Greptile Overview

Greptile Summary

This PR updates the tsdown build tool from v0.17.0 to v0.19.0, which includes several breaking changes. However, after thorough analysis of the codebase and configuration, none of the breaking changes affect this project:

Breaking Changes Review

v0.19.0 Breaking Changes:

✅ debugLogs renamed to debug - Not used in tsdown.config.ts
✅ silent option removed - Not used in tsdown.config.ts
✅ debug renamed to devtools - Not used in tsdown.config.ts
✅ exports.legacy option introduced - Project does not use tsdown's exports feature; package.json exports are manually managed
✅ exports.exclude extension behavior change - Project does not use tsdown's exports feature
✅ Auto-fill types only with exports.legacy - Project does not use tsdown's exports feature

Configuration Analysis

The project's tsdown.config.ts uses a straightforward dual-format build configuration:

ESM build: Unbundled with external dependencies
CJS build: Bundled with noExternal: ['iron-webcrypto', 'uint8array-extras']

The configuration does not use any of the deprecated or renamed options, and does not rely on tsdown's automatic package.json exports generation.

Dependency Updates

The update also brings:

rolldown: v1.0.0-beta.53 → v1.0.0-beta.59 (underlying bundler)
@oxc-project/types: v0.101.0 → v0.107.0

These are incremental updates to the bundling infrastructure that should not introduce breaking changes to the build output.

Recommendation

This is a safe dependency update that brings performance improvements and bug fixes without affecting the project's build configuration or output.

Confidence Score: 5/5

This PR is safe to merge with no risk - it's a straightforward dependency update that doesn't affect the build configuration or output
Score of 5 reflects that: (1) None of the breaking changes in tsdown v0.19.0 affect this project's configuration, (2) The project does not use any deprecated or renamed options, (3) The project manually manages package.json fields rather than using tsdown's exports feature, (4) The underlying dependency updates (rolldown, @oxc-project/types) are incremental beta versions with no known breaking changes, (5) The build configuration in tsdown.config.ts remains unchanged and compatible
No files require special attention - this is a clean dependency version bump in package.json and package-lock.json with no configuration changes needed
