Hi Manuel,
What about lerna for this ? Is it at another level ?
Also I’m not sure about the space aspect. In the prototype yarn is used, and I only see space in the main node_modules directory. There is nothing in each submodule.
Concerning the speed, I’m much more concerned about the actual build time, then the dependency installation… It would be very interesting to test an alternate build than lerna/yarn on the prototype to check if there is any time won…
The main problem I’ve seen in the prototype is that it always want to rebuild, even though there are no changes to the code. I believe that would be the most important, is to only rebuild a submodule if either it has changed, or a dependency of it has changed.
