simples

0.8.8

simpleS is a simple web framework for Node.JS designed to create HTTP(S) servers and clients with some special features:

• High performance and simple structure with minimum configuration
• Advanced routing for http requests, static files and errors
• Unique interface for requests and responses (named as connection)
• Response compression (deflate and gzip, disabled by default)
• Virtual Hosting
• CORS support
• Sessions (disabled by default)
• Template engine support
• WebSocket implementation (version 13, RFC 6455)
• Client API for HTTP requests and WebSocket connections
• Browser simple API for AJAX and WebSocket

Works with node.js 0.10+ and io.js 1.0+ !

Any feedback is welcome!

• recache
• simpleR

Instalation

npm install simples

Examples

See the folder examples/ in the module directory, it contains examples that cover most simpleS features.

Usage

Server Creation

var simples = require('simples');

var server = simples(); // Your server is set up on port 80

// Enable compression (default is deflate)
server.config({
    compression: {
        enabled: true
    }
});

// Serve static files located in the folder "static"
server.serve('static');

// Catch 404 Error
server.error(404, function (connection) {
    connection.end('Error 404 caught');
});

// Create the first route
server.get('/', function (connection) {
    connection.end('Simples Works');
});

Client Creation

var simples = require('simples');

var client = simples.client();

// GET request
client.get('/').on('body', function (response, body) {
    console.log('Response status: ' + response.status);
    console.log('Response body: ' + body.toString());
});

// POST request
client.post('/send').send(/* data */).on('response', function (response) {
    // Do something with the response
}).on('body', function (response, body) {
    console.log('Response body: ' + body.toString());
});

Virtual Hosting

var host0 = server; // The server is in the same time the main host
var host1 = server.host('example.com'); // Other hosts
var host2 = server.host('example2.com');

// Now for each host you can apply individual routing
host0.get('/', function (connection) {
    connection.end('Main Host');
});

host1.get('/', function (connection) {
    connection.end('Host 1');
});

host2.get('/', function (connection) {
    connection.end('Host 2');
});

WebSocket

Let's create an echo WebSocket server:

server.ws('/', {
    limit: 1024, // The maximum size of a message
    mode: 'text', // Set connection mode, see docs for more info
    origins: ['null'] // Set accepted origins, "null" for localhost
}, function (connection) {

    // Log the new connection
    console.log('New connection');

    // Listen for messages to send them back
    connection.on('message', function (message) {
        console.log('Message: ' + message.data);
        connection.send(message.data);
    });

    // Log connection close
    connection.on('close', function () {
        console.log('Connection closed');
    });
});

Access the server from the browser built-in WebSocket API:

var socket = new WebSocket('ws://localhost/', 'echo');

// Listen for messages
socket.onmessage = function (event) {
    console.log(event.data);
};

// Send the first message
socket.send('ECHO');

Access the server from the browser simpleS WebSocket API:

var socket = simples.ws('/', ['echo']);

// Listen for messages
socket.on('message', function (message) {
    console.log(message.data);
});

// Send the first message
socket.send('ECHO');

Access the server from server-side simpleS client WebSocket API:

var simples = require('simples');

var client = simples.client();

var socket = client.ws('/');

// Listen for messages
socket.on('message', function (message) {
    console.log(message.data);
});

// Send the first message
socket.send('ECHO');
