Environment Variables

When building web applications usually the same application needs to work in different environments (development, staging, production). There are some variables like API endpoints that differ depending on the environment.

Mint offers a simple feature for managing these variables. You can create different files .env and .env.production which have contents like this:

ENDPOINT=http://localhost:3001
WSENDPOINT=ws://localhost:3001

Then in Mint code you can inline them:

component Main {
  fun render : Html {
    <div>
      <{ @ENDPOINT }>
    </div>
  }
}

Specifying .env file

The Mint CLI has a global flag -e or --env which takes the path to the .env file:

mint start --env .env.production
