Metro Bundler vs Webpack: What are the differences?

Developers describe Metro Bundler as "🚇 The JavaScript bundler for React Native". 🚅 Fast: We aim for sub-second reload cycles, fast startup and quick bundling speeds ⚖️ Scalable: Works with thousands of modules in a single application. ⚛️ Integrated: Supports every React Native project out of the box.. On the other hand, Webpack is detailed as "A bundler for javascript and friends". 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.

Metro Bundler and Webpack can be categorized as "JS Build Tools / JS Task Runners" tools.

Metro Bundler and Webpack are both open source tools. It seems that Webpack with 49.8K GitHub stars and 6.27K forks on GitHub has more adoption than Metro Bundler with 3.1K GitHub stars and 344 GitHub forks.

      What are some alternatives to Metro Bundler and Webpack?
      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.
      Grunt
      The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes. After you've configured it, a task runner can do most of that mundane work for you—and your team—with basically zero effort.
      Parcel
      Parcel is a web application bundler, differentiated by its developer experience. It offers blazing fast performance utilizing multicore processing, and requires zero configuration.
      Brunch
      Brunch is an assembler for HTML5 applications. It's agnostic to frameworks, libraries, programming, stylesheet & templating languages and backend technology.
      rollup
      It is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD.

      I use JavaScript these days and for few years I didn't have to use jQuery at all. I used to use it back in the days when IE8 and similar was a thing. But due to better browser support of native functions for DOM manipulation I could move to vanilla JavaScript. Most of the time, that's all I need to work with modals/accordions and similar. But I'm not saying that jQuery is bad. It was, and still is a great tool. Some of it's features are available in all browsers nowadays so it is not so important as it used to be. But jQuery has still advantage for example in it's selector engine, some DOM selections which are easy in jQuery are a bit more difficult in vanilla JS (you have to create some helper functions or use some 3rd party library to help you with that), but to be honest I needed this on very few occasions. So it really depends on your project (supported browses, plain JS or some bundling - gulp, Webpack, whether you plan to use modules etc.). Hope this helps.

      #Merge
      #WebPackDevServer

      Using Webpack is one of the best decision ever. I have used to Grunt and gulp previously, but the experience is not the same, and despite I know there are other bundlers like Parcel, Webpack gives me the perfect balance between automatization and configuration. The ecosystem of tools and loaders is amazing, and with WebPack #merge, you can modularize your build and define standard pieces to assemble different build configurations. I don't like processes where you cannot see their guts, and you have to trust in magic a little bit too much for my taste. But also I don't want to reinvent the wheel and lose too much time configuring my build processes. And of course, I love #WebPackDevServer and hot reloading.

      How developers use Metro Bundler and Webpack

      Webpack is the best bundler. Period.

      Yes, it has a(n arguably) messy documentation, and a steep learning curve; but once you get the hang of it, there is nothing you cannot do with it.

      Use it and you don’t have to use any other bundler at all.

      It has a vivid ecosystem, and great plugin support.

      My preferred build tool; allows me to bundle my JSX, JS, CSS files for easy access and I can pass the bundle through my node server for server side rendering.

      Flexible building and compiling of source for browser consumption, mainly for JS, but experimenting a little with CSS (although I prefer StylusJS for CSS).

      We use this to optimise the delivery of the client-side for our revised Admin System, so it's able to be delivered to browsers as efficiently as possible.

      Webpack compiles files to bundles with source maps. Using Webpack you can use the latest features (ES6) and have it compiled to compliant js.
