To truly understand its utility, we must look at how it fits into a typical configuration hierarchy. The Priority Hierarchy
(Environment-specific defaults, e.g., .env.development ) .env.default.local
To ensure your team knows that a .env.default.local file is supported or required for specific workflows, maintain a .env.example file in your repository. This file serves as a template, showing the keys without the sensitive values: To truly understand its utility, we must look
To prevent accidental leaks, ensure that your .gitignore file explicitly targets all variations of local environment files. Add the following block to your project root: Add the following block to your project root:
The existence of .env.default.local should be documented in the project's README. New developers need to know that if they need to diverge from the standard development setup, they should create this file rather than editing the committed defaults.
If your team requires special mock services (e.g., local mock servers) that are different from production and different from the standard shared .env settings, .env.default.local can provide these defaults for everyone without changing the shared configuration. 3. Separation of Concerns
