A custom NestJS CRUD generator

const fs = require("fs")

const filePath = path.join(__dirname, "..", "dist", "index.js")
const shebang = "#!/usr/bin/env node\n"

fs.readFile(filePath, { encoding: "utf8" }, (err, data) => {
    if (err) {
        console.error("Error reading the file:", err)
        return
    }
    const updatedContent = shebang + data
    fs.writeFile(filePath, updatedContent, (err) => {

            console.error("Error writing the file:", err)
        } else {
