Avoiding build-time compilation to assemble Microfrontends
There is a current trend in the frontend community to move as many tasks as possible to the build time phase of application compilation, rather than the runtime. Good examples of these are static site generation, where the HTML pages are generated at build time, or Ahead of Time (AoT) compilation in Angular, which improves the overall performance of an application.
While, in general, build-time compilation is a good practice, reducing the load on the browser and JavaScript engines during the runtime phase, it doesn’t help when assembling the microfrontend. This is because every time any microfrontend changes, you need to rebuild the assembly layer as well, defeating the principle of independent micro app deployments.
We can choose to have individual micro apps do more work during build time (e.g., generate static pages), but the assembling of micro apps or module federation should always be done on the server or...
