Compare bundlejs VS Webpack and see what are their differences

bundlejs logo bundlejs

A quick and easy way to bundle, minify, and compress (gzip and brotli) your ts, js, jsx and npm projects all online, with the bundle file size.

Webpack logo Webpack

Webpack is a module bundler. Its main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.

bundle is a quick and easy way to bundle your projects, minify and see it's gzip size. It's an online tool similar to bundlephobia, but bundle does all the bundling locally on you browser and can treeshake and bundle multiple packages (both commonjs and esm) together, all without having to install any npm packages and with typescript support.

If there is something I missed, a mistake, or a feature you would like added please create an issue or a pull request and I'll try to get to it. You can contribute to this project at okikio/bundle.

You can join the discussion on Github discussions or Twitter.

You can now use search queries in bundle, all you need to do is add this to the url
?q={packages}&treeshake={methods to treeshake}

e.g.
You want react, react-dom, vue, and @okikio/animate, but only want the Animate and toStr methods exported from @okikio/animate.

You would add this to the url bundlejs.com/?q=react,react-dom,vue,@okikio/animate&treeshake=[*],[*],[*],[{Animate,toStr}]

Webpack features and specs

  • Modular Bundling
    Webpack efficiently bundles all your modules (JavaScript, CSS, images, etc.) into manageable chunks, minimizing HTTP requests and enhancing load performance.
  • Code Splitting
    It allows splitting your codebase into 'chunks' which can be loaded on demand. This leads to faster initial page loads as only necessary chunks are loaded initially.
  • Hot Module Replacement (HMR)
    HMR allows you to update modules without needing a full refresh. This improves development speed and efficiency as live changes are instantly reflected in the application.
  • Advanced Configuration
    Webpack is highly configurable, accommodating various needs from simple setups to complex, custom configurations, making it versatile for different projects.
  • Strong Plugin Ecosystem
    There is a rich ecosystem of plugins available to extend Webpack's capabilities, such as minification, asset management, and more.
  • Tree Shaking
    Webpack supports tree shaking, a method to eliminate dead code from your bundle, resulting in more efficient, smaller output files.
  • Dependency Management
    It handles dependencies among modules effectively, automatically managing module load order and avoiding conflicts.

Possible disadvantages of Webpack

  • Complex Configuration
    Its extensive configuration options can be overwhelming, particularly for beginners, leading to a steep learning curve.
  • Build Time
    Complex configurations and large projects can result in slower build times, impacting development speed.
  • Documentation Issues
    Despite improvements, there are instances where Webpack's documentation might lack clarity, making it harder to find solutions for specific configurations.
  • Overhead for Simple Projects
    For small and simple projects, Webpack might be overkill, adding unnecessary complexity and setup time.
  • Compatibility Issues
    Occasionally, Webpack updates can lead to breaking changes, which may require significant adjustments to your configuration and codebase.

First impressions with Parcelย JS
From first impressions and experience, my take currently would be as follows. Webpack is generally going to be more flexible. It also places a bit more power in the developers hands to make bundling happen exactly as desired. That isnโ€™t to say you shouldnโ€™t use Parcel though. Where Parcel excels is the fact you donโ€™t configure it. You will still need to configure plugins for...

Webpack is the stable choice. You will not get fired for picking webpack. But you donโ€™t get as much stuff for free such as optimized bundles, and code splitting.

  • Show HN: Duper โ€“ The Format That's Super
    I think a neat route would be to use this as an authoring plugin in VS Code, like prettier: write Duper (or JSON5, or whatever), and then downlevel it to regular json automatically when pressing cmd-s. You wouldn't get to keep your comments (or they could be transformed to { "//": "comment text" }). Outside of that, it's tough to compete with JSON in the "human readable unschematized serialization format" market,... - Source: Hacker News / 9 months ago
  • I Built the Same App 10 Times: Evaluating Frameworks for Mobile Performance
    React's bundling system and published packages has gotten noticeably more complicated over time. First, there's the separation between the generic cross-platform `react` package, and the platform-specific reconcilers like `react-dom` and `react-native. All the actual "React" logic is built into the reconciler packages (ie, each contains a complete copy of the actual `react-reconciler` package + all the... - Source: Hacker News / 9 months ago
  • Zod 4
    These numbers don't reflect anything useful. This is the total size of the code in the package, most of which will be tree-shaken. In Zod's case, the package now contains three independent sub-libraries. I recommend plugging a script into bundlejs.com[0] to see bundle size numbers for a particular script [0] https://bundlejs.com. - Source: Hacker News / about 1 year ago

Webpack mentions (253)

  • History of JavaScript: Browser wars, ECMAScript, Node.js, TypeScript, and React
    In 2012, Webpack was released as an open-source JavaScript module bundler. It takes dependencies as input and builds a dependency graph, enabling developers to take a modular approach to web application development. This allowed them to import almost anything to client-side code and, over time, became the foundation of the build process for React, Angular, Vue, and many other frameworks. - Source: dev.to / 9 days ago
  • Next.js vs Remix: What's the Difference?
    From a developer experience perspective, it's worth noting that Next.js was built using webpack for bundling, which has struggled to maintain performance. Therefore, when changing something in the code, reload times can be very slow. For this reason, the Next.js team has been working on getting full compatibility on its own bundler, Turbopack. As of Next.js 14, Turbopack is still considered beta but is much faster... - Source: dev.to / 2 months ago
  • Claude Code's Source Didn't Leak. It Was Already Public for Years.
    The reality is simple: minification was never security. It's a size optimization that bundlers like esbuild, Webpack, and Rollup do by default. Variable renaming slows down human readers but LLMs read minified code like you read formatted code. - Source: dev.to / 4 months ago
  • React Server Components without Next.js - what are the real alternatives today?
    There are also no-framework approaches. These rely directly on React-provided packages and low-level integrations with bundlers like Webpack or experimental support in tools like Bun. While technically possible, these setups are fragile. React explicitly does not guarantee stability of these internal APIs. Any team choosing this route must accept ongoing maintenance risk. - Source: dev.to / 5 months ago
  • Workspaces, react and vite. A real-world case study for managing duplicate libraries.
    Before addressing the solution, it's useful to contextualize the role of the bundler. In a modern frontend architecture, the bundler (such as webpack, rollup, or vite) has the task of traversing the application's dependency graph, resolving each import statement, to combine modules and assets into static files optimized for browser execution. - Source: dev.to / 8 months ago
