The web development landscape constantly expands and brings multiple choices for front-end developers. Developers seem burdened with a decision. Which UI framework do you use? Do you use React, a popular choice with a huge ecosystem? Or is it Vue, a lighter option? What about using plain JavaScript with a few web components?
Many options are on the market, but the two admired options for developers are SolidJS and Svelte. A 2024 survey of Stack Overflow proves that the preferences of the developers’ community are shifting.
The survey asked participants to name their favorite front-end frameworks. You may be surprised that React and Vue were not among the most popular choices. Most of the participants voted in favor of Svelte and SolidJS.
This signals a paradigm shift in front-end development. So, let’s conduct a detailed comparison of SolidJS and Svelte and highlight their distinctive features.
Here, you’ll have a complete understanding of how both frameworks function and what pros and cons they have. Moreover, you will know which framework is more suitable for your web development projects.
So, without any further ado, let’s start reading!
What is SolidJS?
SolidJS is a modern JavaScript library that focuses on reactivity and performance. It aims to build simple yet powerful user interfaces. This framework helps developers develop efficient and reusable web apps.
Inspired by React, SolidJS has some extraordinary features and optimizations. This makes SolidJS more useful than many other UI libraries like Vue, React, and Angular. Moreover, SolidJS ensures that its user interface reacts fast to changes in the base data.
The following are the top features of SolidJS:
- Server-side rendering
- Fine-grained reactive system
- Tiny footprint but has a big impact
- Excellent support for TypeScript
- Highly-efficient DOM handling
- Expressive and efficient JSX syntax
- Fine-grained dependency tracking
What is Svelte?
Svelte is a modern JS framework. Developers worldwide use Svelte to create static and user-friendly web applications. Whatever the project type, you can employ Svelte to create its single and reusable components. You can also use this framework to build larger applications on Vue, React, or other frameworks.
The following are the top features of Svelte:
- Scoped styles
- Declarative syntax
- Built-in functionality
- Top-notch build step
- No runtime framework
- Reactivity without boilerplate
- Built-in animation capabilities
SolidJS vs Svelte: Top Uses
SolidJS and Svelte are gaining immense popularity among website developers in today’s highly competitive web development. They find building UI with these frameworks quite helpful and fun. Both frameworks offer their advantages.
Let’s dive into the uses of SolidJS and Svelte and compare their features!
Uses of SolidJS
Single-page applications: SolidJS has strong reactivity and efficient rendering capabilities. These features make SolidJS the best choice for developing single-page applications (SPAs).
UI with complex state management: When your application project requires complex state management, you can use SolidJS as a framework. Its strong reactive system quickly handles complex UI scenarios.
Interactive components: The strong reactive nature of SolidJS creates interactive components. It includes dynamic forms and live data visualizations.
Performance-critical applications: SolidJS manipulates the DOM directly. This feature enables SolidJS to build performance-critical apps.
Uses of Svelte
Interactive web applications: The efficient code generation of Svelte develops interactive web applications. Svelte is a great choice for development projects where performance is extremely important.
Data visualization: Svelte has strong animation capabilities and reactivity. So, it enables developers to use it to develop engaging data visualizations.
Mobile applications: Svelte isn’t limited to websites. Its benefits extend to mobile apps as well. Developers use it to create a responsive user experience.
Real-time collaborative editing: Developers also prefer using Svelte when it comes to developing real-time collaborative editing features.
Advantages of SolidJS
- SolidJS is easy to learn and use.
- SolidJS has a small bundle size.
- SolidJS has smooth interactions.
- SolidJS has seamless JSX integration.
- SolidJS has fine-grained dependency tracking.
Disadvantages of SolidJS
- SolidJS has a smaller ecosystem.
- SolidJS is difficult to learn for JSX novices.
- SolidJS supports TypeScript but has limited tooling.
Advantages of Svelte
- Svelte has highly optimized runtime code.
- Svelte simplifies component development.
- Svelte has no runtime framework overhead.
- Svelte has strong built-in animation capabilities.
- Svelte scoped styles reduce the chances of style conflicts.
Disadvantages of Svelte
- Svelte has a smaller ecosystem.
- Svelte has a complex build setup.
- Svelte is difficult to learn for JSX Veterans.
SolidJS vs Svelte: 5 Key Differences
Now you know the features, applications, advantages, and disadvantages of SolidJS and Svelte. Let’s look at the five key differences between SolidJS and Svelte!
Reactivity Approach
A fine-grained reactivity system of SolidJS ensures updates where needed. It enables developers to provide users with exceptional performance.
On the other hand, Svelte uses a build-time reactivity approach. This framework shifts computational heavy lifting to the compilation step. It ultimately produces optimized runtime code and ensures faster execution in the browser.
Bundle Size
SolidJS has a compact bundle size. In projects where minimum load time and performance are essential, SolidJS performs the best. Whereas Svelte implements a build step. It generates highly optimized code and ensures small bundles without the need for a runtime framework.
Animation Capabilities
SolidJS offers basic animation capabilities, which are highly beneficial for projects with simple animation requirements. However, when it comes to animation features, Svelte stands out. It has built-in animation features that create a top-notch user experience.
Scoped Styles
SolidJS does not natively support scoped styles. It may lead to style conflicts when working on a large-scale project. However, Svelte has extraordinary scoped styles. Usually, projects come across unintended style clashes, but using Svelte reduces their probability. This will also enhance the code maintainability of your project.
Learning Curve
SolidJS has a gentle learning curve, making it highly approachable for software developers with varying skill levels. Svelte, on the other hand, offers an easy learning curve. Its declarative syntax and lack of boilerplate code enable quick adoption and efficient development.
