This project is a client-side tool that fetches a GitHub user’s entire contribution history and renders it as a single, continuous timeline chart. It operates entirely in the browser as a single-page application, using the HTML5 Canvas API to draw a pixel-level heatmap where color intensity reflects contribution frequency across every day from account creation to the present.
The tool retrieves data through authenticated requests to the GitHub API, then aggregates daily counts into a date-range timeline without requiring any server-side processing. Its output serves as a comprehensive visual dashboard of a developer’s open-source activity, suitable for portfolio displays or profile enhancement. The application is self-contained, with no page reloads during data fetching or rendering.
