perf: minify the published build by LadyBluenotes · Pull Request #328 · TanStack/intent

LadyBluenotes · 2026-10-04T23:11:52Z

🎯 Changes

The published build is now minified, with function and class names kept.
dist goes from 729,431 to 437,083 bytes (40% smaller; 25% smaller as a per-file gzip sum). The packed tarball goes from 242,497 to 192,755 bytes, and the unpacked package from 897,051 to 604,703 bytes.
Speed does not get worse. A cold intent list --json --no-notices, intent validate, or intent stale process is 1 to 2 ms faster; the warm benchmarks are unchanged.
Twelve built commands give identical stdout, stderr, and exit codes. The hook script and the hook configuration that intent hooks install writes are byte-identical to the ones the current build writes.
Names are kept (keepNames for the compressor and the mangler), so the name of each public export and the function names in a stack trace stay the same. Full mangling would save a further 32 kB and would rename them.
Costs: each chunk is now one long line, so stack positions point into minified lines and an uncaught error prints that line before the stack. The #__PURE__ annotations are removed, which can reduce tree-shaking for a project that bundles @tanstack/intent.
Adds a patch changeset.

✅ Checklist

I have followed the steps in the Contributing guide.
I have tested this code locally with pnpm run test:pr (run pnpm build:all first).

🚀 Release Impact

This change affects published code, and I have generated a changeset.
This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

+'@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`.

📝 Committable suggestion

‼️ 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.
