- Solving common asset loading challenges in a micro frontends context
- Comparing techniques to deal with cacheability and synchronization when loading assets from different teams
- Deciding what bundling strategy is appropriate: many smaller bundles or fewer large ones
- Understanding how on-demand loading can be effectively used with micro frontends
In the preceding chapters, we covered a lot of different integration techniques. But we always focused on the content--integrating markup on the server and in the client. A topic we only discussed in passing is this: How to load the assets associated with a micro frontends? In this chapter, we’ll dive deeper into this significant side topic. There are at least a handful of aspects that you must consider. How can we ensure that teams can deploy a micro frontend and the needed assets on their own? How do you implement cache busting to improve cacheability without introducing tight coupling? How do you ensure that the loaded CSS and JS always fits the server-generated markup? How coarse or fine-grained should your bundles be? Do you want one big bundle for your application, one per team, or even smaller ones? How can on-demand loading techniques help in reducing the upfront asset data the browser needs to process?
