Integrate NodeJS server into Cloudflare worker

Question

I need help integrating a NodeJS server that handles authentication into my workers index.js file. I am trying to respond to specific HTTP requests in the following code snippet:

catch (e) {
    if (!DEBUG) {
      try {
        // Add code here
      }
    }
}

Here is an example HTTP request that needs to be added to index.js: app.post('/login', async (req, res) => {//Logic}

Any help would be greatly appreciated!
