Get started with Jai Server in your project:

npm install jai-server

const JaiServer = require('jai-server');

const app = JaiServer();

app.get('/', (req, res) => {
  res.send('Welcome to Jai Server!');
});

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

const JaiServer = require('jai-server');

const app = JaiServer({
  static: {
    dir: `${__dirname}/public`,
    basePath: '/static',
  },
});

app.listen({ port: 3000 }, () => {
  console.log('Static files served at http://localhost:3000/static');
});

const fs = require('fs');
const JaiServer = require('jai-server');

const app = JaiServer({
  http2: true,
  allowHTTP1: true,
  https: {
    key: fs.readFileSync('path/to/key.pem'),
    cert: fs.readFileSync('path/to/cert.pem'),
  },
});

app.get('/', (req, res) => {
  res.send('Secure Jai Server!');
});

app.listen({ port: 443 }, () => {
  console.log('Secure server running on https://localhost');
});

const JaiServer = require('jai-server');

const app = JaiServer();

app.get('/users/:id', (req, res) => {
  res.json({ userId: req.params.id, message: 'User details' });
});

app.listen({ port: 3000 });

const JaiServer = require('jai-server');

const app = JaiServer();
const router = JaiServer.Router();

// Middleware
app.use((req, res, next) => {
  console.log(`Request received at ${new Date()}`);
  next();
});

// Router
router.get('/hello', (req, res) => {
  res.send('Hello from the router!');
});

app.use('/api', router);

app.listen({ port: 3000 });

Sends a response in HTML, text, or any other format. Automatically sets the appropriate Content-Type header.

app.get('/hello', (req, res) => {
  res.send('Hello, World!');
});

Sends a JSON response with Content-Type: application/json.

app.get('/user', (req, res) => {
  res.json({ id: 1, name: 'John Doe' });
});

Redirects the client to the given URL. The default status code is 302.

app.get('/old-route', (req, res) => {
  res.redirect('/new-route');
});

Sets the HTTP status code for the response. Chainable with other response methods.

app.get('/error', (req, res) => {
  res.status(404).send('Page Not Found');
});

Sets custom headers for the response.

app.get('/custom-header', (req, res) => {
  res.header('X-Custom-Header', 'MyValue').send('Header set!');
});

Serves a file to the client. Options can include root directory, cache settings, etc.

app.get('/download', (req, res) => {
  res.sendFile('path/to/file.txt',{
    fallthrough:false // Optional: default false
  },(err)=>{ // Optional Call Back/Next

  });
});

Jai Server supports middleware and routers for more complex applications:

const JaiServer = require('jai-server');
const app = JaiServer();
const router = JaiServer.Router();

// Middleware
app.use((req, res, next) => {
  console.log('Time:', Date.now());
  next();
});

// Router
router.get('/hello', (req, res) => {
  res.send('Hello from the router!');
});

app.use('/api', router);

app.listen({ port: 3000 });

Creates a new Jai Server instance.

Routes an HTTP request, where METHOD is the HTTP method in lowercase.

app.get('/path', (req, res) => { /* ... */ });
app.post('/path', (req, res) => { /* ... */ });
// Other HTTP methods: put, patch, delete, options, head

Mounts middleware function(s) at the specified path.

Starts the server.

• Middleware Chaining: Create complex request processing pipelines
• Custom Error Handling: Implement application-specific error management
• Request Body Parsing: Built-in support for JSON and URL-encoded bodies
• Modular Routing: Organize routes using the Router class
• WebSocket Support: Real-time, bidirectional communication
• Database Integration: Easy connection with popular databases
• Authentication Middleware: Secure your routes and APIs
