Solution 1 - node.js
For just one run (from the unix shell prompt):
$ PORT=1234 node app.js
More permanently:
$ export PORT=1234
$ node app.js
In Windows:
set PORT=1234
In Windows PowerShell:
$env:PORT = 1234
Solution 2 - node.js
You can use cross platform solution https://www.npmjs.com/package/cross-env
$ cross-env PORT=1234
Solution 3 - node.js
use the below command to set the port number in node process while running node JS programme:
set PORT =3000 && node file_name.js
The set port can be accessed in the code as
process.env.PORT
Solution 4 - node.js
EDIT: Per @sshow's comment, if you're trying to run your node app on port 80, the below is not the best way to do it. Here's a better answer: https://stackoverflow.com/questions/6109089/how-do-i-run-node-js-on-port-80/27805105#27805105
Original Answer:
If you want to do this to run on port 80 (or want to set the env variable more permanently),
- Open up your bash profile
vim ~/.bash_profile - Add the environment variable to the file
export PORT=80 - Open up the sudoers config file
sudo visudo - Add the following line to the file exactly as so
Defaults env_keep +="PORT"
Now when you run sudo node app.js it should work as desired.
Solution 5 - node.js
The easiest way would be:
PORT=2222 node-dev app.js
