Installing Gulp

First we need to run PowerShell and run as Administrator
Before install gulp need to install Node and npm (Node package management)
  • Node
  • Npm
First check whether any old version is installed if so need remove that version. For that need to run this command

npm rm install gulp -g
(rm : remove)
(-g : globally )


Ones it's completed run command for install
npm install gulp-cli -g

Then create project and move to that folder

npm init ->Initialize a Project
This will prompt get some input from developer in this following order
Name:
Version:
Description:
entry point :(Project main file)
Test command:
Git repository :
Keyword : (tag related to project)
Author :

When finished above process package.json created.


What is package.json?

  • JSON file so easy to read
  • includes the packages and applications it depends on
  • Project metadata project's name, description, and author
  • allows the separation production dependencies and development dependencies 
  • devDependencies for development
  • dependencies for production 
Note :npm install <module> --save-dev this for install devDependencies
