Over the years we've debated several times whether to feature monorepos in the Radar. Each time we ended up concluding that the trade-offs introduced by monorepos require a nuanced discussion and the technique is "too complex to blip." Now we're seeing increased interest in monorepos in the JavaScript community, for example, for building applications composed of micro frontends, as discussed in this podcast episode. Whether this is a good idea depends a lot on your situation, and we certainly don't want to give a general recommendation. What we do want to comment on is the tooling. In our teams we see a shift away from Lerna and a strong preference to use Nx for managing JavaScript-based monorepos.
