Managing Secrets​

Accessing Secrets​

In most Repls, you will be provided with instructions on how to access secrets in your code. Here are some examples of widely-used programming languages:

Python​

import os
print(os.getenv("MY_SECRET"))

JavaScript​

console.log(process.env.MY_SECRET);

Java​

System.out.println(System.getenv("MY_SECRET"))

FAQs​

Why can't I see the Secrets Pane?​

HTML/CSS/JS Repls don't have Secrets since they are statically hosted.

Why aren't my secrets updating?​

Restarting your Repl will reload its secrets, exposing them to your Repl's environment again.

What happens when someone forks my Repl?​

A forked Repl will not contain the secrets/environment variables from the original Repl it was forked from.
