better param parsing:

interface Params {
  postId: string;
}

interface Body {
  title: string;
  content: string;
}

interface Query {
  draft?: 'true' | 'false';
}

app.post(
  '/posts/:postId',
  (req: Request<Params, any, Body, Query>, res: Response) => {
    const { postId } = req.params;
    const { title, content } = req.body;
    const { draft } = req.query;

    res.json({ postId, title, content, draft });
  }
);
