Minimize the size of the release version

Question

I was trying to minimize the release version and although managed to reduce the size by building in production mode, the package is still very large. So I'd like to know if there is some general way to reduce the size of the package? Besides, I have the following questions particularly:

1. the root package.json have typescript in devDependency (and somehow yarn won't delete it even in production mode), which accounts for 53MB disk size in node_modules, and I wonder if there's a better way to get rid of it except deleting it manually after the build?
2. some dependencies of dev-packages are very large and I wonder if they are necessary. For example, after deleting webpack-cli from application-manager's dependency, the total size of the node_modules reduced by about 40MB;
3. I don't need electron version of theia, so I deleted dev-packages/electron and examples/electron before the build, but you can tell that there are still some electron-related dependencies remain in node_modules, for example, electron-rebuild, so is there a way to remove electron thoroughly?

My Build Script

yarn --ignore-engines --link-duplicates
yarn --ignore-engines --link-duplicates --production
yarn autoclean --force
rm -fr node_modules/electron/dist
modclean -r
find ./packages -name "*.ts" -exec rm {} \+
find ./dev-packages -name "*.ts" -exec rm {} \+
find ./examples -name "*.ts" -exec rm {} \+
