lerna VS ultra-runner

On Netlify's enterprise tier, approximately 46% of builds are monorepos, with the majority leveraging Nx and Lerna. Recognizing this trend, Netlify has focused on enhancing the setup and deployment experiences for monorepo projects. In particular they worked on an "automatic monorepo detection" feature. When you connect your project to GitHub, Netlify automatically detects if it's part of a monorepo, reads the relevant settings, and pre-configures your project. This eliminates the need for manual setup. This feature also extends to local development via the Netlify CLI.

This is the exact problem monorepos were born to solve. Not only will a monorepo let you share UI components, you'll be able to gradually add shared application logic as well (for instance, do all of your apps have their own logic for connecting to a database? you could roll that into a shared library with a monorepo). There are a lot of tools for accomplishing this in JS, but probably the most popular is lerna, which is built on top of NX (though lots of teams roll their own monorepo in nx without lerna, which IMO is a totally valid option).

To begin, you need to prepare your environment. A few ways to build a React package include tools like Bit, Storybook, Lerna, and TSDX. However, for this tutorial, you will use a zero-configuration bundler for tiny modules called Microbundle.

If so, are you using a monorepo tool like Nx or Lerna? If not, start there and see if it solves your problem.

I mean I don't know what your monorepo looks like, but for example infernojs (actually written with typescript) uses lerna, and lerna seems simpler than typescript references

Tools for publishing, such as Lerna (when using the --conventional-commit flag), follow this convention when incrementing package versions and generating changelog files.

We could improve part of this by using something like Lerna. With the right configuration, Lerna can be really helpful.

It feels dirty to be adding express as a dependency to a react project, but I'm pretty sure TRPC requires all of client and server code to be in the same node.js project, since types are shared. I've read that you can use a tool like Lerna to share types between node projects, but it requires a build step, which would diminish the benefits of TRPC.

Cache built files to avoid rebuilds. For example nx.js, yarn-plugin-change, ultra-runner

Then comes the question of triggering docker builds if you need to release images. If you have many apps, it's better to create a docker file for each, so you can decide which one needs to be built. Nx help in this area, because it can compute which apps needs to be rebuilt... If you have only few apps you can use github action paths (ie: simplified example) or eventually make use of things like [ultra-runner](https://github.com/folke/ultra-runner). Anyway docker and nextjs take times to setup (env...). It's another story.

ultra-runner: scripts for JavaScripts monorepo management. Plugs in with Yarn, pnpm, and Lerna. Supports parallel building.
