# namespaced

Allows you to namespace configurations by a key.

The point of namespaces is to structure your code into domains, not isolate them. The reason being is that we more often than not design our namespaces wrong. We have no idea how the final app will look and getting into the issue of "cross domain logic and state" is a pain to refactor all the time due to wrong isolation.

So in Overmind isolation is a discipline, not a technical restriction.

```typescript
import {IConfig } from 'overmind'
import { namespaced } from 'overmind/config'
import * as moduleA from './moduleA'
import * as moduleB from './moduleB'

export const config = namespaced({
  moduleA,
  moduleB
})

declare module 'overmind' {
  interface Config extends IConfig<typeof config> {}
}
```

## 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://overmindjs.org/v24/api-1/namespaced.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.
