The framework wars have made it hard to determine which one is the best as each has its advantages and disadvantages and is better suited for different types of applications. This has led to a discussion within the development community as to which framework is the best and which should be used for different types of projects. Ultimately, the decision comes down to the individual developers’ preferences and needs.
What is React?
React was designed with performance in mind. It is designed to be declarative and component-based, allowing developers to create reusable components that can be composed into larger UIs. It also makes use of the Virtual DOM to optimize rendering performance. Additionally, React employs the use of state management libraries such as Redux and MobX to manage application state in an efficient and scalable way.
What is Svelte?
Svelte has gained popularity since its inception due to its simple yet powerful approach to UI development. It is easy to learn and use, and it has excellent documentation. It is also incredibly lightweight, with no external dependencies.
Overall, Svelte is a great framework that offers an easy and efficient way to create user interfaces. It is a great choice for any project, whether you are just starting out or are an experienced developer.
We will introduce the points where the two frameworks will be compared against each other: Performance, Bundle Size, Community Support, and Maintenance.
While Reactjs is slower in comparison as it relies on the virtual DOM. React is more suitable for applications that don’t require as much data manipulation and don’t need to be updated as often.
Where do Svelte over-performance over Reactjs comes from?
Svelte cuts lots of corners in its compilation. It interprets its application code during build time. This means that its complies the application code during the compilation of the code and does use virtual stuff during in runtime.
In contrast to Svelte, Reactjs interpretes its code during the runtime of the code. During runtime, Reactjs keeps a snapshot/representation of the real DOM in what is called the virtual DOM (vDOM), this vDOM is what Reactjs uses to mirror what will eb appended to the real DOM.
Svelte produces smaller bundles than Reactjs. Svelte's bundle size is 1.6KB gzipped version while Reactjs bundled size is 42.2KB, this is due to its compile-time approach. Also, Reactjs tends to generate more code than Svelte as it needs to maintain the virtual DOM.
React, yet being lightweight is merely focused on the view layer only. You will need third-party if you are going past the view layer only. For state management, we will have to install redux and react-redux. For network requests and server communication, we will have to install any of the network libraries, e.g axios, got, etc. or we can just use fetch. For reactivity, we will have to install rxjs.
This is different in Svelte, because everything is in-built in Svelte, from state management to reactivity.
## Components Components in Reactjs and Svelte differs. In Reactjs, components are either classes or functions that are exported from .js, .ts, .jsx, and .tsx.
In Svelte, components are written in .svelte files and Svelte exports it, we don't have to do anything.
import FilterButton from "./FilterButton.svelte";
Our UI elements are written in the .svelte and Svelte does the magic behind the scene. In terms of styling, Svelte modularized their styling or we can say that Svelte scoped the styling in components. This means that the styling will be unique to the component, there will not be any conflicts in the styling. This just like in Nextjs(a SSR-version of Reactjs), we can either create global styling or unique styling for components.
## Community Support We will look into the community support of both frameworks to see who has stronger support and that may last for a very long time.
Without a doubt, Reactjs has a larger community and more resources for developers. There are tons upon tons of React blogs treating various features and advanced topics of Reactjs. Nowadays, you need only the internet to learn React. Also, Facebook has a devoted team of smart engineers supporting and maintaining Reactjs. Also, being open-source thousands of developers all over the world work towards supporting Reactjs.
On the other hand, Svelte has fewer resources and is relatively new. So, it has fewer people in its community yet, it is so because it is very new and people are adopting slowly.
Reactjs beats Svelte in maintenance because Facebook is at its helm, and they also have a dedicated team that works round the clock to maintain the framework. Reactjs has seen a lot of new and huge releases, making React the ideal framework for everybody to adopt. We have seen the releases of functional components, React Context, Hooks, etc.
Svelte has also a great maintenance team that works to keep Svelte highly performant and in contention with Reactjs.
When to use React and when to use Svelte?
React is a great choice for larger projects that require a lot of features. It has a strong community and lots of support, and is backed by Facebook, so you know it's reliable. It's also great for making complex user interfaces because it's easy to create reusable components with React. It also has a lot of features and tools built in, so it's a good choice for teams that need to build large applications quickly.
When it comes to choosing between React and Svelte, the best option is to assess the needs of your project. If performance and optimized code are important, then Svelte may be the better choice. On the other hand, if you need to create large and complex applications quickly, then React may be the better option. Additionally, if you want to create dynamic user interfaces, then Svelte is the better choice.
Ultimately, it depends on the needs of your project and the amount of time you have to develop it. React is a great choice for larger projects, while Svelte is better for smaller, more dynamic projects. It really all comes down to the specific needs of your project and the amount of time you have to invest in development.
We started by going down memory lane on the advent and rise of frameworks, and their wars in recent times. Next, we delved into React to learn about its brief history and also Svelte's. Later on, we compared both frameworks based on performance, bundle size, community support, and maintenance.
The decision between Svelte and React comes down to the needs of your project. If you’re looking for a lightweight, fast-performing framework that’s easy to learn, then Svelte may be the best choice. On the other hand, if you need a powerful framework that can handle complex applications, then React may be the better option.
