This is an example of how to set up a monorepo with Babel 7, Eslint and Jest. It's designed for Node projects, rather than code that runs in the browser. It uses Yarn's native workspaces feature rather than Lerna.
All packages are transpiled from src to lib; lib is ignored by all tools but the only thing that gets published to npm.
Install using Yarn. At the moment, npm doesn't correctly install dependencies since it doesn't have Yarn's workspaces functionality.
Since I prefer using shell scripts over yarn run commands, I've added a shell script that does basic tasks like compiling, linting and testing. Use yarn link to make it available (or you could just run it by pointing to its path directly). The script detects its running directory to ensure it works from anywhere.
If you're copying this example for your own project, you might want to rename the script from task to something more specific.
Please feel free to make an issue if you have questions, or if you know a way to improve this setup.
- Can't seem to run Jest with a
.babelrcfile, rather than ababel.config.jsfile. It doesn't correctly transform dependencies in that case.
- Add command to publish to npm.
