Hopefully you've had a chance to try the exercises above. Here are my solutions.

Full server code

You will need the db.mjs file from the previous section. You can find it here.

import express from "express";
import cors from "cors";
import db from "./utils/db.mjs";
import { ObjectId } from "mongodb";

const port = process.env.PORT || 5050;
const app = express();
app.use(cors());
app.use(express.json());

app.get("/", (req, res) => {
  const serverStatus = {
    status: "running",
    port: port,
    timestamp: new Date().getTime(),
    message: "Welcome to my book API"
  };
  res.json(serverStatus).status(200);
});

app.get("/books", async (req, res) => {
  const books = await db.collection("books").find({}).toArray();
  res.json(books).status(200);
});

app.get("/books/:id", async (req, res) => {
  const book = await db.collection("books").findOne({ _id: new ObjectId(req.params.id) });
  res.json(book).status(200);
});

app.post("/books", async (req, res) => {
  let book = req.body;
  console.log(book);
  const result = await db.collection("books").insertOne(book);
  res.json(result).status(201);
});

app.put("/books/:id", async (req, res) => {
  let book = req.body;
  const result = await db.collection("books").updateOne({ _id: new ObjectId(req.params.id) }, { $set: book });
  res.json(result).status(200);
});

app.delete("/books/:id", async (req, res) => {
  const result = await db.collection("books").deleteOne({ _id: new ObjectId(req.params.id) });
  res.json(result).status(200);
});

app.listen(port, () => console.log(`Server running on port ${port}`));
