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}]

esbuild features and specs

  • Speed
    esbuild is known for its blazing-fast performance because it is written in Go and optimized for efficiency. This makes it significantly faster than many other popular build tools.
  • Simplicity
    esbuild has a minimalistic and straightforward configuration, making it easy to set up and use without needing to navigate through complex configuration files.
  • Tree Shaking
    esbuild supports tree shaking, which helps in eliminating dead code, thereby resulting in smaller bundle sizes and improved performance.
  • TypeScript Support
    esbuild has built-in support for TypeScript, allowing developers to seamlessly integrate TypeScript into their build process without needing additional configuration.
  • CommonJS and ES Module Support
    esbuild supports both CommonJS and ES modules, providing flexibility in how modules are imported and exported.
  • Bundling
    esbuild can bundle multiple JavaScript files, resolving dependencies and optimizing the output, which is beneficial for production-ready applications.

Possible disadvantages of esbuild

  • Limited Plugin Ecosystem
    Compared to more mature tools like Webpack or Rollup, esbuild has a relatively smaller ecosystem of plugins, which might limit some advanced customization and integration capabilities.
  • Less Mature
    As a newer tool, esbuild might have less extensive community support and fewer resources such as tutorials and documentation compared to older and more established build tools.
  • Feature Parity
    While esbuild covers many essential features, it may lack some advanced features found in other build tools, potentially requiring additional tools or workarounds for complex scenarios.
  • Non-Configurable Output
    esbuild's approach to simplicity sometimes means less configurability compared to other tools. This might be restrictive for projects that require highly customized or specific build outputs.
  • Source Map Support
    While esbuild does support source maps, its support might be less comprehensive compared to some other build tools, potentially causing issues during debugging.

  • How To Build An API With Node, Without Additional Framework (SQL Included)
    TypeScript requires a compilation step before execution. Although Node "is starting" to offer native support for .ts, I opted here for ESBuild (an ultra-efficient bundler), to generate a JavaScript file executable simply with Node: esbuild src/index.ts --bundle --format=esm --outfile=dist/index.js --platform=node --target=node22.14 && node dist/index.js. - Source: dev.to / 3 months ago

  • Why and how to optimize your Lambda
    I recommend using NodeJS, not because it fits the event-driven, non-blocking model, but because it is very well-suited for reducing file size by bundling the code. Esbuild is a great tool to bundle your Lambda. It is already included in the CDK construct NodeJSFunction when using AWS CDK, and you don't need source maps, at least not in production. - Source: dev.to / 4 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 / 5 months ago

  • TANStack Query
    Still, I'm not really sure about its dependencies: it lists react and @tanstack/react-query (as opposed to @tanstack/query-core) and bundlejs reports 124KB gzipped. Also, while using it, you still need to refer to their react docs (that documentation is really good and has a lot of examples) but not everyone will be thrilled about checking a react documentation when they're using an angular package.

  • Jest not recommended to be used in Node.js due to instanceOf operator issues
    It's somewhere in between. React as a lib and architecture _is_ platform-agnostic. The core logic is defined in the `react-reconciler` package. It contains all the implementation of rendering components, diffing trees, managing state, and running effects, as well as all the "Suspense" implementation. However, the way `react-reconciler` works is that it's built _into_ each platform-specific renderer... - Source: Hacker News / over 2 years ago
