I have been trying to find a way to possible connect a front end to this javascript code to be able to fill out some contracts more efficiently

const {PDFDocument} = require('pdf-lib');
const { readFile, writeFile} = require('fs/promises');

const fs = require('fs')

async function createPDF(input, output) {
    try{
        const pdfDoc = await PDFDocument.load(await readFile(input));

        //Modify PDF, fill out
        const fieldNames = pdfDoc
            .getForm()
            .getFields()
            .map((f) => f.getName());
        console.log({ fieldNames });

        const form = pdfDoc.getForm();

        form.getTextField('Given Name Text Box').setText('Test');

        const pdfBytes = await pdfDoc.save();

        await writeFile(output, pdfBytes);
        console.log('PDF CREATED')
    } catch (err) {
        console.log(err);
    }
}

createPDF('OoPdfFormExample.pdf', 'output.pdf')
