@embedpdf/plugin-metadata

Metadata for EmbedPDF: reads and changes a document's title, author and your own fields.

This plugin comes with each EmbedPDF framework package. Import it from the one you use:

In React

A PDF carries information about itself: a title, an author, when it was made. Register metadataPlugin() to show it in your UI and let people change it:

title-field.tsx

import { useMetadata, useMetadataState } from '@embedpdf/react/metadata';

export function TitleField() {
  const { update, canUpdate } = useMetadata();
  const { metadata } = useMetadataState();

  return (
    <label>
      Title
      <input
        defaultValue={metadata?.title ?? ''}
        disabled={!canUpdate()}
        onBlur={(event) => update({ title: event.target.value })}
      />
    </label>
  );
}

What useMetadataState() gives you updates by itself: after your own changes, and on a shared document, after someone else's. Nothing is read when a document opens: the metadata loads the first time something asks for it, so a document nobody shows the properties of costs nothing.
