# TypeScript

Typing globally available events using TypeScript.

This library is fully using TypeScript and it exports types for everything. So your project can take advantage of the library if you're using TypeScript as well.

### Setup

The setup changes a little bit, add this on top of your application (**your main file**):

```ts
const POST_PICTURE_EVENT = 'picture.post.event'

interface PostPicturePayload {
  image: {
    url: string
    description?: string
  }
  user_id: number
}

declare module 'vue3-emitter' {
  interface Events {
    [POST_PICTURE_EVENT]: PostPicturePayload
  }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.opensoutheners.com/home/vue-3-emitter/typescript.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
