CircleCI JS Client

A JavaScript client for CircleCI's v2 API.

Usage

Setup

First, go and get a CircleCI API Token.

Then all you need to do is import the client class and instantiate it with your token and optionally a project slug and default branch:

import CircleCI from 'circle-client';

const client = new CircleCI('2c818264d2557cd14b9fc3fa538df6ecbc6489f3', {
  // this could also be "github/owner/repo"
  slug: ['github', 'owner', 'repo'],
  // methods that take a branch arg can override this
  branch: 'main',
});

Your project slug consists of:

• The VCS provider (either github or bitbucket)
• The project's owner (e.g. your username or organization name)
• The repo name

Methods

Below is a summary list of available methods. Check out the main client file for fully-typed method signatures.

Paginated results: any method that begins with list returns a Paged<T> object, with an items property containing the API results, and a next_page_token property. If next_page_token is set, you can use it to call the method again with the pageToken argument set to that value to retrieve the next page of results.

Errors

In addition to Fetch errors, the following errors can occur:

• Any method that relies on a project slug will throw a ProjectSlugError if one is not set when the method is called.
• When an API call is made, if the response status code does not equal the success code indicated for that endpoint in API documentation, an APIError will be thrown. The object contains a message (which might be generated by the client or the API), status, and the response object of the Fetch request.
• A method may throw ArgumentError if an invalid set of arguments is provided that cannot be caught by TypeScript.

Development

Development is pretty straightforward:

• Run yarn build to generate a new distribution build.
• yarn lint and yarn format are also available and do exactly what they say.

Testing

Run tests:

• yarn test (optionally with --watchAll)

Run the CircleCI test job locally:

• Download the CircleCI CLI
• If you're changing the config, validate your changes: circleci config validate
• Generate a local config file: circleci config process .circleci/config.yml > .circleci/local.yml
• Execute the test job: circleci local execute -c .circleci/local.yml --job test
