Summary
v28.0.0 added two Object.hasOwn calls on the init path. Object.hasOwn is ES2022. The library therefore requires Safari 15.4, Chrome 93, or Firefox 92. The release notes and the README do not state this requirement.
Call sites
packages/core/src/js/core/options.ts — option validation.packages/core/src/js/data/country-data.ts — dial-code to ISO2 map.
Evidence
I grepped the published tarballs for Object.hasOwn:
| Version |
Count |
| 24.0.0, 25.0.0, 25.3.1, 27.0.0 |
0 |
| 28.0.0, 29.0.0, 29.2.3 |
2 |
tsconfig.base.json sets "target": "ES2022". The output matches the target. This report concerns the documentation, not the target.
Request
- Add a "Browser support" section to the README. Name the minimum browser versions.
- Add one line to the v28.0.0 release notes. State that v28 raised the runtime baseline.
Both call sites also accept Object.prototype.hasOwnProperty.call(obj, key). That substitution restores the v27 baseline. Make it only if you want to keep support for older browsers.
Context
Dependabot bumped one project from 26.9.2 to 29.1.0. Customers on Safari 15.1 then lost the page. That project calls intlTelInput() inside a React effect, so the throw unmounted the whole form. We polyfilled Object.hasOwn on our side. We file this report so the next project finds the baseline in the docs.
