Struggling to Parse Mailgun Webhook POST Data in Node

I’m having difficulty extracting POST parameters from a Mailgun webhook in my Node.js server. How can I convert the incoming form-data into JSON?

const http = require('http');
const srv = http.createServer((req, res) => {
  let result = '';
  if (req.method === 'POST') {
    req.on('data', chunk => result += chunk);
    req.on('end', () => console.log(result));
  }
});
srv.listen(3000);

hey, i switched to express and its body-parser solved my issues with mailgun posts. gives me the data as json without extra hassle. might be a good patch for you too.

I encountered a similar challenge when trying to parse Mailgun’s webhook POST data. In my case, using middleware to convert the incoming form-data into a JSON object made the process more streamlined. I ended up sticking with Node’s native modules along with a third-party form parser like multer or formidable, which greatly improved the reliability of data extraction. In my experience, these tools handle the quirks of multipart form data effectively while preserving all parameters. An upgrade to such a parser can minimize unexpected issues and simplify data handling in your application.

I too encountered difficulties when working directly with the Node.js HTTP module for parsing Mailgun webhook data. One approach that worked well in my project was to create a custom parser that collected data chunks and then processed them with the built-in querystring module. This allowed for converting the URL-encoded form data into a usable object without relying on Express. The custom middleware was straightforward and kept my project lean by avoiding unnecessary libraries. This method requires careful management of data events and error handling but can be quite efficient for simpler scenarios.

hey, i had the same prob. ended up trying busboy for parsing - made my code much less messy. hope it helps, cheers.

I encountered similar challenges and found that incorporating the multiparty library worked well for my requirements. Instead of switching to Express, I used multiparty to capture the POST data and convert it into a JSON object. Once the multipart form had been processed, I applied Node’s built-in modules to clean up and validate the entries. This approach allowed for a more direct handling of form data without heavy reliance on external frameworks. It required careful error checking but ultimately streamlined working with Mailgun webhook payloads.
