Better Component Composition in VueJS

In VueJS there are few ways to compose components and reuse logic. In this article, I would like to demonstrate a way to boost composition in Vuejs (2.* and 3.*).

I really like the recent proposals regarding the Composition API, but I think that can be part of a broader view.

Below, you can find a component implementing a general use case (a simple data fetching from a remote endpoint and displaying the different transitions and data), though most of the logic is always duplicated along with the template, data, and other variables when the same logic is applied to other places or components.

<template>
<div>
    <div v-if="loading"> Loading... </div>
    <div v-if="error"> An Error occured, please try again</div>
    <div v-if="hasData"> {{ data }} </div>
</div>
</template>

</template>

<script>
    export default {
        data() {
            return {
                loading: false,
                error: false,
                data: {}
            }
        },
        methods: {
            fetchData() {
                this.loading = true;
                setTimeout(() => {
                    this.data = { text: 'example' };
                    this.loading = false;
                }, 4000);
            }
        },
        computed: {
            hasData() {
                return this.data && !!this.data.text;
            }
        },
        mounted() {
            this.fetchData();
        }
    }
</script>

How do we refactor this component and improve it? Let’s go step-by-step and make this component more readable and reusable.

How to Publish a Vuejs Component on NPM

In this post, I will explain you now how to publish your own VueJs component on npm with a minify and ES5 build.

Composite Design Pattern in Java

Here I am with another useful design pattern for you — the composite design pattern. I will try to point out the key features to remember while implementing the composite pattern for you.

Composite Design Pattern

The composite pattern is meant to “compose objects into a tree structure to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions of objects uniformly”

• Composite design patterns describe groups of objects that can be treated in the same way as a single instance of the same object type.
• The composite pattern allows us to “compose” objects into tree structures to represent part-whole hierarchies.
• In addition, the composite patterns also allow our clients to treat individual objects and compositions in the same way.
• Composite patterns allow us to have a tree structure for each node that performs a task.
• In object-oriented programming, a composite is an object designed as a composition of one-or-more similar objects, all exhibiting similar functionality. This is known as a “has-a” relationship between objects.

Vue is an amazing framework for 2020. Why?

An amazing conference regarding the Vue framework was held in the US in the first week of March 2020 for two fantastic days. Some spectacular presentations were given during that time regarding the design, feature, and application tools of the framework. One of the most eye gazing things was that combining vue.js development services, professionals, and others as there were more than 900 attendees at the event. The brand new composition API for the Vue3 was the talk of the town.

All this leads to the conclusion that Vue might have an opportunity to be the most amazing for the year 2020. While the first quarter has been significantly better for it, let’s look at some of the characteristics which make the Vue an amazing framework for 2020.

Friendly learning curve & ease of integration

Ask any Vue.js developer and they will tell you that how working with this framework is very relaxing and even if you are a beginner, fundamental knowledge of HTML, CSS, and Javascript is good enough to build a simple application.

Do you know more than 75% of Vue.js development services just prefer it because of its ease of integration? This means you can hire Vue.js developers to build the application right from the scratch or can get an existing application accommodated to your requirements.

Although the inbuilt guide and documentation of the Vue framework make it sufficient for you to start coding.

This might interest you to know that Vue.js is for progressive web applications which also support libraries like Vue router, Vuex, Vue Test Utils, Vue-dev tools, Vue CLI for performing various functions.

It may seem a bit exaggerated but the truth is whether its loader, renderer, component caching or asset preload, etc every tool, every component in this framework performs very efficiently.

Top reasons why Vue.js is becoming the most trending JS-based framework

As noted above how Vue.js development services state that creating an application with Vue is very simple. So now we are going to look briefly into some of the top reasons why Vue.js development companies favor it from the stack of all JS-based frameworks.

Adaptable development environment: Very beneficial to the large scale projects, now and again Vue.js has proved that it adjusts with the components of other applications and develops it in remarkably less time compared to other JS-frameworks. Have you wondered why people are using it comprehensively?

Supported Libraries: Vue.js provides support libraries for any possible difficulties a developer might face. As Vue Router is for routing, Vuex for state management, Vue Test Utils for unit testing, Vue-dev tools for debugging, and Vue CLI for plugin management. And the best part here is this all inbuilt are accessible 24/7. Vue.js developer can rectify or alter the coding with the help of these support libraries.

Great Performance: For developing mobile apps, this framework tends to perform well in comparison to other frameworks. The speed of the loading page is significantly better than any other Javascript. Whether it’s a website or any other application, reliability and great performance is always the best advantage of the framework.

Community meets: Live events or meetings are organized regularly so that the Vue.js developer can get the regular updates of the features and benefits of the framework. This community is growing bigger day by day and is managed by Evan You, the developer of Vue.js framework himself.
