RequireJS vs Selenium: What are the differences?

Developers describe RequireJS as "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. On the other hand, Selenium is detailed as "Web Browser Automation". Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.

RequireJS belongs to "Front End Package Manager" category of the tech stack, while Selenium can be primarily classified under "Browser Testing".

"Open source", "Modular script loader " and "Asynchronous " are the key factors why developers consider RequireJS; whereas "Automates browsers", "Testing" and "Essential tool for running test automation" are the primary reasons why Selenium is favored.

RequireJS and Selenium are both open source tools. It seems that Selenium with 14.7K GitHub stars and 4.92K forks on GitHub has more adoption than RequireJS with 12.2K GitHub stars and 2.3K GitHub forks.

According to the StackShare community, Selenium has a broader approval, being mentioned in 770 company stacks & 425 developers stacks; compared to RequireJS, which is listed in 914 company stacks and 184 developer stacks.

      What are some alternatives to RequireJS and Selenium?
      Browserify
      Browserify lets you require('modules') in the browser by bundling up all of your dependencies.
      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.
      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.
      Bower
      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.

      Nightwatchjs

      For our digital QA organization to support a complex hybrid monolith/microservice architecture, our team took on the lofty goal of building out a commonized UI test automation framework. One of the primary requisites included a technical minimalist threshold such that an engineer or analyst with fundamental knowledge of JavaScript could automate their tests with greater ease. Just to list a few: - Nightwatchjs - Selenium - Cucumber - GitHub - Go.CD - Docker - ExpressJS - React - PostgreSQL

      With this structure, we're able to combine the automation efforts of each team member into a centralized repository while also providing new relevant metrics to business owners.

      WebdriverIO

      I chose WebdriverIO and Appium to implement a E2E tests solution on a native mobile app. WebdriverIO goes well beyond just implementing the Selenium / Appium protocol and allows to run tests in parallel out of the box. Appium has the big advantage of supporting iOS and Android platforms, so the test codebase and tools are exactly the same, which greatly reduces the learning curve and implementation time.

      Maintaining and expanding automated regression tests is one of my primary responsibilities at CrowdTwist. We use Selenium to test the front-end parts of our platform.

      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).

      The RequireJS package manager is used by various web applications and services to manage dependencies on 3rd party libraries.

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

      Selenium is a great way to automatically test if a build is sane and can be deployed.

      RequireJS is the main component until Magento 2.2.x for frontend development.
