Back in the day, when the development scene was just starting to take off, developers’ main focus revolved around backend development. They were more concerned with building the behind-the-scenes functionality of applications, handling data storage, and managing server operations. However, with the introduction of JavaScript, front-end development became a thing, opening doors to new opportunities for developers to explore and develop new front-end frameworks. That's when Vue.js, Angular, and React emerged as the major players in this field.

Vue.js has several distinctive capabilities and characteristics that set it apart from other frameworks, and that’s exactly why we have chosen it as our main tech stack. First, it has a relatively shallow learning curve that makes it more accessible for developers of varying levels of expertise. It also keeps things structured and requires less complex architectural planning. So while using Vue.js, we had a leaner code experience and implemented our projects more simply and effectively.

Throughout our Vue.js journey and numerous intensive hiring rounds, we've discovered that there are certain technical skills every VueJs developer should have to tackle complex challenges, optimize performance, and deliver exceptional user experiences. In this article, we will shed light on these must-have tech skills and delve deeper into the essential aspects we think every Vue.js developer should satisfy. So let’s get into it.

The Essential Technical Skills Any VueJs Developer Should Have

In-depth knowledge of Javascript

Having a strong understanding of JavaScript is undeniably essential for Vue.js developers. It acts as the backbone that supports and enables building any Vue app. Being familiar with modern JavaScript features such as ES6+ syntax can help developers write more concise and efficient code. Besides, proficiency in asynchronous programming, promises, and callbacks will allow them to handle data fetching and manipulation more effectively within Vue.js apps.

Understanding Event Loop

A comprehensive understanding of event loop allows developers to grasp the asynchronous nature of Vue.js and efficiently handle operations like data fetching, API calls, and other non-blocking tasks. Moreover, when developers use Event Loop effectively, they can make more informed decisions to improve the overall application flow. They can prioritize tasks, implement techniques like debouncing or throttling, and even incorporate lazy loading for enhanced resource management.

Comprehending Vue Data Flow

A Vue.js developer must comprehend the flow of data within Vue components and understand concepts like one-way data binding and two-way data binding. This knowledge helps them manage the state and ensure data consistency throughout the application.

Global State Management

Global state management is another important skill for any Vue js developer to have, especially when working with complicated projects. Pinia libraries, for example, play a significant part when it comes to rapidly handling state interactions across various components. Pinia proficiency enables developers to organize and manage application-level data effectively, providing data integrity and simplified communication between components. It also provides a centralized store for state data and makes it more accessible and managed across the app. This simplifies development and improves overall application performance.

Choosing and Implementing Packages

An experienced Vue.js developer should also be pretty slick when it comes to using packages. In fact, it’s the best way to save time, avoid reinventing the wheel and focus on building unique features specific to the application. 

Some packages are thoroughly tested, reliable, and maintained by community members and may introduce new problems and bugs into the application. The art of choosing the correct packages to reuse and make them part of your Vue App is crucial for a good VueJs Developer. This might include checking the specific package’s popularity and reputation, maintenance and updates, documentation, community support, as well as performance.

Bug Handling

Another skill that should not be overlooked is bug handling. It is critical to handle bugs in a fast and efficient way in order to maintain the application's stability and performance. A professional developer is able to find, isolate, and resolve errors rapidly using various debugging tools and methods. They can also quickly track the execution flow, examine code, and identify the core cause of issues.

Rendering Methods

Vue.js supports a variety of rendering techniques, including templates, render functions, and JSX. Experienced Vue developers usually understands the distinction between these methods and knows when to employ each one depending on the demands of the project. Templates are a declarative method for basic components; on the other hand, render functions and JSX allow greater flexibility and control over advanced rendering logic. So understanding the rendering methodologies can help developers to create more dynamic user interfaces that are compatible with their project requirements.

Component Libraries And Customization

Using component libraries is another noticeable skill that any Vue js developer should have in their toolkit. Component libraries are essential tools since they allow to speed up development by using pre-built components. In fact, developers can build feature-rich apps more quickly by employing these libraries. 

However, just using off-the-shelf components may not always fit the project's unique design and functionality requirements. This is where the art of customization comes into play. Skilled Vuejs developers know how to tailor these components to match the project's specific needs, maintaining a consistent and personalized look and feel.

Overall, the combination of using component libraries and customization increases productivity and encourages a consistent user interface in the entire app.

Bundlers

Having a good understanding of bundlers, especially Webpack and Vite, since most of the applications come with either of those by default. 

Bundlers speed up the construction process by organizing assets like stylesheets and JavaScript scripts. They allow for code splitting, lazy loading, and other speed enhancements, leading to quicker load times and better application performance. Developers who are proficient in bundlers can create highly effective Vue.js apps that accommodate customers with different network conditions and devices.

Understanding Vue 3 and Composition API

A comprehensive understanding of Vue 3, as well as the Composition API, is something that's also worth noting while talking about the essential VueJs developer skillset. When compared to Vue 2, Vue 3 offers significant speed improvements and additional functionality. By structuring logic into reusable and composable functions, developers can build more scalable and maintainable apps by embracing the Composition API. As a result, an adequate understanding of Vue 3's improvements enables developers to keep up-to-date with Vue.js development in general while making use of the most recent tools and approaches.
