Bower VS NPM

If you are confused between Bower and NPM then this is definitely for you. In short Npm and Bower are both Project dependency management tools. Below are some basic differences between these two-

  • Used for-
    • NPM is most commonly used for managing Node.JS modules, but it works for the front-end too when combined with Browserify etc..
    • Bower is front-end Package Manager and used for managing front end components jQuery, Bootstrap and so on.
  • Dependency-
    • NPM does nested dependency tree means packages we added in our project can also be dependent on other dependencies and those can further have more dependencies and so on. So, NPM installs dependencies for each package separately, and as a result makes a big package dependency tree(node_modules\babel-core\node_modules\…) where there could be several version of the same package.  For client-side JavaScript this is unacceptable: you can’t add two different version for jQuery or any other library to a page.The reason many projects use both is that they use Bower for front-end packages and npm for developer tools like Yeoman, Grunt, Gulp, JSHint, CoffeeScript, etc.
    • Bower requires a flat dependency tree No nested versioning of packages. With Bower each package is installed once (jQuery will always be in the bower_components/jquery folder, regardless of how many packages depend on it) and in the case of a dependency conflict, Bower simply won’t install the package incompatible with one that’s already installed.
