Uptime Monitor
A Full Stack application that monitors websites, stores history and sends email alerts.
- React
- Node.js
- MongoDB
- Cron
- Nodemailer
Overview
An observability solution for registering websites, tracking availability and understanding recent behavior through logs and charts.
The challenge
Run recurring checks without manual action, retain each website’s history and alert quickly whenever a service stops responding.
The solution
A Node.js job powered by node-cron checks websites every two minutes. Results are stored in MongoDB, alerts use Nodemailer, and the React frontend presents uptime, logs and Recharts visualizations.
Architecture
- Responsive React and Vite frontend
- Node.js and Express REST backend
- Recurring jobs with node-cron
- MongoDB with Mongoose and Nodemailer alerts
Key deliverables
- Create and remove monitored websites
