This Node.js function is designed to check the availability of the LEGO AT-AT product on the official LEGO 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.

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

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

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.

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
