Introduction to Adhoc-Router

The adhoc-router is a dynamic routing library in JavaScript, designed to handle dynamic route integrations effectively. It is known for its flexibility and ease of use, providing dozens of powerful APIs for developers to leverage.

Key APIs of Adhoc-Router

Here we will walk through some of the most useful APIs with code snippets to help you understand their usage:

1. Creating a Router

Create an instance of the router:

  const Router = require('adhoc-router');
  const appRouter = new Router();

2. Defining Routes

Define routes using the get, post, put, and delete methods:

  appRouter.get('/home', (req, res) => {
    res.end('Welcome to the Home page');
  });

  appRouter.post('/login', (req, res) => {
    // Handle login post data
    res.end('Login Successful');
  });

  appRouter.put('/user/:id', (req, res) => {
    // Update user with given id
    res.end(`User ${req.params.id} updated`);
  });

  appRouter.delete('/user/:id', (req, res) => {
    // Delete user with given id
    res.end(`User ${req.params.id} deleted`);
  });

3. Middleware Integration

Use middleware to process requests:

  appRouter.use((req, res, next) => {
    console.log('Request URL:', req.url);
    next();
  });

4. Dynamic Route Matching

Support for dynamic and nested routing:

  appRouter.get('/user/:id/profile', (req, res) => {
    res.end(`Profile of user ${req.params.id}`);
  });

5. Error Handling

Define a centralized error handling middleware:

  appRouter.use((err, req, res, next) => {
    console.error(err.stack);
    res.status(500).send('Something broke!');
  });

Example App Using Adhoc-Router

Below is an example of how these APIs can be combined to create a simple web application:

  const http = require('http');
  const Router = require('adhoc-router');

  const appRouter = new Router();

  // Define routes
  appRouter.get('/', (req, res) => {
    res.end('Welcome to the Homepage');
  });

  appRouter.get('/about', (req, res) => {
    res.end('About Us');
  });

  appRouter.post('/contact', (req, res) => {
    res.end('Contact Form Submitted');
  });

  // Error handling middleware
  appRouter.use((err, req, res, next) => {
    console.error(err.stack);
    res.status(500).send('Internal Server Error');
  });

  // Create server and use the router for requests
  const server = http.createServer((req, res) => {
    appRouter.handle(req, res);
  });

  server.listen(3000, () => {
    console.log('Server is running on port 3000');
  });

With this comprehensive guide, you are now ready to implement adhoc-router in your projects to build efficient and dynamic web applications.
