SVG
✓ import SVG from 'react-inlinesvg';
✗ const SVG = require('react-inlinesvg');
The primary component for inline SVG rendering. While CommonJS `require` might work in some transpiled environments, native ESM `import` is the recommended and modern approach for React applications.
useInlineSVG
✓ import { useInlineSVG } from 'react-inlinesvg';
Introduced in v4.3.0, this hook provides programmatic access to the SVG loading lifecycle. It's a named export.
CacheProvider
✓ import CacheProvider from 'react-inlinesvg/provider';
✗ import { CacheProvider } from 'react-inlinesvg';
Used to enable persistent browser caching for SVGs. This is a default export from a subpath, not a named export from the main package.
This quickstart demonstrates how to use the `SVG` component and `useInlineSVG` hook to load and display SVGs, including remote and local files, with loading indicators, error handling, caching via `CacheProvider`, and pre-processing for dynamic styling.

Errors
Common errors & fixes
'SVG' cannot be used as a JSX component. Its instance type 'InlineSVG' is not a valid JSX element. The types returned by 'render()' are incompatible between these types.
This TypeScript error typically indicates a version mismatch between `react-inlinesvg`'s types and your installed React/TypeScript versions, or incorrect import of the SVG component.
fixEnsure `react-inlinesvg` is up to date and compatible with your React version (check peer dependencies). You might need to add a `resolutions` field in your `package.json` for `@types/react` to enforce a specific version that aligns with your project.
Error: Failed to fetch SVG: ... Network request failed / CORS policy blocked.
Attempting to load a remote SVG from a different origin without proper CORS (Cross-Origin Resource Sharing) headers configured on the SVG's server, or a general network issue.
fixEnsure the server hosting the SVG file has appropriate CORS headers (`Access-Control-Allow-Origin`) configured to allow requests from your domain. Verify the URL is correct and accessible.
Warning: Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate.
Often related to infinite re-render loops caused by state updates within render or effects without proper dependency arrays, historically tied to the `loader` prop in older `react-inlinesvg` versions.
fixUpgrade to `react-inlinesvg@4.3.0` or newer. If the issue persists, review how state is managed in your `loader` component or within `onError`/`onLoad` callbacks to prevent unintended re-renders.
SVG content not displayed or styles incorrect when using `uniquifyIDs`.
Internal SVG references (like `url(#id)`) are not correctly resolving after `uniquifyIDs` processes the SVG, especially if a `<base>` tag is present in your HTML.
fixProvide the `baseURL` prop to the `SVG` component. The `baseURL` should be the base URL for resolving relative `url()` references within the SVG, often `window.location.href` or a specific asset path.
