Feature Comparison: gzip-size vs webpack-bundle-analyzer vs source-map-explorer vs size-limit vs bundlewatch vs bundlesize

Purpose

  • gzip-size:

    Gzip-size is a utility that specifically measures the gzipped size of files, making it ideal for understanding how much data will be transferred over the network after compression.

  • webpack-bundle-analyzer:

    Webpack-bundle-analyzer provides an interactive visualization of your bundle's contents, making it easy to see the size of each module and dependency, which aids in identifying large or unnecessary packages.

  • source-map-explorer:

    Source-map-explorer analyzes the contents of your bundles by utilizing source maps, allowing you to see which files contribute to the final output size and helping to identify optimization opportunities.

  • size-limit:

    Size-limit is a tool that allows you to set size limits for your bundles and will fail your builds if they exceed those limits, helping to enforce performance standards in your project.

  • bundlewatch:

    Bundlewatch tracks bundle size changes over time, providing a historical view of size metrics. It is designed for teams that need to monitor and review bundle size changes across multiple builds.

  • bundlesize:

    Bundlesize is primarily focused on enforcing size limits for your bundles, ensuring that they do not grow unexpectedly during development. It integrates easily into CI/CD workflows to prevent size regressions.

Integration

  • gzip-size:

    Gzip-size can be easily integrated into build scripts or used as a standalone CLI tool, making it flexible for various development environments.

  • webpack-bundle-analyzer:

    Webpack-bundle-analyzer is designed to work directly with Webpack, providing a plugin that can be added to your Webpack configuration for real-time analysis during the build process.

  • source-map-explorer:

    Source-map-explorer can be run as a CLI tool or integrated into build processes to analyze bundles after they are generated, providing insights into the final output.

  • size-limit:

    Size-limit can be configured to work with various build tools and frameworks, including Webpack, Rollup, and Parcel, allowing for easy integration into existing projects.

  • bundlewatch:

    Bundlewatch can be integrated with GitHub Actions, CircleCI, and other CI/CD tools to track and report bundle size changes automatically, providing notifications when limits are exceeded.

  • bundlesize:

    Bundlesize integrates seamlessly with CI/CD systems like Travis CI and GitHub Actions, making it easy to enforce size limits as part of your development workflow.

Output

  • gzip-size:

    Gzip-size outputs the gzipped size of specified files, providing a straightforward metric for understanding the impact of compression on file sizes.

  • webpack-bundle-analyzer:

    Webpack-bundle-analyzer generates an interactive HTML report that visualizes the size of each module in your bundle, allowing for easy exploration and identification of large dependencies.

  • source-map-explorer:

    Source-map-explorer outputs a detailed analysis of the bundle, showing which files contribute to the size and how much space they occupy, helping to pinpoint optimization targets.

  • size-limit:

    Size-limit outputs clear messages indicating whether the bundle size exceeds the defined limits, helping developers quickly identify issues during the build process.

  • bundlewatch:

    Bundlewatch provides detailed reports on bundle size changes, including visualizations and historical data, allowing teams to track trends over time.

  • bundlesize:

    Bundlesize outputs simple pass/fail results based on the defined size limits, making it easy to see whether your bundles are within acceptable sizes at a glance.

Learning Curve

  • gzip-size:

    Gzip-size is very easy to use, requiring just a simple command to measure file sizes, making it accessible even for beginners.

  • webpack-bundle-analyzer:

    Webpack-bundle-analyzer is easy to use for those familiar with Webpack, as it integrates directly into the build process. The interactive visualizations also make it easy to understand the output.

  • source-map-explorer:

    Source-map-explorer may require some familiarity with source maps, but its CLI interface is intuitive, allowing developers to quickly analyze their bundles.

  • size-limit:

    Size-limit has a moderate learning curve, as it requires some understanding of configuration files, but its clear documentation helps ease the process.

  • bundlewatch:

    Bundlewatch is also user-friendly, with straightforward configuration options and clear documentation, making it easy for teams to implement and start monitoring bundle sizes.

  • bundlesize:

    Bundlesize has a low learning curve, as it requires minimal configuration to get started. Developers can quickly set size limits and integrate it into their workflows without extensive setup.

Use Cases

  • gzip-size:

    Gzip-size is perfect for quick checks of individual files or assets, especially during the development phase when optimizing specific resources for delivery.

  • webpack-bundle-analyzer:

    Webpack-bundle-analyzer is excellent for visualizing and optimizing Webpack bundles, making it easier to identify large modules and dependencies that can be refactored or removed.

  • source-map-explorer:

    Source-map-explorer is useful for developers looking to optimize their code by understanding which parts of their application contribute most to the bundle size, enabling targeted improvements.

  • size-limit:

    Size-limit is great for projects that require a proactive approach to bundle size management, as it enforces limits directly in the build process to prevent oversized bundles.

  • bundlewatch:

    Bundlewatch is best suited for teams that frequently update their code and need to monitor bundle size changes closely to prevent regressions and maintain performance standards.

  • bundlesize:

    Bundlesize is ideal for projects where maintaining strict control over bundle sizes is crucial, such as large applications with many dependencies that need to ensure performance remains optimal over time.

How to Choose: gzip-size vs webpack-bundle-analyzer vs source-map-explorer vs size-limit vs bundlewatch vs bundlesize
  • gzip-size:

    Use gzip-size if you want a lightweight utility specifically focused on measuring the gzipped size of files. It is useful for quick checks and can be integrated into build processes to ensure that the final output remains optimized for delivery over the web.
