Docxtemplater - RangeError: Invalid string length

Question

I'm turning a very large txt file(~40MB) into docx but it seems that the string is too large for Node.js to handle.
Is there any fix for it? Or another solution?
My code:

import fs from 'fs';
import path from 'path';
import Docxtemplater from 'docxtemplater';
import Pizzip from 'pizzip';

const txt = path.parse(process.argv[2]);

const text = fs.readFileSync(process.argv[2]).toString().split('\n');

const docx = new Docxtemplater()
    .loadZip(new Pizzip(fs.readFileSync('./template.docx')))
    .setData({text: text})
    .render();
fs.writeFileSync(`./down/${txt.name}.docx`,
    docx.getZip().generate({type: 'nodebuffer'}));

<ProjectDir>\node_modules\docxtemplater\js\join-uncorrupt.js:90
    return full + part;
                ^

Answer 1

This is something that should now be fixed in docxtemplater 3.27.1, which I've just published.

npm install docxtemplater@^3.27

should therefore fix your issue.
