Nodejs with Express server

• Remark, anything inside "<>" should be replaced by your desired folder name or number
• The "myapp1" and "express" can be also renamed, however to clear the confusion, just type as the command says:
  EG: replace cd <Where you want your app to be>/express/myapp1 with cd Documents/express/myapp1

Installing the generator for the Express app

npm install -g express-generator

for Unix-like OS (OSX, Linux, BSD, etc)

sudo npm install -g express-generator

It will ask for password, but won't display anything while user is typing, just type password and enter (This step is very confusing for someone who first time use command-line)

Generating a new app

cd <Where you want your app to be>
mkdir express
cd express
// express myapp1
express --view=pug myapp1  // Using the old command above will result in security warning about jade

The "myapp1" can be replaced with other names.

Before running , use the following command to install all the dependencies.

cd <Where you want your app to be>/express/myapp1
npm install
npm audit fix // Optional if there's system warning and you have paranoia

• In Raspberry Pi or MacOSX:

  cd <Where you want your app to be>/express/myapp1
  [PORT=<port>] DEBUG=myapp1:* npm start

• For windows

  cd <Where you want your app to be>/express/myapp1
  [set PORT=<port> & ]set DEBUG=myapp1:* & npm start

• Remark: the <port> should be replaced with a number between 1 and 65535, if you desire to change the port.
  • Port 1~1024 is blocked from use without admin right for some system, so if you see error it might be because of this.
