LAB | React Training

Introduction

The purpose of this exercise is to practice the core React concepts such as: creating components, passing data through props, working with state, rendering lists, and working with forms (controlled components).

To see the expected result for each iteration, refer to the solution example: React Training - solution.

• lastName: A string

• firstName: A string

• gender: A string, 'male' or 'female'

• height: A number

• birth: A date

	gender='female'
	height={172}
	birth={new Date("1988-05-11")}
	picture="https://randomuser.me/api/portraits/women/44.jpg"

/>

Expected Output:

---

Iteration 2 | Component: Greetings

Create a Greetings component with 2 props:

• lang: A string that can have values: "de", "en", "es" or "fr"

• children: A text

The component should display a greeting text in the chosen language.

Example:

<Greetings  lang="de">Ludwig</Greetings>

<Greetings  lang="fr">François</Greetings>

Expected Output:

---

Iteration 3 | Component: Random

Create a Random component with 2 props:

• min: A number

• max: A number

The component should display a random integer in the range between the min and the max number.

Example:

<Random  min={1}  max={6}/>

<Random  min={1}  max={100}/>

Expected Output:

---

Iteration 4 | Component: BoxColor

Create a BoxColor component that displays a rectangle with a background color based on props. For this, you will need to add inline styles (documentation).

The component should take 3 props:

• r: A number between 0 and 255 representing the amount of red

• g: A number between 0 and 255 representing the amount of green

• b: A number between 0 and 255 representing the amount of blue

Example:

<BoxColor  r={255}  g={0}  b={0}  />

<BoxColor  r={128}  g={255}  b={0}  />

Expected Output:

As a bonus, you can also display the hex values of the color (e.g., #ff0000 for red).

---

Iteration 5 | Component: CreditCard

Create a CreditCard component that displays a rectangle with the information coming from the props.

The component should take 8 props:

• type: A string that can be "Visa" or "Master Card"

• number: A string that is the number of the credit card. For security reasons, you should only display the 4 last digits 😉

• expirationMonth: A number that represents the month, between 1 and 12

• expirationYear: A number that represents the year

• bank: A string that represents the name of the bank

• owner: A string that represents the name of the owner

• bgColor: A string for the background color of the card

• color: A string for the text color of the card

Take your time to make the component look as close to the expected output as possible. You'll probably want to use flexbox.

Example:

<CreditCard
	type="Visa"
	number="0123456789018845"
	expirationMonth={3}
	expirationYear={2021}
	bank="BNP"
	owner="Maxence Bouret"
	bgColor="#11aa99"
	color="white"
/>

<CreditCard
	type="Master Card"
	number="0123456789010995"
	expirationMonth={3}
	expirationYear={2021}
	bank="N26"
	owner="Maxence Bouret"
	bgColor="#eeeeee"
	color="#222222"
/>

<CreditCard
	type="Visa"
	number="0123456789016984"
	expirationMonth={12}
	expirationYear={2019}
	bank="Name of the Bank"
	owner="Firstname Lastname"
	bgColor="#ddbb55"
	color="white"
/>

Expected Output:

---

Iteration 6 | Component: Rating

Create a Rating component that displays 5 stars. Depending on the value received, some stars should be empty (☆), and some should be filled (★).

The component should take 1 prop:

• children: A number between 0 and 5. The value can be a floating-point number. If the number received is 3.9, the component should display 4 stars.

Example:

<Rating>0</Rating>

<Rating>1.49</Rating>

<Rating>1.5</Rating>

<Rating>3</Rating>

<Rating>4</Rating>

<Rating>5</Rating>

Expected Output:

---

Iteration 7 | Component: DriverCard

Create a DriverCard component that displays a rectangle with content based on the received props.

The component should take 4 props:

• name: A string

• rating: A number between 0 and 5. The value can be a floating point number.

• img: A string

• car: An object with properties model and licensePlate.

Example

<DriverCard
	name="Travis Kalanick"
	rating={4.2}
	img="https://si.wsj.net/public/resources/images/BN-TY647_37gql_OR_20170621052140.jpg?width=620&height=428"
	car={{

	}}
/>

Expected Output:

---

Iteration 8 | State: LikeButton

Create a LikeButton component that displays a button with the initial text "0 Likes". With each click, the number of Likes should increase.

As a bonus, implement the background color change on each click. You can use the following array of colors: ['purple','blue','green','yellow','orange','red']

Example:

<LikeButton  />

Expected Output:

---

Iteration 9: State: ClickablePicture

Create a ClickablePicture component that displays a picture. On each click, the picture should toggle between the two images passed through the props.

Example:

<ClickablePicture

img='./assets/images/maxence.png'

imgClicked='./assets/images/maxence-glasses.png'

/>

Expected Output:

PS: If you want to use your picture instead, you can create it using this picture: http://www.stickpng.com/assets/images/584999937b7d4d76317f5ffd.png 😎

---

Iteration 10 | State: Dice

Create a Dice component that displays a picture with the random dice value (example: './assets/images/dice3.png').

Every time the user clicks on the component, it should:

• First, display an empty picture ('./assets/images/dice-empty.png')

• 1 second later, display a new random picture (example: './assets/images/dice6.png').

Example:

<Dice  />

Expected Output before the click:

Expected Output immediately after the click:

Expected Output 1 second after the click:

---

Iteration 11 | State: Carousel

Create a Carousel component that displays an image and two buttons (Left and Right), which change the picture on each click, respectively.

The component should take 1 prop:

• images: An array of strings. Each string should be an image URL.

Example:

<Carousel

images={[
'https://randomuser.me/api/portraits/women/1.jpg',
'https://randomuser.me/api/portraits/men/1.jpg',
'https://randomuser.me/api/portraits/women/2.jpg',
'https://randomuser.me/api/portraits/men/2.jpg'
]}

/>

Expected Output:

---

Iteration 12 | List and Keys | NumbersTable

Create a NumbersTable component that displays a list of numbers between 1 and the limit. Even numbers must be colored in red.

The component should take 1 prop:

• limit: A number.

Example:

<NumbersTable  limit={12}  />

Expected Output:

---

Iteration 13 | Lifting State Up - RGBColorPicker

Create 2 components:

• The RGBColorPicker component, that displays a square with an rgb color coming from the state.

The component should have the following state variables:

• rValue: A number between 0 and 255, representing the amount of red

• gValue: A number between 0 and 255, representing the amount of green

• bValue: A number between 0 and 255, representing the amount of blue

• The SingleColorPicker component should have an input field of type "number", and allow the user to select a number between 0 and 255.

The component should take 3 props:

• color: A string that is either "r", "g" or "b"

• value: A number between 0 and 255

• onChange: A method that is triggered when the input is changed

The RGBColorPicker should render 3 SingleColorPicker components and send the state values to them.

Example:

<SingleColorPicker
	color="r"
	value={rValue}
	onChange={ () => { /* ... */ } }
/>

  

<SingleColorPicker
	color="g"
	value={gValue}
	onChange={ () => { /* ... */ } }
/>

  

<SingleColorPicker
	color="b"
	value={bValue}
	onChange={ () => { /* ... */ } }
/>

Expected Output

Happy coding! ❤️
