Metro Bundler vs rollup: What are the differences?

Metro Bundler: 🚇 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.; rollup: The next-generation JavaScript module bundler. 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.

Metro Bundler and rollup belong to "JS Build Tools / JS Task Runners" category of the tech stack.

Metro Bundler is an open source tool with 3.1K GitHub stars and 344 GitHub forks. Here's a link to Metro Bundler's open source repository on GitHub.

Decisions about Metro Bundler and rollup

We mostly use rollup to publish package onto NPM. For most all other use cases, we use the Meteor build tool (probably 99% of the time) for publishing packages. If you're using Node on FHIR you probably won't need to know rollup, unless you are somehow working on helping us publish front end user interface components using FHIR. That being said, we have been migrating away from Atmosphere package manager towards NPM. As we continue to migrate away, we may publish other NPM packages using rollup.

      What are some alternatives to Metro Bundler and rollup?
      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.
      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.
      Webpacker
      Webpacker makes it easy to use the JavaScript preprocessor and bundler Webpack to manage application-like JavaScript in Rails. It coexists with the asset pipeline, as the purpose is only to use Webpack for app-like JavaScript, not images, css, or even JavaScript Sprinkles (that all continues to live in app/assets).
