Related question: most of the companies I know that have large monorepos have a sizable dedicated team to support their dev tools, and have invested a lot to make monorepos feasible.

Are there any recommendations or standardized tools for structuring monorepos for companies that don't have a dedicated dev tools team? Last I checked, lerna seemed to be the most common tool to support JS monorepos - is that still true? Is there a better tool for a primarily Typescript codebase (primarily React on the front end, Node on the backend, but also native mobile apps)?
