'@tanstack/intent': patch
---

Minify the published build. The `dist` directory shrinks from 729 kB to 437 kB (40% smaller), and commands behave and print the same as before. Function and class names are kept, so a stack trace from installed code still names each function, but its positions now point into minified lines. The hook script that `intent hooks install` writes does not change.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Document the reported tree-shaking trade-off.

The PR reports that minification removes #__PURE__ annotations and may prevent downstream bundlers from dropping unused @tanstack/intent code. Add this potential bundle-size impact for library consumers.

Proposed changeset addition 
+Minification removes `#__PURE__` annotations, which may reduce tree-shaking when consumers bundle `@tanstack/intent`.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Review comment at @.changeset/minify-dist.md at line 5:
Update the changeset description to document that minification removes
`#__PURE__` annotations and may reduce downstream tree-shaking of
`@tanstack/intent`, potentially increasing consumer bundle sizes. Preserve the
existing description of minification behavior.
