# React and Env Variables when using Vercel KV

I am using react as the framework, also using Vercel KV to retrieve some values from session storage.

React only allows you to use the env variables as **"REACT_APP_"** prefix. When doing this for **REACT_APP_KV_REST_API_URL and REACT_APP_KV_REST_API_TOKEN,** it returns an error **"Error: @vercel/kv: Missing required environment variables KV_REST_API_URL and KV_REST_API_TOKEN"** I am guessing that it is expecting the value as  KV_REST_API_URL and KV_REST_API_TOKEN, has someone encoutered this issue?

Hey @iaaaaan96! Prefixed environment variables are not provided by default to help protect your database. You should generally avoid exposing database credentials in client-side code. 

I would recommend using `@vercel/kv` in a serverless function. Then you can fetch data from the serverless function in your client-side code.
