monorepo.dep-lint
Within a monorepo you have many packages and those packages can tend to use the same dependencies and devDependencies. The issue is when packages/a and packages/b use different versions of a shared dependency for instance one uses ^4.5.0 and the other ^4.5.2 this spit is often unnecessay. This tool is used to check for these type of inconsistancies and provide a list of issues to fix. Another very important feature of this tool is the ability to check if all the devDependencies in your packages are included in the root package.json.
