.env.dist.local [upd] -

The .env.dist.local file is a distribution template for local environment configurations. It is committed to your version control system (Git) and contains no real secrets. Instead, it serves as a blueprint showing developers exactly what local variables they can or should customize on their own machines. The Standard Environment Stack vs. The Dist-Local Pattern

Add a step in your Makefile , package.json scripts, or composer.json scripts to automatically copy .env.dist.local to .env.local if the latter does not exist when a developer builds the project.

This file is created by the developer on their machine and is committed to Git.

To understand where .env.dist.local fits, it helps to review the standard hierarchy used by popular configuration loaders like dotenv or framework-specific setups (such as Symfony or Next.js): .env.dist.local

While most developers are familiar with standard .env and .env.local files, advanced workflows often require a specialized file: .

$ envdist development

With .env.dist.local in the repository, onboarding becomes a two-step script: cp .env.dist .env cp .env.dist.local .env.local Use code with caution. The Standard Environment Stack vs

Team-wide defaults for local development (e.g., standard local DB name). .env.local

This ensures that .env.dist.local is tracked, but actual local overrides are NOT.

This comprehensive guide explores the purpose of .env.dist.local , how it fits into your configuration workflow, and best practices for implementing it in your project. Understanding the Environment File Ecosystem

This rule cannot be overemphasized. The .env.local file (and any .local variant) must be included in .gitignore . Committing secrets to version control exposes your application to credential leakage and potential security breaches.

| Practice | Why It's Critical | | :--- | :--- | | | This is the golden rule. Committing a .env file, even a "default" one, risks exposing real secrets. Developers often mistakenly treat .env files as a security layer, but they are not—they are plain text on a filesystem. | | 2. Track .env Only with Safe Defaults | Only the .env file (without .local ) should be committed, and it must only contain safe, non-production defaults. It is a template, not a vault. | | 3. Add All Local Files to .gitignore | Your .gitignore file must explicitly list .env.local , .env.*.local , and any other file that could contain sensitive, machine-specific overrides. | | 4. Do Not Use .env in Production | In a production environment, environment variables should be set directly at the server or container level (e.g., in Kubernetes secrets, AWS ECS, or your PaaS provider's UI). Do not rely on an actual .env file on a production server. | | 5. Consider Modern Secret Management | For highly sensitive secrets, .env files are a risk. Since they are plain text, they are vulnerable to anyone with filesystem access. Modern alternatives include dedicated secret managers like HashiCorp Vault, AWS Secrets Manager, or encrypted dotenv tools like dotenvx . |

# .env.dist.local # This file is committed to git. # Copy this to .env.local and fill in your values. DATABASE_URL=mysql://db_user:db_password@127.0.0.1:3306/db_name API_KEY=your_api_key_here DEBUG=true Use code with caution. 2. Add to .gitignore Ensure the file that will contain real secrets is ignored.

Because .env.local is ignored by Git, developers sometimes forget what keys they have added to it over time. By maintaining a .env.dist.local file in source control, you create a safe checklist of keys without exposing any actual local secrets (like a personal Stripe test key or a local database password).
