Node.js in 2025 is like JavaScript’s glow-up era - faster, smarter, and way more fun to work with. Let’s explore the tools that’ll make your old package.json files blush. 🌶️

Why Node.js Still Runs the Show in 2025

1. Speed That’ll Make Your Head Spin

# Bun vs Node.js cold start comparison
bun start: 0.2s 🚀
node start: 1.8s 🐢

2. TypeScript or Bust

// Deno’s security-first approach
const data = await Deno.readTextFile("secrets.txt"); 
// Throws error unless you add --allow-read

Modern Toolbox for 2025 Devs

1. Bun: The Swiss Army Chainsaw

# Install and create project
curl -fsSL https://bun.sh/install | bash
bun create hyper-app

Why It Slaps:

• Replaces 4 tools (npm, webpack, babel, node)
• Runs TS files like they’re regular JS
• 3x faster API responses

2. Edge Functions: Global Domination

// Vercel Edge Function
export const config = { runtime: 'edge' };

export default (req) => {
  return new Response(`Hello from ${req.geo.city}!`);
};

Real-World Use:
Shopify handles 120K checkout/min using Cloudflare Workers

3. tRPC: REST API’s Midlife Crisis

// Full-stack type safety
// backend/router.ts
export const appRouter = router({
  getUser: publicProcedure
    .input(z.string())
    .query(({ input }) => findUser(input)),
});

// frontend/components.tsx
const { data } = trpc.user.getUser.useQuery('user_123');

AI-Powered Development

// Generate API routes with AI
import { generate } from '@vercel/ai';

const { code } = await generate({
  prompt: "CRUD API for cat memes",
  runtime: 'nodejs'
});

Tools to Try:

• Vercel AI SDK
• LangChain.js (for ChatGPT plugins)
• TensorFlow.js (ML in Node)

export const config = { runtime: 'edge' };

export default (req) => {
  return new Response('Edge > Serverless');
};

3. Lint Like It’s 2025
