Advanced React Engineering for African Web Apps

Course outline and learning expectations

This is a tutor-led course. The outline shows what your tutor will cover; teaching materials and examinations are provided directly to enrolled students.

What you will learn

• Design advanced type-safe component APIs
• Select scalable state and data ownership patterns
• Measure and improve rendering performance with React profiling tools
• Apply code splitting, Suspense and non-blocking transitions
• Build resilient cached and real-time data workflows
• Create unit, integration, contract and end-to-end test coverage
• Develop accessible reusable design-system components
• Apply frontend security and dependency-risk controls
• Automate quality checks, builds and production deployments
