  • Feature Parity

rollup.js features and specs

  • Tree Shaking
    Rollup.js performs treeshaking to eliminate dead code, resulting in smaller bundle sizes. It analyzes the dependency tree and includes only the parts of the code that are actually used.
  • Output Formats
    Supports multiple output formats including ES modules, CommonJS, AMD, UMD, and IIFE. This makes it versatile for different use cases.
  • Plugins
    Rollup.js has a rich ecosystem of plugins that extend its functionality, such as code transformation, minification, and support for various types of modules.
  • Code Splitting
    Supports code splitting, allowing you to break your code into smaller chunks that can be loaded on demand. This improves performance for larger projects.
  • Efficient Bundling
    Offers efficient bundling by removing duplicates and ensuring that each module gets included only once, which contributes to reduced bundle size.
  • Minimal Configuration
    Generally requires minimal configuration to get started, focusing on simplicity and ease of use.

Possible disadvantages of rollup.js

  • Learning Curve
    Although relatively simple to use, there is still a learning curve associated with understanding its configuration and the plugin system.
  • Initial Build Time
    The initial build time can be slower compared to some other bundlers, particularly for larger projects.
  • Limited Built-in Features
    Rollup.js focuses on being a minimalist tool, so it lacks some of the built-in features that other bundlers may have. Often, additional functionality needs to be added via plugins.
  • Plugin Compatibility
    Not all plugins work seamlessly with Rollup.js, and there may be occasional compatibility issues, especially with plugins originally designed for other bundlers.
  • Node.js Ecosystem
    While Rollup.js excels in bundling for browsers, it is not as commonly used for Node.js applications compared to other tools like Webpack.
  • Community Size
    The community size is smaller compared to other bundling tools like Webpack, which can sometimes make finding solutions to issues more challenging.

Rollup v. Webpack v. Parcel
Rollup provides much simpler configuration over webpack 4 and has a host of pre-configured plugins that are a breeze to incorporate into your project. Rollup's also the fastest of the build tools period.

  • How do I display a markdown table on a website with go backend?
    So you're going to need a Markdown parser that produces HTML. But there's a question of where is the data coming from and where you you want to process it? If it's going to be all on the frontend like a text editor, use a JS library for it (a quick google search produces ShowdownJS). Source: over 2 years ago
  • Docusaurus first impression and stealing like an open sourcer
    Previously, I was required to implement the markdown support manually which meant that the use of public libraries was prohibited. My tool could only support limited styling elements such as header1, header2, links, bold and italics, but now I can finally let my tool have a full markdown support by using Showdown. - Source: dev.to / over 2 years ago
  • I made a full-stack portfolio site using Next.js and Tailwind!
    The first two ages are very heavy on content so I decided to use markdown and tailwind’s typography plugin for styling. I also used showdown to fetch the markdown and turn it into HTML. The code for the above can be found on the site’s GitHub repository. - Source: dev.to / over 2 years ago
  • Working on a no-code data notebook. You can quickly pull data from platforms like Stripe and do complex analysis without writing SQL, all within a Notion-style interface. Thoughts?
    I'm using https://github.com/showdownjs/showdown for the core rendering-markdown functionality, with a bunch of additional listeners etc on top of it to fit it into the notion-style UX! Hope that helps :). Source: over 2 years ago

  • Optimizing React Development with Vite🤩.
    6. Production-Ready Code Vite uses Rollup for production builds, which optimizes the code by bundling it efficiently, performing tree shaking, and minifying JavaScript. This results in smaller, optimized production builds that are ready for deployment. - Source: dev.to / 5 months ago
  • What is Evan You doing by creating VoidZero, and what are the issues with JS toolchains?
    Meanwhile, esbulid (developed in Go language, as introduced earlier) and rollup can also be used separately as packaging tools, and many third-party JS plugins are packaged using rollup. - Source: dev.to / 5 months ago
  • Node.js: A brief history of cjs, bundlers, and esm
    Npm packages dramatically sped up the productivity of developers by being able to leverage other developers' work. However, it had a major disadvantage: cjs was not compatible with web browsers. To solve this problem, the concept of bundlers was born. Browserify was the first bundler which essentially worked by traversing an entry point and "bundling" all the require()-ed code into a single .js file compatible... - Source: dev.to / 5 months ago
