If slow page loading is a concern for some, I would look into Parcel.js. It is a very minimalist web application bundler. It attempts to avoid all of the configuration involved with other bundlers like Webpack, and makes it very easy to just get your project up and running and bundle the files for production. If you couple that with the "quickbase-cli" tool which allows you to send your bundled files to your Quick Base application via the command line, you're set up with a nice little developer environment that is very easy to configure and use for projects that involved react, ES6, angular etc.
