Yarn local packages dependencies

Question

I have the following folder structure:

~ (user home folder)  - api     ...     - package.json  - lib     - libA       ...       package.json     - libB       ...       package.json 

In libA/package.json I have the following local dependency

"dependencies": {     "libB": "../libB",   }, 

So libA depends on libB.

Now I want inside api project to add as local package libA. I execute cd api && yarn add ../lib/libA and I get the following error/Users/a_user/libB doesn't exist. I understand that yarn sees as current director ~/api so when is reading the dependency of libA it sees ../libB and translate it as ~/libB and not as ~/lib/libB

Is there anyway to achieve it without absolute paths ?

Answer 1

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')
