It appears that whenever a re-render runs because of the document prop constantly being a new reference, something breaks inside. So if you memoize the object that is being passed to the document prop, it works.

@NordlingDev Please can you explain with an example?

NordlingDev commented 2 years ago

@paragraje Instead of passing a new object for the document prop on each render, create a memoized object:

const imageLink = Router().generate('app_document_getdocumentpage', { pageId: document?.pages[0]?.id });
const doc = React.useMemo(() => ({ url: imageLink }), [imageLink]);

return (
  <PDFViewer document={doc} canvasCss={styles.pdfCanvas} />
);

This way you keep the same object reference at all times, unless imageLink changes.

HI I try to implement pdf-viewer-reactjs to Load PDF from base64 string. But, I am getting the below error,

Error while reading the pages ! TypeError: Cannot set properties of null (setting 'height').

This is my code: <PDFViewer document={{ base64: source.base64 }} /> Please help me to resolve. Please refer any documentation to explore pdf-viewer-reactjs.

Thnak you.
