Environment Variables

When building web applications usually the same application needs to working in different environments (development, staging, production). There are some variables like API endpoints that are different between these environments.

Mint offers a simple feature for managing these variables. You can create different files .env .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 flab -e or --env which takes the path to the .env file:

mint start --env .env.production
