Quick start

Give ReadiumView a file and it renders the publication:

import { ReadiumView } from 'react-native-readium';

export function Reader({ path }: { path: string }) {
  return (
    <ReadiumView
      file={{ url: path }} // a local EPUB or PDF
      onLocationChange={(locator) => console.log(locator)}
      onPublicationReady={({ metadata, tableOfContents }) =>
        console.log(metadata.title, tableOfContents)
      }
    />
  );
}

On iOS and Android, file.url is a local path, such as a book your app downloaded into its documents folder. On web it's the URL of an unpacked EPUB's manifest.json; see Web.
