React, Svelte and Vue.js are the best frameworks for front-end development. Let’s talk about what they are, how to use them, their key elements and why they stand out from other frameworks.
Uses of React
- Creating web and mobile apps: While React.js is commonly used to build web apps, the React Native framework is used to create mobile apps. Hence, you can use React for developing both web and mobile apps like Netflix, Facebook, Reddit, etc.
- You can also use React to build dynamic websites like to-do sites, blogs and other sites that need frequent updates.
Key elements of React
- React comprises multiple reusable components, which have their own logic and controls. These assist you in maintaining code when working on large-scale projects.
- One-way data binding gives you better control throughout an application because the data flows in only one direction.
- The virtual DOM facilitates excellent performance in React by re-rendering the entire UI whenever there are modifications to a web app.
Pros of React
- The virtual DOM in React improves the performance of an application.
- A React web app has various reusable components with logic and controls.
- In React, you can create Dynamic Web Applications by combining HTML strings with fewer lines of code.
- It’s easily testable.
Cons of React
- There's always an evolution or update to React, and some developers feel it's an additional task to regularly learn these updates.
- Updates to React are often under-documented.
- React covers only front-end development. You'd have to add other tools to complete development on the back end of a mobile application.
Uses of Svelte
- Applications built with Svelte have lesser bundle sizes, perfect for devices with slow network connections and limited processing power. Less code means fewer KBs to download.
- Svelte ensures that user interactions are fast and responsive, perfect for creating highly interactive pages or complex visualizations. You can use Svelte for building dynamic front-end interactive user interfaces, fast web applications and fast and lean static web apps. The New York Times, Absolute Web and Cashfree are a few websites that were built with Svelte.
Key elements of Svelte
- It uses no Virtual DOM, as it's a proper compiler.
- In Svelte, an application is composed of multiple components.
- Svelte is reactive.
Pros of Svelte
- Svelte is the framework that best meets the API of the web. It only adheres to the standard and only builds on what exists. It doesn't invent anything new, unlike React (which built JSX).
- Svelte is 30% faster than other frameworks.
- It’s a "disappearing framework," giving it freedom from client-side dependencies.
- Svelte enforces single-file components to help organize your projects.
- It offers out-of-the-box animations and transitions like Sapper.
- It’s used to create server-side rendered apps.
- Svelte Native can be used to create mobile apps.
- Svelte is easy to use; you can do a lot with less code.
- Svelte is a compiler, giving it the ability to do many things that non-compiler frameworks can't do.
Cons of Svelte
- There are routing issues attached to using Svelte. You can't build a one-page web application without a standard router, and there aren't many offered in Svelte.
- Svelte lacks significant support, unlike Angular or Vue, which are supported by Google, or React, which is supported by Facebook.
Uses of Vue.js
- Vue.js is primarily used to build single-page applications.
- Vue.js is also useful for prototyping. With the proper data binding, it can handle a lot of animations, interactive elements and graphics. Once you’ve learned your front end and installed the Vue CLI, you can easily build clickable prototypes.
Key elements of Vue.js
- Vue.js inherited two-way data-binding from Angular. Two-way data binding connects model data updates and UI. Bound components contain data that you can update regularly. Two-way data binding makes it easier to update related components and track updates.
- Out-of-the-box tools & libraries. Vue.js has an excellent package of tools for all basic programming needs offered on its main page:
- Vue’s official CLI - The Command Line Interface (CLI) is used for the development and installation of the Vue.js framework’s core libraries and third-party plugins.
- Development Tools - For debugging applications built with Vue.js.
- Vue Loader - The official loader for web packs.
- Vue Router - For routing and mapping components.
- VuePress - Initially created for writing technical documentation, this is a small, compact and powerful headless CMS.
Pros of Vue.js
- Vue.js is easy to integrate into other projects. Simply include the CDN in your HTML and create specific Vue.js components or elements for your website.
- It's a fast and lightweight framework.
- It uses virtual DOM, which enhances app performance.
- Vue.js has excellent community support on Stack Overflow.
- It gives you a standard for code organization and expectations. Its code is easy to read and understand, you can store all the components in separate files, and each component is just a single file.
Cons of Vue.js
- The two-way data-binding primarily keeps components in sync. However, it introduces the issue of reactivity complexity into the system.
- You can encounter issues in Vue.js when working on relatively large projects because of its lack of support for large-scale projects.
- Its flexibility and room for plenty of options can breed confusion among developers.
- As Vue.js was largely built and popularized in China, much of its content and discussions are in Chinese, creating a language barrier.
