URL

Important: The Vega SDK supports many of the React Native version 0.83 components and APIs. You can use the supported components and APIs in the same manner as an ordinary React Native app. This page lists a specific React Native feature supported by the Vega SDK and contains React Native V0.83 documentation from the reactnative.dev website created by Meta and other contributors and licensed under the Attribution 4.0 International License. For more information about React Native V0.83, see the React Native documentation, version 0.83. For the most current feature information, see the Release Notes.

The global URL class implements the URL Web API, supporting all standard properties: hash, host, hostname, href, origin, password, pathname, port, protocol, search, searchParams, and username.

Trailing slash bug fix

Vega's URL implementation includes a fix for a known React Native issue #24428 where URLs incorrectly received automatic trailing slashes. For example, in stock React Native, a URL like [https://example.com](https://example.com) was incorrectly converted to [https://example.com/,](https://example.com/,) potentially causing 404 errors or unexpected behavior.

This issue has been resolved in React Native for Vega, so developers can use the URL class without needing third-party polyfills such as react-native-url-polyfill.

Example

This example demonstrates the fixed trailing slash issue.

const url = new URL('https://example.com/path/to/resource.png');
console.log(url.href); // Correctly outputs: https://example.com/path/to/resource.png
