TypeScript type annotation for res.body

Issue

I'm using typescript for my app node.js express. I would like say the res.body is type personne. I have tried this:

router.post('/',(req: Request, res: Response) => {
   const defunt:PersoneModel = res.(<PersoneModel>body);
}

I have this model:

export type PersoneModel = mongoose.Document & {
  nom: String,
  prenom: String,
}

Can you help me?

Thank you.

Solution

We can use as. This should be enough to imply that res.body is PersoneModel

 const defunt = res.body as PersoneModel;

However more straightforward way is declaring type of the variable as a PersoneModel

 const defunt: PersoneModel = res.body;
