Belajar Express JS | 26. Setup Router User Menggunakan Router Group API Pattern

Express JS is a popular web application framework for Node.js. In this article, we will learn how to set up a router user using the Router Group API pattern in Express JS.

The Router Group API pattern is a design pattern that allows you to group related routes and middleware together in a more organized and modular way. This can make your code easier to read, maintain, and scale.

How to Set Up a Router User Using Router Group API Pattern

First, make sure you have Express JS installed in your project. You can install it using npm by running the following command in your terminal:


npm install express


Next, create a new file for your router user. In this example, we will create a file called userRouter.js.

Inside userRouter.js, we will define our user routes using the Router Group API pattern. Here is an example code snippet:


const express = require('express');

const userRouter = express.Router();

userRouter.get('/', (req, res) => {
res.send('Get all users');
});

userRouter.post('/', (req, res) => {
res.send('Create a new user');
});

userRouter.put('/:id', (req, res) => {
res.send('Update user with id ' + req.params.id);
});

userRouter.delete('/:id', (req, res) => {
res.send('Delete user with id ' + req.params.id);
});

module.exports = userRouter;


Finally, in your main Express JS file (usually app.js), you can import and use the user router like this:


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

const userRouter = require('./userRouter');

// Use the user router for all requests that start with '/users'
app.use('/users', userRouter);

// Start the Express server
app.listen(3000, () => {
console.log('Server running on port 3000');
});


That’s it! You have now successfully set up a router user using the Router Group API pattern in Express JS. This will allow you to easily manage and organize your user-related routes in a more structured way.

Happy coding!
