### Shared data globally

`g.shared` is used to share data between post-hooks, pre-hooks, code, and APIs.

- If the user set a shared variable from the one API response.
```ts
g.shared.outPreApi = g.res.output;
```

- User can get that shared variables value in another API.
```ts
g.req.body = g.shared.outPreApi;
```
