Node JS Puppeteer headful Browser doesnt launch

Question

I'm playing around with puppeteer to learn a bit about automation in the browser. I wanted to open the chromium browser visable so not in headless. I set the launch option to false, but it's still not opening Chromium.

I tried to use no sandbox args, i did even deflag the --disable-extensions in the args, but nothing helped..

There are no errors in the terminal, it just doesn't launch.

Here is my code:

const puppeteer = require ("puppeteer");

async () => {
  const browser = await puppeteer.launch({ headless: false });
  const page = browser.newPage();
  await page.goto("https://google.de");

  await browser.close();
};

Any idea why chromium is not opening? Also there are no logs about errors...

Problem

You are not calling the function, you are just defining it via async () => { ... }. This is why you are not getting any errors, as the function is not executed. In addition, as the other answer already said, you are missing an await.

Solution

Your code should look like this:

(async () => {
  const browser = await puppeteer.launch({ headless: false });
  const page = await browser.newPage(); // missing await
  await page.goto("https://google.de");

  await browser.close();
})(); // Here, we actually call the function
