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}]

BundlePhobia features and specs

  • Size Analysis

Possible disadvantages of BundlePhobia

  • Limited to npm
    BundlePhobia only analyzes packages available on npm, so developers using other package managers like Yarn might not find full compatibility.
  • Dynamic Challenges
    Dynamic dependencies or environment-specific issues are not accounted for, which might lead to inaccuracies in the real-world size analysis.
  • Cache Delay
    There may be a delay in updates due to caching, meaning newly published versions of packages may not be immediately visible on BundlePhobia.
  • Single Metric Focus
    The focus is largely on package size, without considering other important factors such as performance impact, security vulnerabilities, or overall package quality.
  • Requires Internet Connection
    Developers need an active internet connection to access BundlePhobia's web-based service, which can limit usability in offline environments.

  • Modern React Performance Without the Overhead
    Check packages on Bundlephobia before importing. A date-picker that pulls in 80 KB gzipped when you need one function is a problem you choose. - Source: dev.to / 3 months ago

  • Bundle size badges are just numbers
    There are two excellent services for estimating package size - Bundlephobia and Package Phobia. While the first calculates "bundle size", the second calculates "publish size" and "install size". The "install size" is the result of recursively summing up all the package dependencies. The result of such an evaluation may surprise. - Source: dev.to / 7 months ago
  • The hidden costs in your pacakge.json
    We can use bundlephobia.com to quickly check the โ€˜costโ€™ of adding a npm library to your bundle. Upon checking, it tells us moment.js clocks in at around 300KB, while date-fns is a much leaner 77KB:. - Source: dev.to / about 1 year ago

  • 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 / 10 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.
