Edge-Side Composition

In the previous chapter, you saw the complexity and potential gains that are involved when using server-side composition. As already mentioned in Chapter 7, a slightly simpler variant of server-side composition is the edge-side composition pattern. Besides being a less complex solution, this pattern aims to bring bigger performance improvements compared to server-side composition.

While edge-side composition usually lives on edge servers such as a CDN, the enhancements of this pattern can be applied on-premises, too. In the end, the ideas behind this simplification are what matter here. If the implementation is simple enough to be deployed on a CDN, then we know it fits this pattern.

One of the most important things we’ll do in this chapter is simplify the example from the previous chapter. For this reason alone, it makes sense to have a closer look at edge-side composition. Again, for didactic purposes, we will not use a full-fledged micro frontend...
