@kulkarniankita9
@kulkarniankita9 Use cases • Monitor your credit score - using
biometrics • Food delivery app • Reporting
@kulkarniankita9
@kulkarniankita9 1. Project structure
@kulkarniankita9 Directory structure index.js src auth index.js actions/epic/reducer/selector common components
button primaryButton/secondaryButton/tertiaryButton utils constants store storybook locale Modules
@kulkarniankita9 Challenges • A lot of shared context made it
difficult to share code Vertical slicing modules eg: auth, biometrics
@kulkarniankita9 2. React context and state management
@kulkarniankita9 Project
@kulkarniankita9 Is Context a state management solution?
@kulkarniankita9 Does Context replace redux?
@kulkarniankita9 Do you need redux?
@kulkarniankita9 We couldn’t get rid of state management library
@kulkarniankita9 Common context examples ✨ • Auth context • Orders
context
@kulkarniankita9 Challenges • Context was used as a state management
solution When the app was small, this worked fine but not when it grew Look into a state management solution Examples: Redux, Apollo cache

@kulkarniankita9 Without GQL
@kulkarniankita9 With GQL
@kulkarniankita9 With GQL
@kulkarniankita9 Challenges • We were missing data transformation using Apollo
hooks Added validation on top of this to check for null values
@kulkarniankita9 5. Performance
@kulkarniankita9 Container and presentational components
@kulkarniankita9 • Container and Presentational components • Use memoization •
Use pure functions • Code splitting
@kulkarniankita9 6. Documentation and on-boarding
@kulkarniankita9 Docs! • Add a task to add some documentation
to every Jira ticket • Practice what you preach
@kulkarniankita9 7. Accessibility
@kulkarniankita9 React a11y • https://github.com/dequelabs/react-axe • Lighthouse
@kulkarniankita9 Lighthouse
@kulkarniankita9 8. With hooks ⚓
@kulkarniankita9 Common hooks ✨ • Translation hook • Accessibility hook
for reducing motion • Responsive breakpoints
@kulkarniankita9 9. Testing
@kulkarniankita9 What gave us more confidence?
@kulkarniankita9 Testing • Unit testing • React component testing: react-testing-library
• API data transformation layer testing • Integration testing • Automation testing
@kulkarniankita9 10. Forms are hard, use a library
@kulkarniankita9
@kulkarniankita9 Libraries used • Formik • redux-form
@kulkarniankita9 Example
@kulkarniankita9 Design pattern • Multi-step sign-up process • JSON form
builder
