shared

The shared package is primarily used for types that you may want to pass between server and client, but it can also be used for functions or libraries. When you create a project with bun create bhvr@latest this is the structure of the package.

shared
├── package.json
├── src
│   ├── index.ts
│   └── types
│       └── index.ts
└── tsconfig.json

It will resemble a barrel export pattern, so the contents of src/index.ts are the following

export * from "./types"

By running either bun run build or bun run dev the types will be compiled and exported from the dist build folder and can be used in client or server.
