Playwright - Nstbrowser API

Whether you are looking to get started, or already have an established codebase, Browserless aims to make the transition as easy as possible. At a high-level, you'll need to do the following:

Generate API Key

Go over Nstbrowser Client Dash's API menu or go to: https://app.nstbrowser.io/app/api

Install playwright

If you haven't picked a library yet we highly recommend Playwright. It's an active open-source project with tons of contributors. Developed by Microsoft, Playwright supports multiple browsers (Chromium, Firefox, and WebKit) and multiple programming languages (Nodejs, Python, .NET, and Java), making it one of the most versatile and high-quality browser automation tools out there.

Nodejs

Python

pnpm

yarn

npm

Setup your app use Browserless

Once we have Browserless account setup, we can simply "connect" to it in our application instead of launching local Chrome.

That's it! Now you don't have to worry about bundling Chrome or it's dependencies in production and can continue to develop your application.

Below is a sample cURL call that will use your new service to ensure it's all working:
