I start a new project on glitch.com, and add a variable and value in .env
Plaintext shows:
SECRET=beNice
(no quotes)
console.log(process.env.SECRET)
shows:
process is not defined
How can I call these variables?
Environment variables can only be accessed on the server side of an app, not on the client side as your static site linked there currently is trying to do.
For an example of an app with server side code accessing the environment, you can see in the Glitch node app starter that it's accessing the PORT variable.
