TFI Notifier is a simple Node application that scrapes fund data from the inPZU website, summarises it, and sends a daily report. It helps you better track your investments and lets you know if the indexes are falling.
The application is hosted on the Vercel platform as a serverless function and is triggered every day by a CRON job.
Normally, this kind of application would probably just call a backend API to get the required data, but unfortunately, in this case, it was not possible. To bypass API security, the notifier is using the UPDATE: Thanks to a bit of reverse engineering, a reliable way of getting data from the API has been found. In case of any issues in the future, scrapping logic might be reverted. After processing the gathered data, it is sent to the end-user's email via the Resend service.puppeteer-core package to run the chromium instance and scrape the data out of it.
