size-limit
Advanced tools
Package description
Size Limit is a performance monitoring tool for JavaScript projects. It helps you keep your project within a specific size limit by analyzing the size of your JavaScript bundles and providing warnings when the size exceeds the specified limit.
Bundle Size Analysis
This feature allows you to specify the path to your JavaScript bundle and set a size limit. Size Limit will analyze the bundle and ensure it does not exceed the specified limit.
module.exports = [
{
path: 'dist/bundle.js',
limit: '500 KB'
}
];Custom Configurations
You can customize the analysis by enabling gzip compression or disabling the running of the bundle. This provides more flexibility in how you measure the size of your bundles.
module.exports = [
{
path: 'dist/bundle.js',
limit: '500 KB',
gzip: true,
running: false
}
];Multiple Bundles
Size Limit supports analyzing multiple bundles in a single configuration. This is useful for projects with multiple entry points or output files.
module.exports = [
{
path: 'dist/bundle1.js',
limit: '300 KB'
},
{
path: 'dist/bundle2.js',
limit: '200 KB'
}
];Webpack Bundle Analyzer is a tool that visualizes the size of webpack output files with an interactive zoomable treemap. It provides a detailed breakdown of the bundle contents, making it easier to identify large modules and optimize the bundle size. Unlike Size Limit, it focuses more on visualization and detailed analysis rather than enforcing size limits.
Bundlesize is a tool that lets you set size limits for your JavaScript bundles and reports the size of the bundles in your CI/CD pipeline. It is similar to Size Limit in that it enforces size limits, but it integrates more tightly with CI/CD workflows and provides a simpler configuration.
Source Map Explorer analyzes JavaScript bundles using source maps to determine which files contribute to the bundle size. It provides a detailed breakdown of the bundle contents, similar to Webpack Bundle Analyzer, but it relies on source maps for its analysis. This makes it useful for understanding the impact of individual source files on the final bundle size.
