Front-end integration via artifact

When teams embrace the concept of micro frontends they have a number of patterns at their disposal to integrate the individual micro frontends into one application. As always there are antipatterns, too. A common one in this case is front-end integration via artifact. For each micro frontend an artifact is built, usually an NPM package, which is pushed into a registry. A later step, sometimes in a different build pipeline, then combines the individual packages into a final package that contains all micro frontends. From a purely technical perspective this integration at build time results in a working application. However, integrating via artifact implies that for each change the full artifact needs to be rebuilt, which is time consuming and will likely have a negative impact on developer experience. Worse, this style of integrating frontends also introduces direct dependencies between the micro frontends at build time and therefore causes considerable coordination overhead.
