Package Managers

Package – A package can be a GitHub shorthand, a Git endpoint, a URL, and more. Eg: bootstrap

  1. npm – node package manager
  2. bower – package manager for web
    • bower is a command line utility
    • has to be installed with npm
    • Installing bower: (-g installs it globally)
      • npm install -g bower
    • bower requires node, npm and git
    • bower init to initialize bower.json file
    • Installing packages with bower
      • bower install <package>
      • bower install <package> -S (for saving in bower.json)
      • bower install <package> -D (for saving in bower.json as devdependency)
    • Issues git not found event after having git client tool
      • solution:
        • locate your git.exe file
        • It’s usually located here – C:\Users\user\AppData\Local\GitHub\PortableGit_dGUID\cmd
        • GUID changes when the git gets updated
        • copy the path and paste it in command line
        • enter ‘git’ command, if you see git help options that means git is working
        • now copy the path, remove ‘.git.exe’ at the end and paste into PATH variable
        • close and reopen the command line and try entering git command again. If everything goes right, git works!
      • package.json file gets created with all dependencies. If not just enter, ‘npm init’ command
  3. composer – A dependency manager for php
    • Installing composer
      • https://getcomposer.org/download/
      • The installer will download composer for you and set up your PATH environment variable so you can simply call composer from any directory.
    • Installing packages with composer:
      • composer require twbs/bootstrap
    • For php
      • Eg:
        • composer require phpmd/phpmd
        • composer require –dev phpunit/phpunit
          • Using phpunit from commandline
            • .\vendor\bin\phpunit testFile.php
            • Same pattern of execution for other modules installed with composer
    • composer.json file gets created with all dependencies
