Note: some of these tests no longer run. Be sure to check that CI is green.

Make sure your environment is set up with:

pnpm

In a separate process, run the WebSockets server:

pnpm ws-server

Run the browser tests using Karma:

pnpm test

Run the node.js tests:

pnpm test-node

Run tslint:

pnpm lint

Run format with prettier:

pnpm format

Run all checks (lint/format/browser test/test-node):

pnpm ci

Before Commit

Please make sure you pass all following checks before commit

• pnpm lint (tslint and format)
• pnpm promisetest (promise a+ test)
• pnpm bazel test //packages/zone.js/... (all tests)

Webdriver Test

zone.js also supports running webdriver e2e tests.

1. run locally

pnpm webdriver-start
pnpm webdriver-http
pnpm webdriver-test

Releasing

Releasing zone.js is handled via the release script (run from the root of the repo):

pnpm zonejs:release

Follow the interactive prompts to either create a PR or cut a release.

Releasing is a two step process:

1. Create a PR for release: updates the version in packages/zone.js/package.json, generates the packages/zone.js/CHANGELOG.md with all changes since the last zone.js release, runs a dry-run build, creates and pushes the release branch, and provides a PR link.
2. Cut a release (publish): once the PR is merged, check out the merged release commit, build the package with release config, publish to npm, and tag and push the zone.js-<version> release tag.
