Vue.js is a JavaScript-based framework mainly used for
building web interfaces and one-page applications. As more flexible and
less-opinionated alternative to Angular, Vue has become a popular choice among
big companies, including Xiaomi, Alibaba, and Gitlab. Vue.js also provides a
Virtual DOM, the virtualisation technique that has revolutionized the rendering
process, plus its two-way data binding makes it a preferable solution for
creating apps with real-time updates. The framework offers code reusability and
superb unit testing as well as extensive documentation that makes Vue.js easy
to learn and understand even for beginners.The benefits of VueVue.js has been gaining in popularity since its launch nine years ago. Why? As it offers the following benefits:
Simplicity:
Vue has a short learning curve, making it a great technology for beginners.Lightweight:
Significantly smaller in size than competitor Angular’s projects.Exhaustive
documentation: Even developers with zero to little knowledge about
JavaScript can start to easily build apps with Vue.The best of
React and Angular: Vue took the best from React and Angular and left out
the disadvantages of both technologies.Component-based
architecture: Provides code reusability and lucidness as well as enables
fruitful unit testing.Extended
integration capabilities: Vue offers a much wider spectrum of integration
capabilities compared to both Angular and React.Rich ecosystem:
Vue comes with a variety of tools and technologies that simplify and streamline
software development.In this article, we have selected five best practices that
every Vue developer should know to write code faster, better, and more
efficiently. 5 best practices of Vue.JS#1: Learn how to use Key Attributes A key attribute is crucial for data manipulation as it
allows your system to remain predictable. Especially when you use the v-for
directive, without the key attribute, Vue will begin to render in DOM in the
order of efficiency - even if it goes against your logic. However, if you
assign a key reference to each v-for element, you will be able to predict the
way the Vue DOM will proceed with the code. #2: Use kebab-case as your naming conventionTo preserve code consistency and readability, it is
recommended to use kebab-case for components, where you use dashes between
words when they are identifiers. Alternatively, you can use PascalCase but
remember to stay consistent. PascalCase (naming with internal caps) might be
more beneficial as it is supported by many IDE auto-complete functions.
Luckily, using kebab-case in Vue is easy for JavaScript developers as the
framework automatically converts between the Vue’s kebab-case and JS’s
camelCase. #3: Include prop validationsThis practice helps you have a clear and easy-to-follow
structure and avoid misunderstandings and miscommunications. Especially if you
are working on a large project, make sure to specify formats, types, and other parameters for a prop.
Your teammates or employees will appreciate clear and concise definitions about
component usage. To streamline your business processes and workflow, always be
transparent about components and add prop validations. #4: Be consistent when naming componentsVue is a framework with comprehensive documentation,
including materials about base components such as HTML elements, third-party UI
components, and others. Base components should be named using prefixes like
base, v, and app but the best practice is about consistency. It is completely
up to you and your team which title to choose for your components but providing
consistency is crucial for a successful project of any size. Additionally, it is important to learn about single instance
components, (components that are used once per page). They should be defined
with the prefix “the” to stand out from other components. Single instance
components refer to headers, sidebars, and footers. #5: Stick with basic JavaScript expressionsThis best practice addresses the creation of templates.
Templates should entail only basic JS expressions to be readable,
understandable, and reusable. If you try to add too much functionality into one
template, it will seem complex and cluttered. The point of templates is to be
universal and applicable to a variety of situations. Overcomplicating the
functionality of a template goes against the applicability. Despite the simplicity that Vue offers, there are a handful
of great tricks and tips that will streamline development efforts, no matter
your skill level. It is easy to master, yet Vue provides access to a variety of
advanced features so as your experience grows, so can your projects. If you would like to learn more about this JavaScript
