How do I create mocked APIs?

What are mocked APIs and why should I use them?

Mocked APIs are simulated APIs that mimic the behavior of real APIs. They are useful for testing and development without relying on live services.

How can I create a mocked API for my project?

You can create a mocked API using tools like Postman, Mockoon, or by writing your own server with frameworks like Express.js.

Can you show me an example of a simple mocked API?

Sure! Here's a simple example using Express.js:

const express = require('express');
const app = express();

app.get('/api/users', (req, res) => {
  res.json([{ id: 1, name: 'John Doe' }, { id: 2, name: 'Jane Doe' }]);
});

app.listen(3000, () => {
  console.log('Mocked API running on http://localhost:3000');
});

This code creates a mocked API endpoint that returns a list of users.

What are some best practices for using mocked APIs?

Some best practices include keeping your mocked data realistic, updating your mocks as your API evolves, and using versioning for your mocked APIs.
