Environment Variables

Leapkit provides a handy tool to load environment variables from a .env file. This feature is useful when you want to load your environment variables from a file instead of setting them directly in your system, like when you're in development mode.

Creating a .env file #

To use it you can create a .env file in the root of your project and add your environment variables in the following format:

# .env
PORT=8080

Adding Comments #

You can also add comments to your .env file by starting the line with a # character.

# .env
# This is a comment
PORT=8080

Multi-line values #

Leapkit supports multi-line values by using the quoted string syntax:

GITHUB_SECRET_KEY="-----BEGIN RSA PRIVATE KEY-----
MIIEpAIBAAKCAQEAqTmwQppL07nBl/0TEQ5sHcqj/Iz9BmuaaEu26jMXYt1QttHn
-----END RSA PRIVATE KEY-----"

Loading the environment variables #

To load the environment variables from the .env file into your application, perform an underscore import in your main.go file:

// main.go
import _ "github.com/leapkit/core/envload"

This will load the environment variables from the .env file into your application.
