Project: parcel
Task (easy): Setup project with parcel. Here are the requirements:
- Add dev and build to npm scripts.
- Set dev server port to environment variable `process.env.PROJECT_PORT`.
- Generate sourceMap after bundling(If parcel generates sourceMap by default, then you don't need to do anything here).
- Set output directory to `dist` for build command.
- Set output directory to `dist-serve` for dev command.
