Our Process
Project Setup & Architecture
Establishing development environment and project structure
- →Initialize Next.js project with TypeScript configuration
- →Set up folder structure following best practices
- →Configure ESLint, Prettier, and code quality tools
- →Implement Git workflow and branching strategy
- →Set up environment variables and configuration management
Component Development
Building reusable UI components based on design specifications
- →Create component library from design system
- →Implement responsive layouts using Tailwind CSS
- →Build stateful components with React hooks
- →Ensure proper prop typing with TypeScript
- →Write unit tests for component functionality
State Management
Implementing efficient data flow and state handling
- →Set up global state management (Redux/Context API)
- →Implement data fetching with React Query or SWR
- →Handle form state and validation
- →Manage authentication and user session state
- →Optimize re-renders and component performance
API Integration
Connecting frontend with backend services
- →Create API client with proper error handling
- →Implement data fetching and caching strategies
- →Handle loading states and error boundaries
- →Set up authentication tokens and headers
- →Test API integrations thoroughly
Performance Optimization
Ensuring fast load times and smooth user experience
- →Implement code splitting and lazy loading
- →Optimize images and assets (Next.js Image component)
- →Minimize bundle size and remove unused code
- →Implement caching strategies for static content
- →Monitor Core Web Vitals and performance metrics
Testing & Deployment
Quality assurance and production release
- →Write unit tests with Jest and React Testing Library
- →Perform cross-browser and device testing
- →Ensure accessibility compliance (WCAG 2.1)
- →Set up CI/CD pipeline for automated deployments
- →Monitor production performance and error tracking
At least two team members have reviewed and approved the code changes
Code follows team coding standards, style guide, and best practices
ESLint/Prettier passes with zero errors and warnings
Complex logic is well-documented with clear comments and JSDoc
All console.log statements and debug code removed from production
Minimum 80% code coverage with meaningful unit tests
All integration tests pass successfully in CI/CD pipeline
Feature tested manually across different scenarios and edge cases
Verified functionality in Chrome, Firefox, Safari, and Edge
Tested on mobile devices (iOS/Android) and tablets
Existing features still work correctly after changes
