You need to set the executablePath which got from executablePath method of chromium (which comes from package ) const browser = await puppeteer.It can also be configured to use full (non-headless) Chrome or Chromium. You can find the compatible version on this support page npm install install Screenshot from Chromium support pageįor example, I've installed the second latest version as shown below npm install install Puppeteer Configurationīelow is the puppeteer configuration. One important point to note here is that you need to install compatible versions of these packages. We're going to use npm package for chromium along with puppeteer-core As we would like to use this in AWS Lambda, we need to find a trimmed version that takes less space and is suitable for serverless environments. The maximum deployment size of Lambda is 250 MB. The size of the latest chromium would be around ~282 MB in Linux. You need to install chrome/chromium separately. The difference between puppeteer and puppeteer-core is that when you install puppeteer package, it will install the latest version of chromium by default whereas when you install puppeteer-core package, it will just install puppeteer without any chrome installation. Puppeteer is available in 2 packages - puppeteer and puppeteer-core. Puppeteer packagesīefore discussing how to use puppeteer with AWS Lambda, we need to discuss how puppeteer works at a high level. You can learn more about AWS CDK from a beginner's guide here. AWS CDK supports many languages including TypeScript, Python, C#, Java, and others. It's an open-source software development framework that lets you define cloud infrastructure. As you may know, Puppeteer is a Node.js library that provides a high-level API to control Chrome/Chromium.
In this tutorial, we're going to learn about how to use puppeteer with AWS Lambda.
