Pdf not saved (in Device file ) in React Native

[vipulparmarmt]

What were you trying to do?

I have trying to save pdf by doing below code but can't able to save the modifed pdf on local device of android and ios in React Native

How did you attempt to do it?

// Code of Save the Edited Pdf file in local device import {degrees, PDFDocument, rgb, StandardFonts} from 'pdf-lib'; import RNFS from 'react-native-fs';

const editPdf = async () => { const url = 'https://pdf-lib.js.org/assets/with_update_sections.pdf'; const arrayBuffer = await fetch(url).then((res) => res.arrayBuffer()); const pdfDoc = await PDFDocument.load(arrayBuffer);

// Embed the Helvetica font
const helveticaFont = await pdfDoc.embedFont(StandardFonts.Helvetica);

// Get the first page of the document
const pages = pdfDoc.getPages();
const firstPage = pages[0];

console.log('firstPage====>', firstPage);

// Get the width and height of the first page
const {width, height} = firstPage.getSize();

// Draw a string of text diagonally across the first page
firstPage.drawText('This text was added with JavaScript!', {
  x: 5,
  y: height / 2 + 300,
  size: 50,
  font: helveticaFont,
  color: rgb(0.95, 0.1, 0.1),
  rotate: degrees(-45),
});

const pdfBytes = await pdfDoc.save();

const path = RNFS.DownloadDirectoryPath;

RNFS.copyFile(pdfBytes, path);

console.log('Saved pdf=====>', pdfBytes);

};

Above i have written the whole code of tying to edit the pdf file in react native using this package and saved to local files on android and ios

Using this method you can save The pdf file on Your local device android and ios ` import RNFetchBlob from 'react-native-blob-util';

const pdfBytes = await pdfDoc.save();
const pdfDataUri = await pdfDoc.saveAsBase64({dataUri: true});

   savePdfFile(pdfDataUri)

  const savePdfFile = (pdfUrl: string) => {
const dirs = RNFetchBlob.fs.dirs;
console.log('Saved Pdf Files====>', dirs);
const filePath = `${dirs.DownloadDir}/${new Date().toISOString()}.pdf`;
RNFetchBlob.fs
  .writeFile(filePath, pdfUrl.split(',')[1], 'base64')
  .then(() => {
    console.log('Saved Successfully====>');
  })
  .catch((err) => {
    console.log('Saved err====>', err?.message);
  });

};
