Using .env in React + Vite

I was using .env in my react app created using vite. I have a token which needs to be hidden.

As soon as I wrote process.env.AUTH_KEY, I got the following error:

Then on searching I came across the right way of using .env variables in React + Vite project.

**
.jsx

const READ_KEY = import.meta.env.VITE_GH_AUTH_KEY;
const octokit = new Octokit({ auth: READ_KEY });

**

**
.env
VITE_GH_AUTH_KEY = 'your-auth-token'
**
