Creating a Puppeteer microservice to deploy to Google Cloud Functions

Puppeteer is a high-level API for controlling headless Chrome, ideal for automating web interactions when direct URL navigation or public APIs are unavailable. The article provides a detailed guide on setting up a Node.js project to perform an automated search on GitHub using Puppeteer, illustrating how to focus on input fields, type keywords, and navigate search results. It explains the importance of selecting correct DOM elements and handling visibility issues due to layout changes. The process includes creating a service function in Puppeteer, wrapping it with an Express server to handle keyword searches as route parameters, and deploying it on Google Cloud Functions to create a serverless microservice. The guide emphasizes the need for proper cloud function settings, such as memory allocation and public accessibility, while highlighting the potential security considerations for production environments.
