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}]

NPMScan features and specs

  • Ease of Use
    NPMScan provides a user-friendly interface that simplifies the process of monitoring NPM packages for vulnerabilities, making it accessible even to users with limited technical expertise.
  • Comprehensive Vulnerability Database
    It leverages a robust database of known vulnerabilities, enabling users to identify and address potential security risks in their projects efficiently.

    NPMScan offers continuous monitoring capabilities, alerting users in real time when new vulnerabilities are discovered in their dependencies.
  • Integration with Development Environments
    The tool integrates well with various development environments and CI/CD pipelines, enhancing developer productivity and ensuring security checks are part of the development lifecycle.

Possible disadvantages of NPMScan

  • Limited to JavaScript Ecosystem
    NPMScan is focused on NPM packages, so it is not suitable for projects involving other programming languages or package ecosystems.
  • False Positives
    Users may occasionally encounter false positive alerts, which can lead to unnecessary concern and investigation.
  • Dependency on External Databases
    The tool relies on third-party vulnerability databases, which could lead to delays in updates or inaccuracies if the databases are not maintained promptly.
  • Potential Performance Impact
    Continuous monitoring and scanning of dependencies might introduce performance overhead, particularly in large projects with numerous dependencies.

Analysis of NPMScan

Overall verdict

  • NPMScan is a useful security-focused tool for auditing npm packages and dependencies, helping developers identify vulnerabilities and malicious code before they reach production. While no single scanner is a complete security solution, it can be a valuable part of a broader supply-chain security workflow.

Why this product is good

  • Helps detect known vulnerabilities and suspicious behavior in npm packages
  • Supports proactive supply-chain security by catching risky dependencies early
  • Can integrate into development workflows to automate package auditing
  • Useful for reviewing third-party packages before adding them to a project

Recommended for

  • JavaScript and Node.js developers who rely heavily on npm packages
  • Security teams focused on software supply-chain risk
  • DevOps engineers integrating dependency scanning into CI/CD pipelines
  • Open-source maintainers who want to vet third-party dependencies

  • 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.
