Example ace project.

To install all dependencies, do:

yarn fmt

If using Visual Studio Code, consider installing the prettier extension so you can run the formatter in your editor. The extension should be able to pick up the .prettierrc.js config.

The yarn.lock is checked into source control, managed by yarn and provides deterministic builds. To do so, it captures the dependency graph and the resolved versions based on the state of the yarn registry. It is very important that this file is stable. If it has changes, ensure those changes are related to your current changes and not a remnant of another unrelated branch.

To start the dev server, do:

yarn start

This should open a browser tab to http://localhost:8080.
