See package.json in already existing packages and create new with-foo/package.json.
Put source code in with-foo/src/, it will be transpiled and bundled into with-foo/dist/, with-foo/lib/ and with-foo/es/.
Put tests written with Jest in with-foo/test/.
Put demo in with-foo/demo/, it will be rendered and wrapped with HMR.
