1. WAYS TO COMPOSE IN REACT JAKE TRENT
2. 1. WRAP CHILDREN 2. SPECIAL CHILDREN 3. VALUES AS PROPS 4. COMPONENTS AS PROPS 5. OVERRIDE METHODS 6. HIGHER-ORDER COMPONENTS
3. Wrap Children <Parent> <Child /> <Child /> </Parent> - Hierarchy - Style
4. Special Children const SpecialChild = props => <div>{props.specialness}</div> const Parent = props => <div> {React.Children.map(props.children, child => child.type === SpecialChild ? React.cloneElement(child, { specialness: 'somethingFromParent' }) : child )} </div> - Nice APIs - Data sharing
5. Values as Props const GiveMeValues = props => <div>{props.orGiveMe}</div> <GiveMeValues orGiveMe="death" /> - Dynamic values
6. Components as Props const Title = _ => <h1>Composition!</h1> const SubTitle = _ => <div>Over Inheritance -- Literally</ div> const Header = props => <header> {props.title} {props.subtitle} </header> <Header title={<Title />} subtitle={<SubTitle />} /> - Dynamic UI - Component encapsulation
7. Override Methods const defaultHandleClick = _ => alert('common clicked') const Common = props => <button onClick={props.handleClick ? props.handleClick : defaultHandleClick}>Click me</button> const overrideHandleClick = _ => alert('specific click') const Specific = _ => <Common handleClick={overrideHandleClick} /> - Dynamic functionality - Reuse common components
8. Higher-order components const OriginalComponent = props => <div style={props.style}>Style me</div> const HigherOrder = newStyle => originalComponent => props => originalComponent({ ...props, style: { ...props.style, ...newStyle } }) const AlwaysRed = HigherOrder({ color: 'red' }) (OriginalComponent) - Share common functionality
