Full-Stack Web Application Development (MERN Stack)
Build end-to-end web applications connecting React frontend to Node.js backend with database persistence.
About This Assessment
Full-stack JavaScript developers are in exceptionally high demand with companies seeking unified skillsets to reduce team size and accelerate development. With 80,000+ full-stack professionals in the US and massive applicant pools for entry-to-mid level roles, this assessment validates end-to-end development capability—from UI components through API logic to database operations—filtering out candidates who only know isolated pieces.
What Candidates Will Do
Build a React frontend with forms and data display components, implement client-side routing
Create a Node.js/Express backend with REST API endpoints that handle frontend requests
Connect backend to MongoDB, implement database models/schemas and CRUD operations
Integrate frontend and backend: make API calls from React, handle responses, display data from database in UI
Implement basic authentication flow (register/login) with session or token management
Automated Grading
Verify full application stack runs: React dev server and Express API both start, frontend makes successful HTTP requests to backend, backend queries MongoDB and returns data, user can create/read/update records through the UI with data persisting to database, authentication blocks access to protected routes, proper error handling throughout the stack, CORS configured correctly
Environment
Ubuntu 22.04 VM with Node.js 20+, npm, MongoDB 7, create-react-app or Vite template, Express.js, Git. May need to run frontend (port 3000) and backend (port 5000) simultaneously.
