Bower vs RequireJS: What are the differences?

Bower: A package manager for the web. Bower is a package manager for the web. It offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat; RequireJS: JavaScript file and module loader. RequireJS loads plain JavaScript files as well as more defined modules. It is optimized for in-browser use, including in a Web Worker, but it can be used in other JavaScript environments, like Rhino and Node. It implements the Asynchronous Module API. Using a modular script loader like RequireJS will improve the speed and quality of your code.

Bower and RequireJS belong to "Front End Package Manager" category of the tech stack.

"Package management", "Open source" and "Simple" are the key factors why developers consider Bower; whereas "Open source", "Modular script loader " and "Asynchronous " are the primary reasons why RequireJS is favored.

Bower and RequireJS are both open source tools. Bower with 15.2K GitHub stars and 1.97K forks on GitHub appears to be more popular than RequireJS with 12.2K GitHub stars and 2.3K GitHub forks.

According to the StackShare community, Bower has a broader approval, being mentioned in 803 company stacks & 395 developers stacks; compared to RequireJS, which is listed in 916 company stacks and 185 developer stacks.

    What are some alternatives to Bower and RequireJS?
    npm
    npm is the command-line interface to the npm ecosystem. It is battle-tested, surprisingly flexible, and used by hundreds of thousands of JavaScript developers every day.
    Yarn
    Yarn caches every package it downloads so it never needs to again. It also parallelizes operations to maximize resource utilization so install times are faster than ever.
    Webpack
    A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows to load parts for the application on demand. Through "loaders" modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
    gulp
    Build system automating tasks: minification and copying of all JavaScript files, static images. More capable of watching files to automatically rerun the task when a file changes.
    NuGet
    A free and open-source package manager designed for the Microsoft development platform. It is also distributed as a Visual Studio extension.

    Bower was used for a small amount of package management. npm was used everywhere but a few edge cases that only worked with Bower.

    Used Require.js to make the application modular. It provides better dependency management with asynchronous loading of scripts.

    No real definitive reason, I find it to be the most natural way to import libraries and code in nodejs (prior to ES6 / import).

    Very nice way to structure a project, as long as you know it will not be a hybrid app.
