Scrap all users from Getform to file

This code performs a login, then get all users page by page before storing them in a local file.

const USERNAME="XXX@gmail.com";
const { chromium } = require('playwright');

//const browser = await chromium.launch();
const browser = await chromium.launch({
    headless: false,
    args: ['--window-size=1280,720'],

const page = await browser.newPage();

// login
await page.goto('https://app.getform.io/login');
await page.locator('//*[@id="__layout"]/div/div/form/div[2]/input').fill(USERNAME);
await page.locator('//*[@id="__layout"]/div/div/form/div[3]/input').fill(PASSWORD);
await page.locator('//*[@id="__layout"]/div/div/form/div[4]/button').click();
await sleep2(5000); // waiting ajax query//await page.waitFor(2000);
// go to form
await page.goto("https://app.getform.io/forms/18848");
await sleep2(3000); // waiting ajax query
// get nbr of pages
const footer = await page.$('//*[@id="formScroll"]/div/div/div/div/div[2]/table/div/div/div');
const nbrPages = await footer.evaluate(element => element.children.length);

let allEmails = [];

// load page and get data in table
for (let i = 1; i <= nbrPages; i++) {
    // click on page number
    await page.locator('//*[@id="formScroll"]/div/div/div/div/div[2]/table/div/div/div/a['+i+']').click();
    await sleep2(2000);

    // get data
    const table = await page.$('//*[@id="formScroll"]/div/div/div/div/div[2]/table/div/tbody');
    const emails = await table.evaluate(element => {
        const results = [];
        const array = Array.from(element.children).forEach(td => {
            const email = td.children[1].innerText;
            const submitDate = td.children[3].innerText;
            results.push({email, submitDate})
        return results;
    allEmails = [].concat(allEmails, emails);

// write to file
_fs.writeFileSync('/Users/alagrede/Desktop/users.json', JSON.stringify(allEmails));
//await page.screenshot({ path: '/Users/alagrede/example.png' });
await browser.close();

Read file and remove duplicate

Since Getform doesn't remove duplicate users, we deduplicate the results before displaying them.

function uniqByKeepFirst(a, key) {
    let seen = new Set();
    return a.filter(item => {
        let k = key(item);
        return seen.has(k) ? false : seen.add(k);

const data = JSON.parse(_fs.readFileSync('/Users/alagrede/Desktop/users.json', 'utf8'));
printJSON(uniqByKeepFirst(data, it => it.email).length);
