Typescript project references with rollup problems

Rollup Typescript2 example for reproduce problem with typescript project references

Why rollup-typescript2? — because @rollup/plugin-typescript doesn't support typescript project references
Why you need SDK project — in this example, sdk - externalized project. But it also dogfooded from local project frontend
Why you need shared project — because it shared with backend, frontend, and sdk. It shared project with some models and internals. Optimize backend compilation speed and avoid direct sdk usage in backend \

Problem 1 — typings with project references

1. Run npm run -w @project/sdk rollup
2. See build/sdk and build/shared directories

   tree packages/sdk/build/shared
   packages/sdk/build/shared
   └── src
       └── test
           ├── util.d.ts
           └── util.d.ts.map
   
   tree packages/sdk/build/sdk
   packages/sdk/build/sdk
   └── src
       ├── actions
       │   ├── create.d.ts
       │   └── create.d.ts.map
       └── models
           ├── user.d.ts
           └── user.d.ts.map
   
   
   

   It contains types with SRC directory
3. Run npm run -w @project/sdk build and as a result - all typing located in actions and models directories. Additional sdk and shared dirs didn't create
