Puppeteer: multiple user requests to the same Chromium instance - amazon-web-services

Question

To hopefully save on system resources I want to run user requests through the same Chromium version in Puppeteer.
If a user submits a form on my site which calls Puppeteer, and Chromium is already running, how can I use the same Chromium instance up to a maximum of 4 tabs?
If there are more than 4 tabs open in the Chromium instance then I want to launch a new Chromium instance.
How can I achieve this? Would I need to store the browserWSEndpoint of the Chromium instance to a file and then retrieve it every time a new user submits a request? (This would be using browserWSEndpoint with puppeteer.connect()).
If I have to do it this way, lets say there are 2 Chromium browsers active. The first most recent browser has the maximum four open tabs, so I could not use this browser. I would then check the next browserWSEndpoint and, if there are less than 4 open tabs, create a new page; and if not, launch a new browser.
Does that sound OK?

You can use Lambda which would save you cost , make sure to avoid the 30 seconds timeout of lambda if you are going to be using API Gateway.

NodeJS
const chromium = require('chrome-aws-lambda');
exports.handler = async (event, context) => {
let result = null;
let browser = null;
try {
browser = await chromium.puppeteer.launch({
args: chromium.args,
defaultViewport: chromium.defaultViewport,
executablePath: await chromium.executablePath,
headless: chromium.headless,
});
let page = await browser.newPage();
await page.goto(event.url || 'https://example.com');
result = await page.title();
} catch (error) {
return context.fail(error);
} finally {
if (browser !== null) {
await browser.close();
}
}
return context.succeed(result);
};
