# nestjs-create-param-decorator-with-injections

A library providing service injections through an object that will be used in

the `createParamDecorator` like function.

# Example

```ts

import { createParamDecoratorWithInjections } from 'nestjs-create-param-decorator-with-injections'

const UserSettings = createParamDecoratorWithInjections(async (_data, _ctx, { user, db }) => {

  const settings = await db.settings.where({ owner: user })

  return settings

}, { user: UserService, db: DatabaseService }) // Services to inject

@Injectable()

class AppService {

  getUserTheme(@UserSettings() settings: UserSettings) {

    return settings

  }

}

```

The `createParamDecoratorWithInjections` function is very similar to

`createParamDecorator` but the function it takes also have the two more

arguments where the third argument is providing the services that are injected

and the fourth one contains extra data such as the initial data passed to the

decorator.
