The primary benefit is that it enforces a "Vault-First" mindset. You aren't manually editing a .env file and hoping you don't accidentally commit it. You are pulling from a secure source, and the .env.vault.local file is a generated artifact.
Ensure it is explicitly in your .gitignore :
npx dotenv-vault local build
Keep your .env.vault file in your repository, but strictly .gitignore your local .env files and your DOTENV_KEY . The decryption key should only be injected on your server's environment variables dashboard (e.g., Render, Vercel, AWS).
The dotenv-vault local build command offers a simple, elegant, and robust solution to the modern challenge of secret management. By generating the local and .env.vault files, it bridges the gap between frictionless local development and secure production deployments. .env.vault.local
You no longer need to scatter your production secrets across multiple cloud providers, messaging apps, or third-party tools.
The real power of the vault is in how it's loaded by your application at runtime. The primary benefit is that it enforces a
Remove the file from the repository ( git rm --cached .env.vault.local ). Add it to .gitignore . Have each team member regenerate their own local file. Conclusion
对于安全要求较高的项目，定期轮换加密密钥是最佳实践。dotenv-vault 支持密钥轮换： Ensure it is explicitly in your
