expo-router-auth-guard/bin/expo-router-auth-guard.js

A minimal yet powerful starter to quickly launch a mobile app using Expo and Supabase, including:

#!/usr/bin/env node

import { execSync } from "child_process";
import fs from "fs-extra";
import path from "path";
import { fileURLToPath } from "url";

const __dirname = path.dirname(fileURLToPath(import.meta.url));

// Nom du dossier cible
const appName = process.argv[2];

if (!appName) {
    console.error("❌ Please specify a project name :");
    console.log("   npm create expo-auth-guard@latest my-app");
    process.exit(1);
}

const isCurrentDir = appName === "." || appName === "./";
const targetDir = isCurrentDir
    ? process.cwd()
    : path.resolve(process.cwd(), appName);

if (!isCurrentDir && fs.existsSync(targetDir)) {
    console.error(
        `❌ Folder "${appName}" already exists. Please choose another name.`
    );
    process.exit(1);
}

if (isCurrentDir && fs.readdirSync(targetDir).length > 0) {
    console.warn(
        "⚠️ Current directory is not empty. Files may be overwritten."
    );
}
const templateDir = path.resolve(__dirname, "../template");

if (fs.existsSync(targetDir)) {
    console.error(
        `❌ Folder "${appName}" already exists. Please choose another name.`
    );
    process.exit(1);
}

try {
    console.log(`🚀 Creation of the project ${appName}...`);
    fs.copySync(templateDir, targetDir);

    process.chdir(targetDir);

    // Initialisation Git + npm install (optionnel)
    execSync("git init", { stdio: "inherit" });
    execSync("npm install", { stdio: "inherit" });

    console.log("✅ Project created successfully !");
    console.log(`👉 cd ${appName}`);
    console.log("   npm run start");
} catch (err) {
    console.error("❌ Error creating project :", err);
}
