deployment-validator

Pre-deployment validation checks your Express app for common errors like misconfigured static files, route precedence issues, and missing environment variables before you push to Render. Run the validation to catch deployment failures early and ensure your app ships successfully on the first attempt.

Validation catches static file routing conflicts, incorrect route order, hard-coded paths, untracked git changes, missing required files, and environment variable inconsistencies. These checks prevent the frustrating scenario where your app works locally but fails after deployment.

Yes. Deployment validation is designed for Node.js and Express applications destined for Render or other production environments. It verifies git status, route configuration, build integrity, and environment setup specific to those deployment targets.

Validation provides specific fix suggestions including line numbers and exact issues to address. Review each identified problem—route order, static file paths, missing assets, or environment variables—and apply the recommended corrections before redeploying.

Yes. Running validation before each deployment catches regressions and new configuration issues introduced by recent changes. Integrate it into your pre-deployment workflow with `npm run validate:deploy` to prevent production errors.

Validation flags uncommitted or untracked files as a deployment blocker because they won't ship with your app. Commit or ignore these changes before deployment to ensure your production environment matches your tested codebase.
