react-native-polyfill-globals
Polyfills and patches missing or partially supported web and core APIs.
Motivation
There are several APIs which React Native does not support. When available, they usally are not spec-conformant. This package aims to fill that gap by providing polyfills and patches to said APIs.
As of React Native v0.63.3:
URLandURLSearchParamsare partially implemented.- https://github.com/facebook/react-native/blob/v0.63.3/Libraries/Blob/URL.js#L56
- https://github.com/facebook/react-native/blob/v0.63.3/Libraries/Blob/URL.js#L115
- Related discussions:
- https://github.com/facebook/react-native/pull/30188
- https://github.com/facebook/react-native/pull/25719
- https://github.com/facebook/react-native/issues/23922
- https://github.com/facebook/react-native/issues/24428
- https://github.com/facebook/react-native/issues/16434
- https://github.com/facebook/react-native/issues/25717

Usage
Polyfill all on demand
Import the polyfill function and call it whenever.
1import { polyfill } from 'react-native-polyfill-globals'; 2 3polyfill();
Polyfill all automatically
Add the following import to the top of your app's entry file, index.js, located at the root of your project.
1import 'react-native-polyfill-globals/auto';
Polyfill selectively
1import { polyfill as polyfillBase64 } from 'react-native-polyfill-globals/src/base64'; 2import { polyfill as polyfillEncoding } from 'react-native-polyfill-globals/src/encoding'; 3import { polyfill as polyfillReadableStream } from 'react-native-polyfill-globals/src/readable-stream'; 4import { polyfill as polyfillURL } from 'react-native-polyfill-globals/src/url'; 5import { polyfill as polyfillFetch } from 'react-native-polyfill-globals/src/fetch'; 6import { polyfill as polyfillCrypto } from 'react-native-polyfill-globals/src/crypto';
Apply patches
Patch files located at the patches directory provide additional polyfills and fixes.
Apply all at once with patch-package:
1$ npm install -D patch-package 2$ npx patch-package --patch-dir node_modules/react-native-polyfill-globals/patches
Apply invidually with Git:
1$ git apply --ignore-whitespace node_modules/react-native-polyfill-globals/react-native+0.63.3.patch
Apply invidually with patch:
1$ patch -p1 -i node_modules/react-native-polyfill-globals/react-native+0.63.3.patch
⚠️ Bundling
Note that Metro, React Native's bundler, at this time does not support tree-shaking nor dead code elimination. As such, beware that even if you apply polyfills selectively and don't use them at runtime, the code will be included in the production bundle regardless. If you don't need a given polyfill, do not import it at all.
