How to use NPM commands behind the PROXY

🛠 Step to access to use npm commands behind the PROXY 🛠

Set SSL false by executing this command:

npm config set registry http://registry.npmjs.org/

Then, Get any one of the below:
1. User-specific - username:password@proxy.example.com:1431 (User Proxy)

It will automatically download and install all its dependencies.

to run project execute below npm command

ng serve -o

to extract output files execute below command

ng build  [this is for development]

ng build --prod [this is for production]
