Devs using monorepos, when and how do you use them?

Kuala Lumpur, Federal Territory of Kuala Lumpur, Malaysia

Backend + frontend when it can’t be done together in something like Next.js but I’m not likely to use the backend anywhere else. Here’s a recent example https://github.com/gskril/ens-adoption

I like baking /goodbread and building apps on web3 protocols. DevRel @ ENS Labs. gregskril.com

Would you use a monorepo that uses different languages in its packages? Example a python flask project and a nextjs project that uses a common design system built on react.

Less appealing when using diff languages. But could work. Most benefits in my experience have come from easy code sharing between apps in same language using shared locally linked packages.
