I am new to javascript and I'm trying to make a PDF file from a firebase function using pdfkit. Below is my function code.

const pdfkit = require('pdfkit');

const fs = require('fs');



exports.PDFTest = functions.https.onRequest((req, res) => {



var doc = new pdfkit();



var loremIpsum = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam in...';  



doc.y = 320;

doc.fillColor('black')

doc.text(loremIpsum, {

paragraphGap: 10,

indent: 20,

align: 'justify',

columns: 2

});  



doc.pipe( res.status(200) )



});

The function starts but then a timeout error happens.
Is this the best way of going about creating a pdf file in firebase?
I have some html that I want made into a pdf file.

Just working on this too, for saving the PDF in the storage it works like this

const myPdfFile = admin.storage().bucket().file('/test/Arbeitsvertrag.pdf');

const doc = new pdfkit();

const stream = doc.pipe(myPdfFile.createWriteStream());

doc.fontSize(25).text('Test 4 PDF!', 100, 100);

doc.end();



return res.status(200).send();

Guess you should wait until the stream is closed and listen for Errors and Things, but this is the first working example I was able to make, now working on how to get a Image from the storage into the PDF.
