Embed Node.js App & Test

I already have a fully-working Node.js application and now I need it seamlessly embedded into my custom-built dynamic website. The goal is to make the app feel native to the site—same URL structure, consistent styling, and smooth data flow—without breaking any existing pages or functionality.

Once the integration is complete, I’d like a round of thorough testing. Please verify all routes and API calls, look for edge-case failures, and confirm that the app performs reliably under normal load. A concise test report outlining methods used, bugs found (if any), and fixes applied will serve as the acceptance criteria.

You can work directly with my Git repository and staging server; I’ll provide access as soon as we start. Let me know which test frameworks or automation tools you prefer so we stay aligned from day one.
