I'm trying to setup a monorepo with 3 services sharing some library code.

This is the current situation:

repo: web
pdf/
  package.json
    reference to shared-ts using github url
  tsconfig.json
frontend/
  package.json
    reference to shared-ts using github url
  tsconfig.json

repo: mobile (react-native)
  package.json
    reference to shared-ts using github url
  tsconfig.json

repo: shared-ts
  package.json
  tsconfig.json

This works but it's a pain to commit to shared-ts, build, change the hash in package.json and commit again.

This is what I'd like to achieve:

repo: monorepo
pdf/
  package.json
    reference to ../shared-ts
  tsconfig.json
frontend/
  package.json
    reference to ../shared-ts
  tsconfig.json
mobile/
  package.json
    reference to ../shared-ts
  tsconfig.json
shared-ts/
  package.json
  tsconfig.json

So far I've tried:

• TypeScript project references, but it seems like there is no way to have dependencies in the shared-ts project
• "shared-ts": "../shared-ts" in package.json but it copies shared-ts into the node_modules of each package so I have to re-run yarn everytime I make a change
• yarn link in postinstall: error TS2307: Cannot find module 'shared-ts' or its corresponding type declarations.
• creating a symlink directly in postinstall with ln -s ../shared-ts/ node_modules/shared-ts/ but it seems TypeScript fails to find the module
• npm link in postinstall seems like the most promising but it's really slow and I'm having trouble running it in CI because of some permissions issues.

Is there a good way of doing this? Any ideas on other things I could try?

using yarn workspace & learn

here is an example monorepo-template

I have done the things you are curious about in a recent project. Desired results can be achieved by monorepo using learna and yarn workspace. For details, please go to this link

With the above, we will be creating a package of types. In other packages, we will be just importing types from packages like below:

import { Post } from "@types";

Things are much easier this way than linking packages ourslef.
