@typed-mongo/express

Express middleware for loading a document by id from route params.

import { createGetByIdMiddleware } from "@typed-mongo/express";

app.get(
  "/users/:id",
  createGetByIdMiddleware({
    param: "id",
    repository: UserRepository,
    attachTo: "user",
  }),
  (req, res) => res.json(req.user),
);

By default, the middleware attaches to both req[attachTo] and res.locals[attachTo], then calls next(). Missing documents are passed to next(error) as TypedMongoNotFoundError; set notFound: "response" to send a 404 JSON response directly.
