Components

• If
• Then
• Else
• For
• Switch

If

Working

• Based on the condition the children are rendered.

• If the condition is true then the childeren will render otherwise it will return null.

• For one children

  • If condition is true then children will be rendered.
  • If condition is false then null gets returned.

• For multiple children

  • If conndition is true then the first children will rendered.
  • Otherwise the all of the children will be rendered excluding the first children.

Example

import { If } from 'classic-react-components'

export default function YourComponent() {
   return (
      <div>
         {/* Passing only one children and a condition prop */}
         <If codition={true}>
            <h1>it will render.</h1>
         </If>

         {/* Passing more than one children and a truthy condition prop */}
         <If codition={false}>
            <h1>it will not render</h1>
            <h2>it will render. As condition it falsy</h2>
         </If>

         {/* Passing more than one children and a falsy condition prop */}
         <If codition={falsy}>
            <h1>it will not render</h1>
            <h2>it will render. As condition it falsy.</h2>
            <h2>it will also render</h2>
         </If>
      </div>
   )
}

Usage with Suspense

import { If, Then, Else } from 'classic-react-components'
import { lazy } from 'react'

const YourLazyComponent = lazy(() => import('./YourLazyComponent'))

export default function YourComponent() {
   return (
      <div>
         {/* Passing two children, condition and suspense props */}
         <If codition={false} suspense>
            {/* This component will only download when the condition evaluates to true.
             Here condition is falsy, it will not be downloaded. */}
            <Then>
               <YourLazyComponent />
            </Then>
            <Else>
               <h2>this is will render</h2>
            </Else>
         </If>
      </div>
   )
}

Then

Working

• It should be used in-conjunction with If commponent.
• It renders the passed children.

Example

import { If, Then } from 'classic-react-components'

export default function YourComponent() {
   return (
      <div>
         <If codition={true}>
            <Then>
               <h1>this will render.</h1>
            </Then>
         </If>
      </div>
   )
}

Else

Working

• It should be used in-conjunction with If commponent.
• It renders the passed children.

Example

import { If, Then, Else } from 'classic-react-components'

export default function YourComponent() {
   return (
      <div>
         <If codition={2 + 2 == 4}>
            <Then>
               <h1>this will render.</h1>
            </Then>
            <Else>
               <h1>this will not render.</h1>
            </Else>
         </If>
      </div>
   )
}

For

Working

• Replacement for Array.map().
• Used to iterate over an array of items and renders the JSX based on the provided child function.

Example

import { For } from 'classic-react-components'
import CardComponent from './CardComponent'

export default function YourComponent() {
   const Data = [
      { id: 1, course: 'Javascript' },
      { id: 2, course: 'React' },
   ]
   return (
      <div>
         <For data={Data}>
            {(item, index) => {
               return <CardComponent key={item.id}>{item.course}</CardComponent>
            }}
         </For>
      </div>
   )
}

Switch

Working

• Renders the children of particular matched case for given prop item(switch value).
• If no case matches for given prop item, the Default case will be rendered.

Note: The order of Default Case does not matter.

Example

import { Switch } from 'classic-react-components'
import CardComponent from './CardComponent'

export default function YourComponent({ item }: { item: 'coding' | 'sleep' }) {
   return (
      <div>
         <Switch item={item}>
            {({ Case, Default }) => {
               return (
                  <>
                     <Case value='coding'>
                        <div>coing-case</div>
                     </Case>
                     <Case value='sleep'>
                        <div>sleep-case</div>
                     </Case>
                     <Default>
                        <div>this is default case</div>
                     </Default>
                  </>
               )
            }}
         </Switch>
      </div>
   )
}
