.env.go.local May 2026

VS Code and GoLand may not automatically respect build tags. Configure your settings.json:

    "go.buildTags": "local"

# Local development overrides
.env.go.local

Want explicit control? Write a small merge function:

func loadConfig() 
    defaults, _ := godotenv.Read(".env")
    overrides, _ := godotenv.Read(".env.go.local")
for k, v := range overrides 
    defaults[k] = v
for k, v := range defaults 
    os.Setenv(k, v)

This gives you predictable override behavior: local wins, always.

Creating a .env.go.local file is a common practice for Go developers, especially when working on projects that require environment-specific configurations. This file typically contains local environment variables that are not committed to version control, keeping sensitive information like API keys, database credentials, and other secrets secure.

Below is a useful content example for a .env.go.local file for a Go application. This example assumes your Go application interacts with a database, uses an external API, and requires a specific log level for local development: .env.go.local

# Database configuration
DB_HOST=localhost
DB_PORT=5432
DB_USER=myuser
DB_PASSWORD=mypassword
DB_NAME=mydb
# API Keys
EXTERNAL_API_KEY=your_external_api_key_here
EXTERNAL_API_SECRET=your_external_api_secret_here
# Logging
LOG_LEVEL=DEBUG
# Other local settings
RUN_MODE=local

In a real-world scenario, you would replace placeholders like myuser, mypassword, your_external_api_key_here, and your_external_api_secret_here with your actual credentials or keys.

Go developers value clarity and minimal magic. The .env.go.local pattern is:

Never commit .env.go.local to GitHub, GitLab, or any version control system. VS Code and GoLand may not automatically respect build tags

Open your .gitignore file and add the filename:

# .gitignore
Organize your project to separate shared configuration from local overrides:
/myapp
├── go.mod
├── main.go
├── config/
│   ├── config.go          // Shared logic and defaults
│   └── env.go.local       // Local overrides (ignored by git)
└── .gitignore

Here’s the pattern that fits Go’s simplicity: # Local development overrides

Why go.local? It’s explicit, avoids collisions with other projects (Node, Python, etc.), and signals that this override file belongs to this Go service.
