storage​

• Optional storage: ClientStorage

Storage implementation.

Default is window.localStorage (if available), this is the common implementation for use in the browser, or an in-memory storage implementation.

async function createPdf(docDefinition, tableLayouts, fonts) {
  return new Promise((resolve) => {
    pdfMake.createPdf(docDefinition, tableLayouts, fonts).getBlob(resolve);
  });
}
</script>

In Node.js applications:

import type { CustomTableLayout, TDocumentDefinitions, TFontDictionary } from 'pdfmake/interfaces';
function createPdf(
  docDefinition: TDocumentDefinitions,
  tableLayouts?: { [name: string]: CustomTableLayout },
  fonts?: TFontDictionary
): Promise<Buffer> {
  return new Promise((resolve, reject) => {
    const printer = new PdfPrinter(fonts ?? {});
    const pdfDoc = printer.createPdfKitDocument(docDefinition, { tableLayouts });
    const chunks: Uint8Array[] = [];
    pdfDoc.on('data', (chunk: Uint8Array) => chunks.push(chunk));
    pdfDoc.on('end', () => resolve(Buffer.concat(chunks)));
    pdfDoc.on('error', reject);
    pdfDoc.end();
  });
