Before running the project, make sure you have:

• Node.js
• npm

Check your installed versions:

How to Run the App

You need two terminal windows.

---

Terminal 1 — Start the Numberline Server

From the project root:

cd numberline
node server.js

Keep this terminal running.

---

Terminal 2 — Start the Frontend

Open a second terminal and go to the project root:

cd number-spectra
npm run dev

After the frontend starts, open the local URL shown in the terminal.

It is usually something like:

http://localhost:5173

The exact port may be different depending on your setup.
