Twitter-Clone

The twitter clone is my ninth project of Scrimba Front-End course, in this course I build the duplication of twitter from scratch and structure the code to finish the layout design.

How I start the project?

Learn how to set the textarea for user to input their replies, and render the replies.
Insert the icons from the "Font Awesome CDN" website.
Increase & Decrease the number of the "likes" and "tweets" icons.
Change the color of icons when clicking.
Render the replies by getting their UUID, and improving the UX.

1. - Create a new tweet

Designing a twitter clone social media website requires following some rules and taking into consideration about each scrum tutorial. This project can be split into several small parts.

1.1 - Add the textarea

Take control of the data from Textarea when clicking button, then make sure the size of textarea fixed.

ℹ️ [TEXTAREA] GET to know more about the element. → W3School
resize for textarea element.

textarea{
    border: none;
    padding: 10px;
    margin: 0 0 20px 0;
    height: 60px;
    width: 100%;
    font-size: 20px;
    line-height: 30px;
    resize: none;   //keeps textarea the same size
}

1.2 - For each method to iterate the array

Look through how to use .forEach() → .forEach()

const characters = [
    {
        title: 'Ninja',
        emoji: '🥷',
        powers: ['agility', 'jsstealth', 'aggression'],
    },
    {
        title: 'Sorcerer',
        emoji: '🧙',
        powers: ['magic', 'invisibility', 'necromancy'],
    },
    { 
        title: 'Ogre',
        emoji: '👹',
        powers: ['power', 'stamina', 'shapeshifting'],
    },  
    { 
        title: 'Unicorn',
        emoji: '🦄',
        powers: [ 'flight', 'power', 'purity'],
    }
]

characters.forEach(function(character){   //The purpose of using forEach is to make the code easy to read.
    console.log(character)
//The result shows below.
//{title: "Ninja", emoji: "🥷", powers: ["agility", "stealth", "aggression"]}
//{title: "Sorcerer", emoji: "🧙", powers: ["magic", "invisibility", "necromancy"]}
//{title: "Ogre", emoji: "👹", powers: ["power", "stamina", "shapeshifting"]}
//{title: "Unicorn", emoji: "🦄", powers: ["flight", "power", "purity"]}

2. - Control the icons

2.1 - CDN

Explaination why should we use CDN. → AWS The icon examples which we can get from here. → FONT-AWESOME-CDN

⚠️ The first step to use the CDN, copy code and paste the link into then paste “class” details into the section

<section class="icons-bar">
     <i class="fa-solid fa-house"></i>
     <i class="fa-solid fa-location-dot"></i>  //Get icon resource class name //Have to understand the concept of the data attribute.
     <i class="fa-regular fa-envelope"></i>
     <i class="fa-regular fa-calendar-days"></i>   //This is the example of how to use the data-attribute in the class.
</section>

⚠️ The defination of the Data Attribute: deta-unique-name="your data"

2.2 - Get value of data-attribute

document.addEventListener('click', function(e) {
		if (e.target.dataset.share){
    			console.log(e.target.dataset.share)   //output is image-1, review the code above，after clicking: output shows "image"
		}     //if return T then the data-share inside data element   //The output is DOMStringMap {share: "image-1"}
})

⬆ back to top

2.3 - Find the tweet obj and increase the like number

import { tweetsData } from './data.js'
const tweetInput = document.getElementById('tweet-input')
const tweetBtn = document.getElementById('tweet-btn')

tweetBtn.addEventListener('click', function(){
    console.log(tweetInput.value)
})

document.addEventListener('click', function(e){
    if(e.target.dataset.like){
       handleLikeClick(e.target.dataset.like) 
    }
})

function handleLikeClick(tweetId){
    const targetTweetObj = tweetsData.filter(function(tweet){
        return tweet.uuid === tweetId  //if the tweet id is the same of the loop id，then return true
    })[0]  //The output is object, not array
    targetTweetObj.likes++  //increase the like number when clicking
    console.log(tweetsData)
}

⬆ back to top

2.4 - Flip the boolean to control the like and dislike

//Make sure to listen to the button
document.addEventListener('click', function(e){
    if(e.target.dataset.like){
       handleLikeClick(e.target.dataset.like) 
    }

function handleLikeClick(tweetId){ 
    const targetTweetObj = tweetsData.filter(function(tweet){
        return tweet.uuid === tweetId
    })[0]

    if (targetTweetObj.isLiked){
        targetTweetObj.likes--
    }
    else{
        targetTweetObj.likes++ 
    }
    targetTweetObj.isLiked = !targetTweetObj.isLiked   //The goal is to flip the boolean.
    render()
}

2.5 - Conditionally Render CSS

const galleryContainer = document.getElementById('gallery-container')

let isLiked = false
let isShared = false

document.addEventListener('click', function(e){
    if(e.target.dataset.heart){
        isLiked = !isLiked  //flip the boolean short-hand
        render()
    }
    else if(e.target.dataset.share){
        isShared = !isShared  //flip the boolean short-hand
        render()
    }
})

function render(){ 
    
    let heartClass = ''  //initialize the variable
    let shareClass = ''
    
    if(isLiked){
        heartClass = 'liked'  //if "isLiked" is true then set up the Class to "liked"
    }
    
    if(isShared){
        shareClass = 'shared'   
    }
       
    let imageHtml = `
    		<div id="image-1" class="img-container">
			<img src="dino2.jpeg" alt="Man in front of dinosaur">
			<div class="social-icons-container">
				<i class="fa-solid fa-heart ${heartClass}" data-heart="image-1"></i>
				<i class="fa-solid fa-share ${shareClass}" data-share="image-1"></i>
			</div>
    `
    galleryContainer.innerHTML = imageHtml
}

render()

<section class="gallery-container" id="gallery-container">
</section>

.liked{
    color: #f80000; /* red */
}

.shared{
    color: limegreen; 
}

3. - Replies setup

3.1 - Get the UUID of replies

function getFeedHtml(){
    let feedHtml = ``
    
    tweetsData.forEach(function(tweet){  //loop through the object
        
        let likeIconClass = ''
        
        if (tweet.isLiked){
            likeIconClass = 'liked'
        }
        
        let retweetIconClass = ''
        
        if (tweet.isRetweeted){
            retweetIconClass = 'retweeted'
        }
        
        if(tweet.replies.length > 0){
            console.log(tweet.uuid)   //check the length of the tweet if there is any replies then output its UUID
        }
}

⬆ back to top

3.2 - Provide each reply unique UUID

import { v4 as uuidv4 } from 'https://jspm.dev/uuid'; //import the UUID JS 
  
const cars = [
    {
    brand: 'Nissan',
    model: 'Leaf',
    price: 3000,
    uuid: '4fb2b6b7-c7ee-4c80-8de1-390e89f43d7f'
    }, 
    {
    brand: 'Toyota',
    model: 'Prius',
    price: 6000,
    uuid: '82a13f62-d239-46a2-a94f-020189338e1a'
    }, 
] 

cars.push({
    brand: 'Tesla',
    model: 'Model S',
    price: '🤦‍♂️',
    uuid: uuidv4()  //Input function
})

console.log(cars)

<html>
    <head>
        <link rel="stylesheet" href="index.css">
    </head>
    <body>
        <script src="index.js" type="module"></script>  //setting to module
    </body>
</html>

3.3 - Push the new tweet to the dataset

function handleTweetBtnClick(){
    tweetsData.unshift({   //tweet the post in the beginning of the object
        handle: `@Scrimba`,
        profilePic: `images/scrimbalogo.png`,
        likes: 0,
        retweets: 0,
        tweetText: tweetInput.value,
        replies: [],
        isLiked: false,
        isRetweeted: false,
        uuid: uuidv4()
    })
    render()    
}

⬆ back to top

3.4 - Improve the UX

function handleTweetBtnClick(){
    const tweetInput = document.getElementById('tweet-input')
    if(tweetInput.value){       //If the value in the textarea exists then push the data into the array.
        tweetsData.unshift({
            handle: `@Scrimba`,
            profilePic: `images/scrimbalogo.png`,
            likes: 0,
            retweets: 0,
            tweetText: tweetInput.value,
            replies: [],
            isLiked: false,
            isRetweeted: false,
            uuid: uuidv4()
        })
    render()
    tweetInput.value = ''
    }
}
