Price Protection Notifier

Golang lambda function that runs daily, checks a list of product pages, and notifies you if the price you set it to watch for is reached.

Built with Golang, MongoDB, AWS Lambda

Usage

Upload the main.zip to AWS Lambda and set it on a daily trigger (You can use Cloudwatch events for this)

I use it with the ESP Mailgun, but it should be usable with any email provider of your choice.

Necessary environment variables

MONGO_URL=mongodb://...
MONGO_DB=...
MONGO_COLLECTION=...

Interacting with the products database

The following commands let you interact with the database:
