Puppeteer Sample Function

This is a sample working Node.js function that's designed to check the availability of the coveted LEGO UCS AT-AT product on the official website using Puppeteer and Chromium. It performs synthetic monitoring by simulating a visit to the product's page and checks the product's availability based on Schema.org data. It then takes a screenshot and uploads to storage for later viewing pleasure.

Prerequisites

• An Appwrite server setup and running.
• A project created in Appwrite with this function added.

Setup Instructions

Step 1: Add the Function to Appwrite

Create a new function in your Appwrite console. Choose the Node.js runtime.

Step 2: Configure Environment Variable

In the function settings in the Appwrite console, add an environment variable:

• Key: PUPPETEER_EXECUTABLE_PATH
• Value: /usr/bin/chromium-browser

This variable instructs Puppeteer to use the Chromium browser installed on the server.

Step 3: Modify Build Settings

In the function's Configuration > Build Settings, add the following command:

apk update && apk fetch chromium nss freetype harfbuzz ca-certificates ttf-freefont && npm i
