Basic Express.js Setup

import express from 'express';

const app = express();
const port = ${1:3000};

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

app.listen(port, () => {
    console.log(`Server running on port ${port}`);
});

HTTP Methods

!eget: Defines a GET route.

app.get('${1:/path}', (req, res) => {
    ${2:res.send('GET request to the homepage');}
});

!epost: Defines a POST route.

app.post('${1:/path}', (req, res) => {
    ${2:res.send('POST request to the homepage');}
});

!eput: Defines a PUT route.

app.put('${1:/path}', (req, res) => {
    ${2:res.send('PUT request to the homepage');}
});

!edelete: Defines a DELETE route.

app.delete('${1:/path}', (req, res) => {
    ${2:res.send('DELETE request to the homepage');}
});

!epatch: Defines a PATCH route.

app.patch('${1:/path}', (req, res) => {
    ${2:res.send('PATCH request to the homepage');}
});

!eoptions: Defines an OPTIONS route.

app.options('${1:/path}', (req, res) => {
    ${2:res.send('OPTIONS request to the homepage');}
});

!ehead: Defines a HEAD route.

app.head('${1:/path}', (req, res) => {
    ${2:res.send('HEAD request to the homepage');}
});

Middleware and Route Use

!emiddleware: Adds a middleware for logging request methods.

app.use((req, res, next) => {
  console.log("${1:Request Type}:", req.method);
  next();
});

!eruse: Declares a middleware route.
```
app.use("${1:/}", "${2:}");
```

Express Router

!routeget1: Creates a router with a GET route.

});

export default router;

    ${2:res.send('POST request');}
});

export default router;

!routeput1: Creates a router with a PUT route.

import { Router } from 'express';

const router = Router();

router.route('${1:/path}').put((req, res) => {
    ${2:res.send('PUT request');}

    ${2:res.send('DELETE request');}
});

export default router;

Express.js Middleware and Full Setup

app.use((req, res, next) => {
  console.log("${1:Request Type}:", req.method);
  next();
});

!esetup: Basic Express.js setup with JSON and URL-encoded body parsers.

import express from 'express';

const app = express();
const port = ${1:3000};

app.use(express.json());
app.use(express.urlencoded({ extended: true }));

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

app.listen(port, () => {
    console.log(`Server running on port ${port}`);
});

!efullsetup: Full Express.js setup with additional middleware.

import express from 'express';
import cookieparser from 'cookie-parser';
import cors from 'cors';

const app = express();
app.use(cookieparser());
app.use(
  cors({
    origin: process.env.CORS_ORIGIN,
    credentials: true,
  })
);
const port = ${1:process.env.PORT || 3000};

app.use(express.json());
app.use(express.urlencoded({ extended: true }));

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

app.listen(process.env.PORT, () => {
    console.log(`Server running on port ${process.env.PORT}`);
});
