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}]

Analysis of Code Flex

Overall verdict

  • I don't have verified, specific information about 'Code Flex' at codeflex.pages.dev, as it appears to be a lesser-known or newly launched site hosted on Cloudflare Pages, and I cannot confirm its legitimacy, content quality, or safety without direct access to browse and verify it.

Why this product is good

  • Cloudflare Pages (.pages.dev) is a free hosting platform, meaning this could be anyone's personal, hobby, or unfinished project rather than an established product
  • No verifiable reviews, reputation data, or track record exists in available knowledge to assess trustworthiness
  • The name suggests it may be a coding practice, tutorial, or developer tool site, but its actual purpose, features, and quality are unconfirmed
  • Sites on free hosting subdomains generally warrant extra caution regarding data privacy and content reliability until proven otherwise

Recommended for

  • Users should independently verify the site by checking for an About page, contact information, HTTPS security, and third-party reviews before use
  • Not recommended for entering sensitive personal or payment information without further verification
  • Best approached with caution until legitimacy and purpose are confirmed through direct inspection or trusted reviews

  • 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.
