Step 1: Simply add the property watchFolders to the exports object.
Your metro.config.js file should look something like:
// Absolute path to your package
const packagePath =
'/Users/mac/my-own-packages/my-awesome-package';
module.exports = {
resolver: {
nodeModulesPaths: [packagePath],
// rest of metro resolver options...
},
watchFolders: [packagePath],
// rest of metro options...
};
Step 2:
npm install /Users/mac/my-own-packages/my-awesome-package
