Glossary

Terminology commonly used in React Native Packager / Metro Bundler is explained here. This document is work in progress, please help completing it.

Build Root

Configuration files (rn-cli.config.js) support configuring one or more roots that are watched for file changes during development. In the context of the integration with the js_* rule family in Buck, there is only a single root, the build root used by Buck.

Local Path

A local path / localPath is the path to a file relative to a build root.
