CLI tool for Size Limit
npm install size-limit alt="Size Limit logo by Anton Lovchikov" width="120" height="178">
Size Limit is a performance budget tool for JavaScript. It checks every commit
on CI, calculates the real cost of your JS for end-users and throws an error
if the cost exceeds the limit.
* ES modules and tree-shaking support.
* Add Size Limit to Travis CI, Circle CI, GitHub Actions
or another CI system to know if a pull request adds a massive dependency.
* Modular to fit different use cases: big JS applications
that use their own bundler or small npm libraries with many files.
* Can calculate the time it would take a browser
to download and execute your JS. Time is a much more accurate
and understandable metric compared to the size in bytes.
* Calculations include all dependencies and polyfills
used in your JS.

With [GitHub action] Size Limit will post bundle size changes as a comment
