* Create a separate chunk for watch mode via a dynamic import * Bundle chokidar * Handle conditional fsevents import * Only run tests on Node 10 and 12 as we want to do this anyway and chokidar depends on utils.promisify * Improve chunking * Refactor and simplify watcher * Make watcher a proper parameter * Only unwatch and watch on Linux systems * No longer run JS files through TypeScript for improved bundling performance
