Make your localhost app live on the internet using ngrok.

To make your local Node.js app live on the internet using ngrok, follow these steps:

✅ Prerequisites:

• Your Node.js app should already be running (e.g., on port 3000 or any other port).
• ngrok installed on your machine.

---

🔧 Step-by-Step Guide:

1. Install ngrok (if not already installed):

npm install -g ngrok

Or download from: https://ngrok.com/download

---

2. Start your Node.js app locally

For example:

node app.js

Let’s assume it runs on http://localhost:3000

---

3. Sign up for a free ngrok account:

Go to: 👉 https://dashboard.ngrok.com/signup

---

4. Verify your email (if prompted)

---

5. Get your authtoken:

After login, go to: 👉 https://dashboard.ngrok.com/get-started/your-authtoken

You’ll see something like:

ngrok config add-authtoken 2S6abc123XYZ....

---

6. Copy and run the command in your terminal:

ngrok config add-authtoken YOUR_AUTHTOKEN_HERE

Replace YOUR_AUTHTOKEN_HERE with your actual token

---

7. Now start ngrok again:

ngrok http 3000

You should now see:

Forwarding                    https://abcd1234.ngrok.io -> http://localhost:3000
