nodemon not working properly
Solution 1
You're running express 4, which has the app.listen
call in a different file than app.js
. The command you're looking for is nodemon bin/www
(localhost
and 3000
are not needed in this scenario).
In fact, you can even run nodemon
with no args, and it'll read what command needs to be run from scripts.start
in package.json
(which express generates automatically).
Solution 2
Here's what I did to make nodemon update correctly:
nodemon index.js -L
The -L
flag stands for legacyWatch, here's an explanation from the official doc:
In some networked environments (such as a container running nodemon reading across a mounted drive), you will need to use the legacyWatch: true which enables Chokidar's polling.

Solution 3
In my case, I had to install nodemon globally. Use this command to do so..
npm install -g nodemon
If you're using Linux you may need to prefix the command with the sudo keyword for administration access..
sudo npm install -g nodemon
Solution 4
try running nodemon ./app.js 3000 or nodemon start 3000
Solution 5
Add following code in your code
app.js
app.listen(3000, function(){ console.log("info",'Server is running at port : ' + 3000); });
package.json
nodemon app.js
Then run npm start
from the command line.

I am running my nodejs app by
npm start
I just installed nodemon by
sudo npm install -g nodemon
so that i can get my server restarted when i save changes to files.But when i try to start the server, something like this
nodemon ./app.js localhost 3000 or nodemon start localhost 3000
I get this as output
LM-SJC-00871929:webapp gdeep$ nodemon ./app.js localhost 3000 28 May 23:34:30 - [nodemon] v1.1.1 28 May 23:34:30 - [nodemon] to restart at any time, enter `rs` 28 May 23:34:30 - [nodemon] watching: *.* 28 May 23:34:30 - [nodemon] starting `node ./app.js localhost 3000`
but when i go to my webpage, i get
Oops! Google Chrome could not connect to localhost:3000
. What am i doing wrong?App.js here http://collabedit.com/t35dy
