The world wide web consists of over 1.7 billion websites and over 2.76 billion pages. To access these websites and pages, 5 billion Internet users rely on user interfaces (UI). A web UI enables users to interact with websites and web applications via a browser; thus, clearly, websites and UIs are closely intertwined, and you can’t have one without the other.
Vue.js also allows developers to take advantage of built-in libraries for client-side routing and state management. Whenever required, they also have the freedom to select different routing/state management libraries based on their application requirements.
Vue.js comes with a CLI (Command Line Interface) to streamline development and simplify app creation by means of:
The CLI provides numerous project configurations that can be used as-is, plus end-to-end testing libraries, easy-to-use routing systems, and Server-Side Rendering (SSR) to present fully-rendered web pages to search engine crawlers. But apart from preset configurations, you can also create your own for TypeScript, linting, and testing.
The Vue.js CLI includes a built-in development server so you can run your app locally and test it prior to deployment without configuring a server yourself. Plus, the various build tools work smoothly with sensible defaults, so you don’t have to waste time or effort on configurations and can focus on writing app code instead. If required, you can easily change the configuration of each tool without the need for ejecting.
The Vue.js CLI, combined with other frontend development tools, makes it easy to set up Vue.js. Some functionality is included by default, but you can also build code with a DRY (Don’t Repeat Yourself) logic and structure. Plus, it comes with several plugins that can be included when creating a new project, added into it later, or grouped into reusable presets.
Components play a crucial role in developing web apps with Vue.js.
They break up a large application into smaller and distinct building blocks. Developers can easily create these blocks and manage them separately. They can add and render components asynchronously or on-demand with Vue’s “lazy loading” feature, which is a great way to reduce the file size and HTTP request-response time.
It’s also easy to transfer data between components since Vue.js simplifies communication between component hierarchies. These smaller blocks make it easier to write, test, and optimise application code. The template, logic, and styles are inherently coupled inside each component. Such collocation makes components more cohesive and easier to maintain.
With the Vue.js framework, you don’t have to place your application template, logic, and styling code into separate files. Instead, you can group all these elements into a single global file ending with a .vue extension. As a result, your team can take advantage of build-time tools like Webpack or Browserify to add more sophisticated components to the web application.
These build tools automate the creation of executable applications from source code by compiling, linking, and packaging the code into an executable form. Developers can automate a number of day-to-day tasks such as downloading dependencies, compiling source code into binary code and then packaging it, running tests, and even deploying the application to production.
Another reason for Vue’s popularity is that it provides a rich, incrementally-adoptable ecosystem that can seamlessly scale between a library and a full-featured framework. Vue.js is also a highly approachable framework with intuitive APIs and world-class documentation.
Vue.js is also highly performant with built-in reactivity. Its rendering system is compiler-optimised, so it rarely requires manual optimisation. Real-time functionality is also a breeze with Vue.js, so you can easily apply simple directives in your applications.
One of the most frequently-used capabilities in Vue.js is the ability to create computed properties. With such properties, you can easily modify, manipulate, and display data in a highly readable format while removing excess logic in templates.
Vue.js has a good history of disclosing and patching new security vulnerabilities - which are fortunately seemingly pretty rare. However, more recently, cross-site scripting (XSS) and regular expression denial of service (ReDoS) vulnerabilities have been discovered, so being informed about how they manifest and possessing the skills to close these vulnerabilities once their fixes have been issued is paramount.
One way to steer clear of these vulnerabilities and ensure that the application remains secure is to always use the latest version of Vue and its official companion libraries. Vue also suggests several ways to maintain application security:
Some other best practices to protect your Vue applications include:

Vue.js is a user-friendly, feature-rich, progressive, and powerful front-end development framework for web UIs. However, the security of Vue.js applications is only as good as the security awareness of those who create them. In other words, developers who don’t code securely will end up creating insecure Vue applications, with the resulting vulnerabilities in these applications opening up the organisation mainly to cross-site scripting (XSS) attacks.
To avoid calamity from an ill-conceived Vue.js app, it’s vital to train your team on secure coding practices in Vue.js. But old-fashioned training programmes that are chock-full of boring videos and outdated examples are not enough to bring developers up-to-speed on today’s security challenges. To successfully overcome these challenges and create fully secure Vue.js UIs, developers need hands-on training that allows them to apply their learnings in the real world.
SecureFlag provides a 100% hands-on virtual development environment for Vue security awareness training. Developers learn how to identify and remediate threats through hands-on exercises for better learning retention and tangible results.
