express-gny/index.js

A CLI tool that magically set up Node with Express MVC app folder structure

#!/usr/bin/env node

import fs from "fs";
import { execSync } from "child_process";

const projectName = process.argv[2];

if (!projectName) {
  console.log(`
  ❌  Project name is missing!
  
  👉  Please add your project name after the command.

      For example:
      npx express-gny my-app
  `);
  process.exit(1);
}

// Step 1 - Create a folder as : Project Name
fs.mkdirSync(projectName);
process.chdir(projectName);

// Step 2 - npm init and install express
execSync("npm init -y", { stdio: "inherit" });
execSync("npm i express", { stdio: "inherit" });

// Step 3 - create folder structure
fs.mkdirSync("src", { recursive: true });
fs.mkdirSync("src/routes", { recursive: true });
fs.mkdirSync("src/controllers", { recursive: true });
fs.mkdirSync("src/models", { recursive: true });
fs.mkdirSync("src/utils", { recursive: true });
fs.mkdirSync("src/connection", { recursive: true });

fs.writeFileSync(
  "index.js",
  `import express from 'express';
const port = 3000; 
const app = express();
app.use(express.json());
// app.use(router); // <- You'll need to define and import a router

// Example GET route
// app.get('/hello', (req, res) => {
//   res.send('Hello from /hello');
// });

// Example POST route
// app.post('/submit', (req, res) => {
//   res.json({ data: req.body });

app.listen(port, () => {
  console.log(\`Server is running on http://localhost:\${port}\`);
});`
);

console.log("Express Project with MVC Folder Structure created successfully!");
