = await usb.getDevices();
for (let device of devices) {
console.log(device.type); // Prints device type, e.g. "Photon"
}
Opening devices
Most of the device methods, such as reset()
, require the device to be open:
const devices = await usb.getDevices();
if (devices.length == 0) {
throw new Error('No devices found');
}
const device = devices[0];
await device.open();
await device.reset(); // Resets the device
It is possible to open a device by ID:
const device = await usb.openDeviceById('0123456789abcdef01234567');
await device.reset();
The device should be closed when it is no longer needed:
await device.close();

Testing
Particle USB has a number of automated test suites and related commands. The most important are:
npm test
- run all testsnpm run test:e2e
- run all end-to-end tests NOTE: Requires additional setupnpm run test:ci
- run all tests excluding device-dependent end-to-end tests as CI doesnpm run lint
- run the linter and print any errors to your terminalnpm run coverage
- report code coverage stats
All tests use mocha, chai, and sinon with coverage handled by nyc.
We recommend running locally if you can as it greatly shortens your feedback loop. However, CI also runs against every PR and error reporting is publicly available.
