The how and why of flexible React components THE HOW
AND WHY OF FLEXIBLE REACT COMPONENTS
Hi! I’m Jenn. Senior Frontend Engineer, ClassPass @gurlcode
@gurlcode
flexible @gurlcode

<BlockComponent className=“block block-md block—orange” message={message} withTooltip={false} withModal modalProps={modalProps} userId={userId} userName={userName}
withDot={false} experimentRunning experimentId={experimentId} colorChange={false} showMessageOnLoad onModalClose={() => {}} hasRoundedCorners withAnalytics analyticsProps={analyticsProps} /> BEWARE THE APROPSCALYPSE <BlockComponent className=“block block—md block—orange” withTooltip={false} withDot={false} withModal modalProps={modalProps} onModalClose={onModalClose} onMouseOver={onMouseOver} withExperiment experimentId={experimentId} userName={userName} userId={userId} analyticsProps={analyticsProps} roundedCorners /> @gurlcode
@gurlcode
@gurlcode
You have another reservation at this time. @gurlcode
Is the user logged in? State of subscription? Join State
of class? Reactivate Reserve Cancel Disabled Join yes no cancelled subscribed unsubscribed available unavailable reserved @gurlcode
None
@gurlcode
reusable !== flexible @gurlcode
Flexibility is about more than reusability. It’s about the ability
understand and augment. @gurlcode
@gurlcode
@gurlcode
<ScheduleCta type={?} /> @gurlcode
@gurlcode
@gurlcode
@gurlcode
@gurlcode
Keep business logic out of your components. @gurlcode
@gurlcode
Centralized logic is easier to reason about @gurlcode
Test the component separate from the logic @gurlcode
@gurlcode
<ScheduleCta type={?} /> @gurlcode
@gurlcode
@gurlcode
@gurlcode

@gurlcode
<ScheduleCta type={?} /> @gurlcode
components[type] @gurlcode
components = { reserve: ReserveCta, join: JoinCta, cancel: CancelCta, disable:
DisableCta, reactivate: ReactivateCta } @gurlcode
const Component = components[type]; @gurlcode
const Component =`${left || right}Sidebar`; @gurlcode
const Component = props.isCard ? ( <Card> <Content /> </Card>
) : (<Content />); @gurlcode
@gurlcode
@gurlcode
@gurlcode
@gurlcode
@gurlcode
<ScheduleCta type={?} className=“” />
@gurlcode
Decreased prop complexity Use whatever logic we want Use individual
CTAs alone Add & remove CTAs with ease Use whatever logic we want Use individual CTAs alone Add & remove CTAs with ease @gurlcode
CTAs added and removed for A/B tests Removing Disable CTA
on some pages Classnames changed Messaging changed for ReserveCta Ask for specific CTA on specific page @gurlcode
Hmm… @gurlcode
Render Props* *children as a function @gurlcode
… so what if children were a function? @gurlcode
@gurlcode
? ? ? ? ? ? ? ? ? ?

@gurlcode
Render Props === state delegate children function === UI handler
@gurlcode

@gurlcode
you === flexible @gurlcode
@gurlcode
Know your traps. @gurlcode
Kill your darlings. @gurlcode
Start with the ideal API Let the API inform the
component design Decide what level of magic you want Business logic does not belong in components Render Props is awesome (use it!) Be flexible as an engineer (know your traps, kill your darlings) @gurlcode
