Case
- Goal
- Configure Yoga.Config with useWebDefaults and pointScaleFactor to apply CSS flexbox defaults and subpixel rounding across parent and child nodes HOW
- Packages
- yoga-layout 3.2.1
- Environment
- node
- Created
- 2026-08-16T07:08:30Z
Contract
- assert yoga-layout resolved version is 3.2.1
- assert default Config has useWebDefaults disabled (false) and default Node uses React Native defaults (flexDirection Column, flexShrink 0, alignContent FlexStart)
- assert Config with setUseWebDefaults(true) sets web defaults (flexDirection Row, flexShrink 1, alignContent Stretch)
- assert child Node does not inherit Config from parent upon insertion and retains flexShrink 0 unless created with the Config
- assert overflowing children in a fixed row fail to shrink under Yoga defaults (overflowing container to 300px width)
- assert overflowing children in a fixed row shrink to fit (100px each, 200px total) when created with useWebDefaults Config
- assert pointScaleFactor 1.0 rounds coordinates to integer pixel boundaries (10.6 to 11 and 10.4 to 10)
- assert pointScaleFactor 0.0 disables pixel snapping and preserves exact subpixel floating point values
- assert pointScaleFactor 2.0 snaps coordinates to half-pixel multiples (10.25 to 10.5 and 10.75 to 11.0)
- assert freeing root node with freeRecursive releases entire tree and Config.free releases config allocation
