Adding Code-Splitting Capabilities To A WordPress Website Through PoP

Speed is among the top priorities for any website nowadays. One way to make a website load faster is by code-splitting: splitting an application into chunks that can be loaded on demand — loading only the required JavaScript that is needed and nothing else. Websites based on JavaScript frameworks can immediately implement code-splitting through Webpack, the popular JavaScript bundler. For WordPress websites, though, it is not so easy. First, Webpack was not intentionally built to work with WordPress, so setting it up will require quite some workaround; secondly, no tools seem to be available that provide native on-demand asset-loading capabilities for WordPress.
