CodeSynth is a Git-Hub–integrated code-quality dashboard that lets developers instantly lint any public repository without cloning it locally. Authenticate with GitHub, pick a repository, and receive a grouped summary of ESLint issues, per-file details, and quick-fix suggestions. CodeSynth was built to give engineering students and professionals a friction-free way to gauge code health and learn best practices.
- GitHub OAuth – one-click sign-in with GitHub.
- Repository Analyzer – fetches repo contents through the GitHub API and performs in-memory ESLint analysis.
- Persistent Dashboard – save, revisit, or delete analyzed repositories (full CRUD).
- File Tree & Preview – navigate directories, view file contents, and see inline lint messages.
- JWT-secured API – stateless communication between React front-end and Express back-end.
- Responsive UI – Tailwind CSS + shadcn/ui ensure a cohesive theme on any screen size.
- Deployed on Heroku – live demo available 24 × 7.
