How Baseline Can Help You Ship Less JavaScript
↗
Baseline lets teams audit their npm dependencies and replace libraries with native browser features when those features are safely supported.
Removing redundant libraries can shrink bundle size by tens of kilobytes, which speeds page loads and reduces data usage. The process requires checking real-world browser usage and potential polyfills, so teams must verify that native replacements won’t break users on older browsers. A repeatable audit gives a clear path to keep bundles lean as the web platform evolves.

Baseline classifies web features as Limited, Newly, or Widely available based on cross-browser support.
A typical mid-sized app often carries 60 to 90 KB of dependencies that browsers now implement natively.
Before dropping a library, teams should confirm audience support, evaluate any polyfill cost, and ensure the native API meets the original use case.
