Common Vue.js Mistakes and How to Avoid Them
Have you ever wondered why corporate behemoths are trending towards Javascript frameworks especially to create a strong online presence? Well, escaping the gravitational pull of the veteran technology is certainly next to impossible, especially in the current modern web development era. Several Javascript frameworks such as Reach, Angular, Node, and Vue seem to have gained a lot of attention from tech enthusiasts and this continues to grow with each passing day.
Now as we all know Javascript is full-fledged on its own featuring a wide range of tools, libraries, languages and frameworks making the life of a software engineer pretty easy and seamless. Since we don’t have much time I won’t get into the details of every Javascript framework but will focus on just one, Vue. In the following post, you will learn why Vue is one of the leading Javascript frameworks, some of the common Vue.js mistakes made by the developers, and how to avoid them.
Vue’s Overview
For starters, Vue is one of the leading open-source, progressive, lightweight Javascript frameworks developed with the purpose of creating exceptional UIs. Any developer who has mastered HTML, CSS and Javascript can get started with the Vue framework. According to the StackOverflow Survey held in the year 2022, Vue.js stands at the 6th position. So this is definitely one of the core reasons for why you should be considering Vue for 2023. Well, of course, this is not it, there are several other compelling reasons to be taken into account such as the framework itself is pretty progressive and leverages Model-View-Model-View design. With an objective of developing web interfaces and one-page applications, Vue is considered one of the core aspects of conducting any modern web application development project. With Vue, it is possible to create
Compact and Portable Applications
Intelligent performant applications
If you want an early market launch
Single-page applications from scratch
Above all, when you are willing to create responsive, user-driven frontends ensuring an unparalleled user experience, look no further than Vue. Some of its outstanding features include:
Simple to use
Lightweight
No steep learning curve
Easily adaptable
High-end Community
Declarative Rendering
Two-way Binding
Speed and Performance
Now I can simply go on and on when it comes to showcasing the advantages and benefits of any Javascript framework. However, we also have to cover one of the most crucial aspects of any web development scenario, i.e. common mistakes made by developers across the globe and how to avoid them. You see, even after you go through the post, I cannot guarantee that you won’t make any kind of mistakes. You see they are inevitable and these trials and errors lead to massive innovation but what I am pretty sure about is that you won’t repeat these common ones especially while working with Vue.js.
Some of the Common Vue.js Mistakes to Consider
#1 Adding Template Compiler
One of the common mistakes found across the globe among Vue.js developers is that they keep on adding template compilers. And once you do that, you will find the inline template for your component returns a blank page. And there is also no point in defining templates through the render function or as a single file component because there is no issue here. So what could be the reason here? Well, maybe because Vue comprises different builds. And the default one doesn’t feature a template compiler.
Now even if you know JSX for React, there is no point because template compilers tend to work in a pretty same way as they work for React. So what happens here is that the template strings are being replaced with the help of the function to develop a virtual DOM node.
Now I am sure you must be wondering how this is possible, and why the same issue never arises in single-file components. Well, the answer is pretty simple here: they use vue-loader and vueify tools.
So what should be done is, to make sure the developer specifies the right build and then import. Also, try creating an alias in the bundler configuration.
#2 Making all Data Reactive
The next common Vue.js development mistake to avoid is making all the data reactive. There are times when with a click of a button more and more data gets pushed into the user’s array and what happens next is that the rendered list automatically increases in size.
So does this mean there should be reactivity for each user item? Certainly not! And you know that Vue is reactive by default. So the framework does successfully lookout for significant changes in each user item by incorporating setters and getters. So you are bound to find a sudden increase in rendering time and memory consumption.
So what to do? Well, how about you use the freeze method of an Object? After all, this can make the array immutable ensuring that the Vue engine avoids adding setters and getters to the array items.
#3 Conjunction
Last but certainly not least, a mistake made by Vue.js developers across the globe is using the Vue framework in conjunction with other DOM manipulation tool kits featuring jQuery and several others. Well, most young and experienced developers tend to choose jQuery to manipulate a DOM widget or use Vue. However, keep this in mind, never use both at the same time. The wrapper component acts as a link between Vue components and internal DOM elements. It also ensures Vue to interact seamlessly with other components and manipulate other elements successfully.
In a Nutshell
And we are done for now! These are some of the most common yet crucial mistakes to keep in mind while conducting any Vue.js development project. I hope you did find the post worth reading. If so, do share among your peers and help us in tooting our horns loudly.
