Yes, there is, using yarn link. Yarn link allows you to create symlinks to local projects.
Go to the folder libB
and run:
yarn link
Then go to the folder libA
and run:
yarn link libB
NOTE: that libB
must be the name on the package.json
inside the libB
folder
Then you can require your libB
code as usual:
const libB = require('libB')
