I’ve had limited success with GitHub - casey/just: 🤖 Just a command runner · GitHub in polyglot repos but have in mind it’s more of a generic task runner without some truly dedicated DAG dependency management like other modern tools have.

I want to try GitHub - ejholmes/walk: A fast, general purpose, graph based build and task execution utility. · GitHub but haven’t had a chance yet. I’ve heard good feedback in HN.

While I haven’t used it on a big monorepo yet, I really enjoyed using earthly.dev in a phoenix project with a non-trivial webpack setup.

It’s basically Dockerfile meets Makefile, which is surprisingly powerful since you can use docker images as the base for your targets, so you don’t have to think about how to setup your build environment.

What you normally do is have multiple runners per project. Most of my projects kick off different pipelines in api/, mobile/ or client/ (depending on if there were changes ofc).

I use this pattern on Circle, azure devops and github actions.

Edit: assuming you deploy the various platforms to different places. If your client is served by elixir you would just have another step to compile assets on top of the rest.

While makefiles etc are fine, 99.99% of the time Bash will do just fine.
