particle-api-js is available from npm to use in Node.js, bower or jsDelivr CDN for use in the browser.


$ npm install particle-api-js


$ bower install particle-api-js

jsDelivr CDN

<script type="text/javascript" src="">


All essential commands are available at the root via npm run <script name> - e.g. npm run lint. To view the available commands, run: npm run

How to run your tests

The Agent integration tests (source) depend on a real HTTP api backend and a valid Particle access token. Be sure to set relevant environment variables to avoid test failures. You can prefix commands test commands like this PARTICLE_API_BASE_URL=<url> PARTICLE_API_TOKEN=<token> npm test

npm test runs the tests.

npm run coverage shows code coverage

npm run test:browser runs tests in a browser via karma.

npm run test:ci runs tests in the exact same way CI system does

How to write scripts that execute against local code changes?

Source code lives in the ./src directory and is built for release via the npm run build command. To create a simple script file to test your changes, follow these steps:

  1. create a js file on your local machine: touch my-api-test.js (somewhere outside of the root of this repo)
  2. within your test js file, init the api client like so:
const ParticleAPI = require('./path/to/particle-api-js'); // Make sure to substitute to correct path
const api = new ParticleAPI();
  1. add in any api calls, etc required to validate you changes
const devices = await api.listDevices({ auth: '<particle-auth-token>' });
console.log('MY DEVICES:', devices);
  1. run it: node ./path/to/my-api-test.js

NOTE: Requiring the root directory works via the main field specified in Particle API JS' package.json file (docs)

How to name npm scripts

npm scripts are the primary means of executing programmatic tasks (e.g. tests, linting, releasing, etc) within the repo. to view available scripts, run npm run.

when creating a new script, be sure it does not already exist and use the following naming convention:


our standard categories include: test, lint, build, clean, docs, package, dependencies, and release. top-level scripts - e.g. npm run clean - will typically run all of its subcategories (e.g. npm run clean:dist && npm run clean:tmp).

npm itself includes special handling for test and start (doc: 1, 2) amongst other lifecycle scripts - use these to expose key testing and start-up commands.

sometimes your new script will be very similar to an existing script. in those cases, try to extend the existing script before adding another one.


  • npm scripts form the developer's API for the repo and all of its packages - key orchestration commands should be exposed here
  • document developer-facing process / tooling instructions in the Development section
  • plan to release your changes upon merging to main - refrain from merging if you cannot so you don't leave unpublished changes to others
  • avoid making changes in files unrelated to the work you are doing so you aren't having to publish trivial updates
  • test files live alongside their source files and are named like *.test.js or *.spec.js
  • if the linter does not flag your code (error or warning), it's formatted properly
  • avoid reformatting unflagged code as it can obscure more meaningful changes and increase the chance of merge conflicts
  • todo comments include your last name and are formatted like: TODO (mirande): <message>

Docs & Resources

First, read the documentation for Particle API JS on the Documentation website. It contains examples to get started.

For more details, read the API reference on GitHub.


There are many snippets of using Particle API JS on the Documentation website and some complete examples in the GitHub examples directory.


Make your changes to the files in the src directory, then from the project directory run:

$ npm run build

The dist directory will contain the compiled and minified files that can be included in your project.

Run tests to make sure your changes are good:

$ npm test

Update the API docs with your changes:

$ npm run docs


See the release process in the file.
