Covid19 Tracker is an open-source Next.js dashboard that shows real-time coronavirus distribution worldwide through an interactive map and per-country, per-continent analysis.
What is Covid19 Tracker?
Covid19 Tracker (viewable at trackcovid19.vercel.app) is a web application built with Next.js that tracks the latest coronavirus distribution around the world. It consumes a Covid-19 data API and outputs an interactive distribution map, country-specific statistics, continent-specific statistics, a most-affected-countries list, and global trends for the past 365 days. The project was bootstrapped with create-next-app, is written in TypeScript, and styled with Tailwind CSS.
Key Features
- Interactive distribution map — Renders Covid-19 case data on a map using react-leaflet.
- Country and continent analysis — Users can drill down to see statistics for a specific country or whole continent.
- Most affected countries list — Ranks countries by Covid-19 impact on a leaderboard-style list.
- 365-day worldwide record — Displays a historical curve of global cases over the past year.
- Current worldwide data — Shows the latest global total cases on the dashboard.
- Dark mode — The UI includes a dark theme, as noted in the repository's dark-mode topic.
- SSR and responsive design — Next.js server-side rendering is enabled, and the layout adapts to mobile and desktop.
Who is it for?
- Data journalists — need country- and continent-level stats to cite in articles about the pandemic.
- Public health teams — can monitor the 365-day trend to identify new waves or improvements.
- Developers — can use this as a starter template for building a chart- and map-heavy dashboard with Next.js and Tailwind.
- General visitors — can browse the live app to check current global Covid numbers.
Use cases
- Journalists covering Covid-19: pull the most-affected-countries list and continent analysis for a story.
- Health communicators: embed the map or share links to country-specific pages during briefings.
- Developers learning Next.js: study how SSR, Redux, and react-leaflet are integrated in a real project.
How does Covid19 Tracker work?
The project is a standard create-next-app setup. To run it locally, clone the repository, run npm install, then npm run dev, and open http://localhost:3000. The app fetches Covid-19 data from an API on the server (Next.js SSR) and passes it to the front-end components for rendering.
