Overview

Build REST APIs by exposing MongoDB data via Express.

Code Example

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

Web Development Context

In modern web development, understanding MongoDB with Express.js is crucial. By applying this concept correctly, you can build scalable, efficient, and robust applications. Remember that MongoDB is a flexible NoSQL database, meaning that while you have the freedom to design your data as you see fit, following best practices ensures performance and maintainability.

Common Mistakes

• Not using the correct data type (e.g. string instead of ObjectId).
• Forgetting to handle asynchronous operations properly in Node.js.
• Exposing database credentials in frontend code.
