My Express app on Node.js never responds to Postman requests. Below is a concise example:
const express = require('express');
const server = express();
server.use(express.json());
server.get('/ping', (req, res) => res.send('All Good'));
server.listen(4000, () => console.log('Server active'));
Based on my experience, when an Express server fails to respond, it often involves issues outside the basic code. I encountered a similar situation where the code was correct, but the issue was with the environment; for instance, port misconfiguration or interference from another service was preventing a proper response. I made sure that my firewall settings allowed traffic on the required port and double-checked that Postman was correctly targeting the server’s address. Additionally, verifying that all environment variables were set up correctly helped me pinpoint the underlying problem.
try checkin if u r using the right method; my server got hung cause i sent post on a get route. a few typos in url could also block it, so double check postman settings.
hey, maybe the port is already in use? i once had similar issue cuz of a misrouted endpoint. have you checked your network logs to see if reqs are even gettin there?
Based on similar experiences, it is important to ensure that the server is properly set up even when the code appears correct. There were occasions when the issue stemmed from an unnoticed mistake in the configuration or an overlooked middleware order. In one case, I discovered that the absence of proper error handling masked underlying issues, resulting in an apparent unresponsiveness. I recommend confirming that the server correctly binds to the designated port and experimenting with simple requests to verify proper response handling. Additional logging can also assist in identifying any steps where the request may be failing.
hey, check if cors isnt blocking your reqs. added the cors middleware and it worked for me. sometimes its not the code but the server settings or network configs. double chk and try again, might be the missing link.
