How to build modern Websites in 2020?

It’s 2020 and you want to learn how to create beautiful and modern websites in 2020? This Article will serve as a guide on what you should be looking into, in order to learn to build fast and beautiful websites. We’ll also mention some keyword for technologies with potential, which you can look into.

What is a Website in 2020?

A question that simple shouldn’t be asked in 2020, right? But the lines between Apps, Websites and Software is fading. Here is a good example: certain websites you visit on the phone, you can ‘add to homescreen’. This adds an icon of the website and makes it available even when you offline. (Here is good starting point if you want to learn more about this technology: Progressive Web Apps).

So what is it now? An App or a website? How can you access a website that is offline?

For the sake of simplicity we’ll say that everything is accessed via a browser, is a website. (Except for PDF files, Video files, etc.)

What was Webdesign?

The header is in past tense. Webdesign is loosing it’s value in some sense. The rise of many JavaScript Frameworks made it easy for everyone to create good looking and fast websites. This eliminates the need to hire a web designer to sketch your site from scratch.

Certain plugins go even a step further and give you finished and multi-functional User Interface Elements (for example a Button). You can read more on such frameworks here: Top 3 UI Frameworks.

So, where you start?

If you are starting your developer journey in 2020, you should feel blessed. You’ll receive advanced programming language and tons and tons of tutorials and cheap (but not always good) courses. Following lines assume that you want to know how to become a Frontend developer.

We’ll also assume that you don’t want to become a Frontend developer just for the sake of becoming of Frontend developer. The motivation behind this is mainly to earn money. Then comes fun and enjoyment. We do not distinguish whether you make money via a wage or freelance work.

In the end it all comes down to fulfilling the demand (for in Frontend development) with your supply of this skill.

Web Dev Basics

Every Website on the these two most basic technologies: HTML5 and CSS.

HTML5 equals to Hyper Text Markup Language 5. It’s the standard markup language for virtually every Website. HTML elements are the most basic elements of an HTML page.

CSS equals to Cascading Style Sheets. CSS takes the UI Elements that were created by HTML and adds some style to them – making our website beautiful and modern.

Modern Websites for Beginners

With the goal of making money and having fun as a newcomer to Frontend Development in mind, i introduce to you a very popular and easy to learn JavaScript Framework: Vue.js 2. There are many JS Frameworks that exist along Vue.js. The reason why Vue.js is so popular among Beginners, is that it is easy to learn. And while it’s easy to learn, it doesn’t compromise the important characteristics like scaling, performance, tests, automation, and so on. In short: it’s just perfect.

How to learn it? Well, some people prefer skimming through the docs and learn via trial&error. Others prefer a more focused and directed learning with Courses.

VueJS Practice – #4 Vuex Store

VueJS Practice – #4 Vuex Store

Here we go again, another VueJS Practice. This time we’ll discuss a very important part of every VueJS Application – the Central Data Store or Vuex Store. Vuex is a VueJS Plugin and extends your Application with centrally available Data and Methods.

Another VueJS Tutorail and Practice by German IT Academy.

Problem / Task

We want to create a Part that is centrally available in our Application: A Shopping Cart. Generate three products in the Vuex Store as states. Create a ProductList.vue View and a ShoppingCart.vue Component. The ProductList.vue should display the products stored in vuex – include a button “Add to Cart”. “Add to Cart” should add the selected Product to a centrally available list, so that the cart list can be access from any other Component. In that view, import ShoppingCart.vue, which should display all Items in the Cart.

Hint

  • For the products: use an Array or Object in Vuex.
  • Displaying multiple UI elements can be done with v-for directive.
  • Centrally available list is nothing else than a list of centrally avaiable products.
  • In order to follow the best practices, consider using
    • Vuex Getters to retrieve data
    • Vuex Actions to modify Vuex States from the outside (e.g. VueComponent)

Solution

As always, let’s jump right into the code.

<template>
  <div class="ShoppingCart">
    <h3>Shopping Cart</h3>
      <p v-for="(item, key) in cart" :key="key">
        {{ products[item].name }}
      </p>
      <hr>
  </div>
</template>

<script>
export default {
  name: 'ShoppingCart',
  computed: {
    products: {
      get() {
        return this.$store.getters['allProducts']
      }
    },
    cart: {
      get() {
        return this.$store.getters['getCartItems']
      }
    }
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
h3 {
  margin: 40px 0 0;
}
li {
  display: inline-block;
  margin: 0 10px;
}
a {
  color: #42b983;
}
</style>
<template>
  <div class="home">
    <img alt="Vue logo" width="300" src="https://i0.wp.com/code.git-academy.com/wp-content/uploads/2019/10/400dpiLogo.jpg?zoom=1.100000023841858&fit=2077%2C1175&ssl=1">
    <hr>
    <ShoppingCart/>
    <ul>
      <li v-for="product in products" :key="product.id">
        <h1> {{product.name}}</h1>
        <h3> {{product.price}} $</h3>
        <button @click="addToCart(product.id)">Add to Cart</button>
      </li>
    </ul>
  </div>
</template>

<script>
// @ is an alias to /src
import ShoppingCart from '@/components/ShoppingCart.vue'

export default {
  name: 'home',
  components: {
    ShoppingCart
  },
  methods:{
    addToCart(id) {
      this.$store.dispatch('addToCart', id)
    }
  },
  computed: {
    products: {
      get() {
        return this.$store.getters['allProducts']
      }
    }
  }
}
</script>

<style scoped>
li { 
  list-style-type: none;
  margin-bottom: 100px;
}
button {
  background-color: blue;
  color: white;
  font-size: 20px;
  border-radius: 25px;
  border: 1px solid black ;
}
</style>
import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default new Vuex.Store({
  state: {
    products: {
      0: {
        id: 0,
        name: 'VueJS T-Shirt black',
        price: 39
      },
      1: {
        id: 1,
        name: 'VueJS T-Shirt white',
        price: 39
      },
      2: {
        id: 2,
        name: 'VueJS T-Shirt blue',
        price: 39
      }
    },
    cart: []
  },
  getters: {
    allProducts(state) {
      return state.products
    },
    getCartItems(state) {
      return state.cart
    }
  },
  mutations: {
    pushCart(state, payload){
      state.cart.push(payload)
    }
  },
  actions: {
    addToCart(context, payload) {
      context.commit('pushCart', payload)
    }
  }
})

Below you can see the visual result of the above code. If you are interested in more VueJS Practice, examples and tutorials, feel free to enroll in our VueJS Course and get certified by German IT Academy.

VueJS Practice

In the store.js we specify out getters. Our products and cart are just lists in the vuex states object. When we press on “Add to Cart”, we initiate a Vuex Action called “Add to Cart” with “this.$store.dispatch(‘addToCart’, id)“. The ShoppingCart.vue simply iterates over the Vuex State Cart and prints out the items.

It’d be better to outsource the v-for loop in ProductList.vue into another Vue-Component ProductItem.vue. ProductList.vue would import ProductItem.vue as a child, and pass a product id. Then, ProductItem.vue could display the product by selecting it via id.
