As web development continues to evolve, the demand for efficient and performant components is higher than ever. React has been a prominent choice for building web applications, but developers are always on the lookout for tools and libraries that can help them streamline their workflows. One such tool is Stencil, a powerful compiler for building web components. In this blog post, we'll explore the advantages of using Stencil over pure React for building components.

1. Web Component Standard Compliance

Stencil is built around the Web Component standard, which provides a set of APIs for creating reusable custom elements. By adhering to this standard, Stencil components are framework-agnostic, making them compatible with not just React but also Angular, Vue, and even vanilla JavaScript. This broad compatibility is a significant advantage over React, which primarily targets React-based projects.

2. Improved Performance

Stencil focuses on performance optimization out of the box. It employs features like lazy-loading, asynchronous rendering, and efficient DOM updates to ensure that components load quickly and respond smoothly. React components can achieve good performance too, but Stencil's default settings are tuned for high performance, saving developers time and effort.

3. Optimized Bundle Size

Stencil excels in minimizing bundle sizes. It generates highly optimized JavaScript code and uses tree-shaking to eliminate dead code, ensuring that only the necessary components and dependencies are included in the final bundle. This leads to smaller bundle sizes compared to React, making your web applications faster to load.

4. Built-In TypeScript Support

Stencil comes with built-in TypeScript support, making it easier for developers to write type-safe components. While React also supports TypeScript, Stencil's TypeScript integration is seamless and well-documented, enabling developers to catch errors at compile time, rather than during runtime.

5. Cross-Framework Compatibility

Stencil's components can be used in a variety of frameworks and libraries, making them highly versatile. This allows for code reuse and sharing components between different projects or teams, which can lead to significant time and cost savings. React components, on the other hand, are typically tightly coupled with the React ecosystem.

6. Dependency Management

Stencil provides a straightforward way to manage dependencies with its built-in package manager. This simplifies the process of installing and updating libraries and ensures version compatibility. React, on the other hand, relies on external package managers like npm or yarn, which may require additional configuration and management.

7. Developer Experience

Stencil offers a great developer experience with a comprehensive CLI tool that includes a development server, live reloading, and component documentation generation. This streamlines the development process and helps developers focus on writing code rather than dealing with complex configurations.

8. Community and Ecosystem

While React boasts a vast and active community, Stencil has been steadily gaining traction. As more developers adopt Stencil, the ecosystem is growing, with an increasing number of third-party components and plugins becoming available. This diversification benefits developers looking for specific solutions.


Both React and Stencil have their strengths and are suitable for various use cases. However, if you're looking to build highly performant, cross-framework compatible web components with an optimized development experience, Stencil is an excellent choice. It leverages the Web Component standard, prioritizes performance, and minimizes bundle size. Additionally, its built-in TypeScript support, dependency management, and versatile compatibility make it a compelling alternative to pure React for component development. As the web development landscape evolves, Stencil's advantages continue to shine, offering developers new and efficient ways to create web components that stand out.
