Use .env File as a Local Substitute for Parameter Store

This is the simplest and most common approach for local development:

Idea:

• If running locally, load config from .env

• If running in production/staging, fetch from AWS Parameter Store

Example

import (
	"os"
)

// Load parameter based on environment
func getParameter(name string) string {
	if os.Getenv("ENV") == "local" {
		// Load from .env or environment variable
		return os.Getenv(name)
	}
	// In non-local environments, load from AWS SSM
	val, err := getFromSSM(name) // implement this function
	if err != nil {
		panic(err)
	}
	return val
}

Your .env file would look like:

ENV=local
CLIENT_ID_BURTON=abc123
CLIENT_SECRET_BURTON=xyz456

Use github.com/joho/godotenv to load it

godotenv.Load()
