Im running express on windows 8. I ran the command
>express app
after i ran the command to install dependencies
>cd app && npm install
after i attempted to run the app using the given command
>DEBUG=my-application ./bin/www
but I received the error message
'Debug' is not recognized as an internal or external command,
operable program or batch file.
any ideas on how to fix this?
Some background info, I successfully installed node.js from their website. I attempted to install express usings the commands
>npm install
when that didnt work i followed the instuctions on this website https://coderwall.com/p/mbov6w. when that didnt work i used the following command and it worked
npm install -g express-generator#3
i also made my own package.json and app.js based off the express website and i am now stuck.

Answer 1

For Windows : change your start command in the package.json file to
"scripts": {
"start": "set DEBUG=my-application & node ./bin/www"
}
then you can run npm start.
There's no need to set the DEBUG environment variable in your cmd window first.

Answer 2

First, you must set DEBUG as a environment variable:
set DEBUG=my-application
then, you can run the app:
node bin/www

Answer 3

In your root folder of your project you have to run this command
For Windows:
set DEBUG=express:* & node bin/www

Answer 4

For windows environments you need to use SET VARIABLE for example
"scripts" : {
"start" : "SET DEBUG=app & node ./bin/www"
}
That will help you with windows env but if you want to use cross platform I recommend to install this library cross-env that library will help you to set variables for windows and linux environments.
And the json should look like this:
"scripts" : {
"start" : "cross-env DEBUG=app & node ./bin/www"
}
I was having same issue and this help me!

Answer 5

use this settings on your package.json
For window Users..
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "set DEBUG=app & node app.js"
},
For Mac Users
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "DEBUG=app node app.js"
},
app is your-app-name such as [app.js][server.js] etc.

Answer 6

Follow the following steps for windows:
Go to your application i.e. cd app
npm install
set DEBUG=app
npm start
It will start listening on port 3000 by default.

Answer 7

This fixed my issue :
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node src/index.js"
}

Answer 8

The below command is for the windows users running on Git Bash with nodemon.
"scripts": {
"start": "node index.js",
"dev": "SET DEBUG=app:* & nodemon index.js"
}
