Developer environment notes

This page explains the project’s local .env behavior and how to handle environment files and secrets when developing OmniRoute.

.env postinstall behavior

The project may generate a local .env file during npm install / postinstall for developer convenience. This file is intended only for local development and testing and must never be committed to version control.

Key points:

• The repository’s .gitignore already ignores .env* files (see the .gitignore entry). Do not remove or alter that rule unless you deliberately intend to commit a specific example file and have a documented process for it.
• If a real secret is accidentally committed to the repo, rotate/revoke the credential immediately and remove it from the repository history (for example, using git filter-repo or an equivalent remediation workflow). Contact the security/contact owner if you need help.
• For CI and production, use the CI secrets or a secrets manager (GitHub Actions Secrets, Azure Key Vault, HashiCorp Vault, etc.) rather than committing secrets to files.

Recommended local workflow

• Keep .env in your local workspace only. Use .env.example (already tracked) to document required variables and acceptable example values.
• When running tests locally that require secret-like values, prefer synthetic placeholders or runtime-generated ephemeral keys rather than real credentials.
• Add a short comment in tests that use placeholders so reviewers understand the fixture is synthetic.

Scanner notes

• Some compiled or binary assets (e.g., embedded base64 WASM blobs) can contain ASCII substrings that look like credentials and may trigger text-based secret scanners. If these assets are legitimate, either mark them in the scanner’s allowlist or exclude the directories in the scanner config.

If you find a leak

1. Rotate/revoke the key immediately.
2. Remove the secret from the history and force-push a cleaned branch if necessary.
3. Notify maintainers and follow your org’s incident response checklist.
