How to Use Environment Variables in Replit

‍

This tutorial shows how to access the secret values you've stored in Replit's Secrets tab inside your project's code.

Note: You need a Replit account and an existing project with at least one secret already set. If you haven't added one yet, see How to Set Environment Variables in Replit first.

1. Sign in at replit.com and open your project from the dashboard.
2. In your workspace, click New Tab and search for Secrets in the left sidebar (the lock icon).
3. In the Secrets tab in the left sidebar, confirm your variable is saved - for example, [Name]_TOKEN.
4. Open your project file in the editor. The file name depends on your project type:
   
   • Python: main.py(default) or (project name)_main.py(custom) 
   • Node.js: index.js(default) or (project name)_index.js(custom)
5. In your code, call the environment variable by its key name. 
   
   • In Python, use os.environ.get('TOKEN'). 
   • In Node.js, use process.env.TOKEN.
6. Run your project to confirm it reads the value correctly - for example, your Telegram or Discord bot should connect and come online using the stored token.
