I installed nodemon.
I made changes to my code.
It is stuck at RESTARTING DUE TO CHANGES and doesn't restart the server.
Why is this happening and how to solve it?
>>index.js
const express = require('express');
const app = express();
app.get('', (req, res) => {
res.send('Hello, world!');
})
app.get('./help', (req, res) => {
res.send('Help Page!');
})
const port = 3000;
// const hostName = '127.0.0.1';
app.listen(port, () => {
console.log(`Server is listening on ${port}`);
});
>>package.json
{
"name": "app",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "nodemon index.js"
},
"author": "Sharjeel",

"dependencies": {
"express": "^4.17.1",
"nodemon": "^2.0.12"
}
}
The problem is with the latest version of the nodemon. The previous or older version runs completely fine without making any issue i.e. nodemon#2.0.7.

I'm using Windows and I've just installed nodemon 2.0.12 (added to path). Whenever I run a basic application it works it should until I save a file, then I receive the following error
My project is a basic express app:
const express = require('express')
const app = express()
const PORT = 3000
app.use("/", (req, res) => res.send('test'))
app.listen(PORT, function() {
console.log('Server started on port 3000')
})
My package.json is as follows
{
"name": "express.1",
"version": "1.0.0",
"description": "",
"main": "app.js",
"scripts": {
"dev": "nodemon app.j"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.17.1",
"nodemon": "^2.0.12"
}
}
What might be the reason for this?
Downgrading Nodemon to v2.0.7 seems to work. I don't understand why it broke in the first place.
index.js
// create an express app
const express = require("express");
const app = express();
// use the express-static middleware
app.use(express.static("public"));
// define the first route
app.get("/", function (req, res) {
res.send("<h1>Hello World!</h1>");
});
// start the server listening for requests
app.listen(process.env.PORT || 3000, () => console.log("Server is running..."));

Procfile
web: echo "I don't want a web process"
service: npm start
I have deployed it in heroku.
And the logs are showing as below
2021-06-22T13:16:11.346614+00:00 app[service.1]: ------------------------------------------------------------------
2021-06-22T13:16:11.371025+00:00 app[service.1]: Server is running...
But i am getting application error when i try to load the page.
It is working fine in local
Your web dyno maybe turned off by default.You need to turn it on inorder to run your heroku app
When declaring the middleware check whether that directory you have set is correct
app.use(express.static("public"));
If not then use __dirname to concatinate the correct directory like so
const public = path.join(__dirname, "../public")
then
app.use(express.static(public));
I just started learning nodejs and there is some weird error coming when I try to run nodemon server.js command.
Here is my server.js
const express = require("express");
const app = express();
const server = require("http").Server(app);
app.get("/", (req, res) => {
res.status(200).send("Hello World");
});
server.listen(3030);
My VScode terminal shows this but the server never starts.
Here is package.json
{
"name": "video-chat-app",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "nodemon server.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"ejs": "^3.1.6",
"express": "^4.17.1",
"peer": "^0.6.1",
"socket.io": "^4.1.2",
"uuid": "^8.3.2"
},
"devDependencies": {
"nodemon": "^2.0.7"
}
}
You don't need to use http, express is already enough to start a server.
const express = require("express");
const app = express();
app.get("/", (req, res) => {
res.status(200).send("Hello World");
});
app.listen(3030, ()=>{
console.log('Server is starting');
});
I'm trying to use nodemon on my macbook and whenever i run
nodemon <script.js>
It gives me this error:
address already in use <PORT NUMBER HERE>
Even if i'm running the script for the very first time. I've tried
npx kill-port <port>
But it doesn't work: it shows that a process was killed but when i try to run nodemon again, i get the same error.
Here's my package.json:
{
"name": "server",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "nodemon server.js"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"dotenv": "^10.0.0",
"express": "^4.17.1",
"nodemon": "^2.0.7"
}
}
My server.js:
const express = require("express");
const dotenv = require("dotenv");
const app = express();
dotenv.config();
const PORT = process.env.PORT;
app.get("/getRestaurants", (req, res) => {
console.log("Get All Restaurants");
});
app.listen(PORT, () => {
console.log(`Server is up on port ${PORT}`);
});
And my .env:
PORT = 4000;
What could be causing this? I'm on a M1 MBA with bigsur.
I am trying to use ES6 Modules to import Express. Although I added "type":"module" in my package.json. The error, SyntaxError: Cannot use import statement outside a module, still occurs. I am expecting an answer which does not require to convert into a .ejs extension since wanting to know what's wrong in my code rather than taking an alternative. Note: package.json & server.js are in the same directory.

const port = process.env.PORT || 9000
app.get('/', (req, res) => {

app.listen(port, () => {
console.log(`Listening on localhost: ${port}`)
});
