# Function: createClassDecorator()

> **createClassDecorator**\<`TFunction`>(`fn`): `TFunction`

Defined in: [packages/http-framework/src/lib/decorators/utils.ts:32](https://github.com/wolfstar-project/stars-components/blob/5aefd164bc5fc41e5a35d3abf908c288163dd354/packages/http-framework/src/lib/decorators/utils.ts#L32)

Utility to make a class decorator from a function.

## Type Parameters

### TFunction

`TFunction` *extends* (...`args`) => `unknown`

## Parameters

### fn

`TFunction`

The class to decorate.

## Returns

`TFunction`

The decorator.

## Remarks

The decorator is returned with the signature it was given, rather than widened to `ClassDecorator`, so a
decorator built on top of this keeps whatever constraint it declares on its target. This is what lets
[`RegisterCommand`](/documentation/api/http-framework/functions/RegisterCommand) and its siblings reject a target that is not a `Command`.
