Perform Puppeteer actions in Laravel controller using JavaScript code

Question

I'm using Puppeteer to launch the browser from a laravel controller, but I don't know how to run JavaScript code from the controller

My function is as follows:

$script = <<<SCRIPT
    const puppeteer = require('puppeteer');
    (async () => {
        const browser = await puppeteer.launch({headless: false});
        const page = await browser.newPage();
        await page.goto('http://my-url.com');
        const button = await page.$('button#button');
        await button.evaluate( button => button.click() );
        await page.waitForTimeout(5000);
        ...
        await browser.close();
    })();
    SCRIPT;
$process = new Process(['node', '-e', $script]);
$process->run();
$output = $process->getOutput();

When I try to run just this part of the code in node shell:

const puppeteer = require('puppeteer');
(async () => {
    const browser = await puppeteer.launch({headless: false});
    const page = await browser.newPage();
    await page.goto('http://my-url.com');
    const button = await page.$('button#button');
    await button.evaluate( button => button.click() );
    await page.waitForTimeout(5000);
    ...
    await browser.close();
})();

It works fine and I can see a browser opened. When I try to run the entire function it doesn't work. So I think the way I'm running the JS code in the controller is wrong.

I created a new js file for the JavaScript code script.js

// script.js

const puppeteer = require('puppeteer');
(async () => {
    const browser = await puppeteer.launch({headless: false});     
    const page = await browser.newPage();
    await page.goto('http://my-url.com');
    const button = await page.$('button#button');
    await button.evaluate( button => button.click() );
    await page.waitForTimeout(5000);
    ...
    await browser.close();
})();

And in the controller I've made the changes:

$process = new Process(['path/to/node', 'path/to/script.js]);
$process->run();
if(!$process->isSuccessful()) {
  throw new ProcessFailedException($process);
}
$output = $process->getOutput();
$errors = $process->getErrorOutput();

This worked for me
