Encore vs Express

import { api, RawRequest, RawResponse } from "encore.dev/api";
import express, { request, response } from "express";

Object.setPrototypeOf(request, RawRequest.prototype);
Object.setPrototypeOf(response, RawResponse.prototype);

const app = express();

app.get("/health", (_req, res) => {
  res.send("ok");
});

// Your existing Express routes keep working behind one raw endpoint.
export const expressApp = api.raw(
  { expose: true, method: "*", path: "/!rest" },
  app,
);

import { api } from "encore.dev/api";
import { SQLDatabase } from "encore.dev/storage/sqldb";

const db = new SQLDatabase("users", { migrations: "./migrations" });

interface User {
  id: number;
  email: string;
}

// Moved out of Express: typed request and response, traced automatically.
export const getUser = api(
  { expose: true, method: "GET", path: "/users/:id" },
  async ({ id }: { id: number }): Promise<User> => {
    const user = await db.queryRow<User>`SELECT id, email FROM users WHERE id = ${id}`;
    if (!user) throw new Error("user not found");
    return user;
  },
);
