Description

@cmmv/server is inspired by the popular Express.js framework but has been entirely rewritten in TypeScript with performance improvements in mind. The project integrates common plugins like body-parser, compression, cookie-parser, cors, etag, helmet and serve-static out of the box. Additionally, it plans to support any Express.js-compatible plugin in the near future.

Installation

Install the @cmmv/server package via npm:

$ pnpm add @cmmv/server

Quick Start

Below is a simple example of how to create a new CMMV application:

import cmmv, { json, urlencoded, serverStatic } from '@cmmv/server';
import etag from '@cmmv/etag';
import cors from '@cmmv/cors';
import cookieParser from '@cmmv/cookie-parser';
import compression from '@cmmv/compression';
import helmet from '@cmmv/helmet';

const app = cmmv();
const host = '0.0.0.0';
const port = 3000;

app.use(serverStatic('public'));
app.use(cors());
app.use(etag({ algorithm: 'murmurhash' }));
app.use(cookieParser());
app.use(json({ limit: '50mb' }));
app.use(urlencoded({ limit: '50mb', extended: true }));
app.use(compression({ level: 6 }));
app.use(
    helmet({
        contentSecurityPolicy: {
            useDefaults: false,
            directives: {
                defaultSrc: ["'self'"],
                scriptSrc: ["'self'", 'example.com'],
                objectSrc: ["'none'"],
                upgradeInsecureRequests: [],
            },
        },
    }),
);

app.set('view engine', 'pug');

app.get('/view', async (req, res) => {
    res.render('index', { title: 'Hey', message: 'Hello there!' });
});

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

app.get('/json', async (req, res) => {    
    res.json({ hello: 'world' });
});

app.get('/user/:id', async (req, res) => {
    res.send('User ' + req.params.id);
});

app.get('/users', async (req, res) => {
    res.json(req.query);
});

app.post('/test', async (req, res) => {
    console.log(req.body);
    res.send('ok');
});

app.listen({ host, port })
.then(server => {
    console.log(
        `Listen on http://${server.address().address}:${server.address().port}`,
    );
})
.catch(err => {
    throw Error(err.message);
});
