The gist: build an app that allows a user to enter a URL for the app to check periodically to ensure it responds with a successful 2XX response; if not, email the user.
You know what stinks? When your websites or web apps go down. So let's build a web app that tells us when that happens. This project is pretty straightforward and has aspects different from other content-manage-y apps.
I'd probably call this project Watchpup! 🐶
- Authentication (sign up, log in, log out)
- Add websites to check with a name and URL
- Check the website shared for a 200 response every 30 mins (can be less or more frequent)
- Log successful and unsuccessful checks so it's clear whether or not a check ran and how it went
- If the website is down, email the user the site is down
- Periodic job running
- HTTP requests
- Configurable frequency for checking
