Expo Router vs. React Navigation

Expo Router and React Navigation represent two of the most popular navigation solutions for React Native applications, each with distinct approaches to handling navigation across mobile platforms. According to the State of React Native 2023 survey, Expo Router has rapidly gained popularity to become the second most widely used navigation library in the ecosystem, following the well-established React Navigation. This comprehensive analysis explores the relationship between these two libraries, their key differences, and considerations for choosing between them for your next React Native project.

The Relationship Between Expo Router and React Navigation

Contrary to what some developers might assume, Expo Router and React Navigation are not competing libraries from different teams. Both are developed by the Expo team, with Expo Router built as a layer on top of React Navigation. This relationship is important to understand because Expo Router is actually a superset of React Navigation, meaning you can use any React Navigation components and APIs within an Expo Router project.

The fundamental architecture allows Expo Router to leverage the mature foundation of React Navigation while introducing a more streamlined developer experience. This means developers aren’t forced to choose between the libraries’ core navigation capabilities, but rather between different approaches to organizing and defining navigation structures. When using Expo Router, you’re effectively using React Navigation under the hood, but with an alternative API for defining routes.

Since Expo Router is built on React Navigation, it inherits many of the native optimizations and platform-specific behaviors that make React Navigation powerful. This includes the use of native stack navigators for performant transitions on both iOS and Android.

Core Architectural Differences

The most significant distinction between these libraries is their fundamental approach to defining navigation. React Navigation follows a traditional programmatic approach where routes are explicitly registered through JavaScript configuration. In contrast, Expo Router introduces a file-based routing system similar to modern web frameworks like Next.js, Nuxt, and SvelteKit.

With Expo Router, the file system itself becomes your routing mechanism. When you add a file to the app directory, that file automatically becomes a route in your navigation system without requiring additional configuration. This convention-over-configuration approach significantly reduces boilerplate code and makes the relationship between your code organization and navigation structure more intuitive and predictable.

React Navigation, while more verbose, offers explicit control over every aspect of your navigation structure. Routes must be manually registered, relationships between screens must be explicitly defined, and navigation options require specific configuration. This approach provides maximum flexibility but introduces more complexity, especially as applications grow larger.

Feature Comparison

Expo Router’s Key Features

Expo Router brings several compelling features to the React Native ecosystem:

Native performance is maintained because Expo Router is built on top of React Navigation’s foundation, ensuring that all navigation transitions and behaviors are truly native and platform-optimized by default.

Automatic deep linking is perhaps one of the most significant advantages of Expo Router. Every screen in your application is automatically deep-linkable, making any route in your app shareable through links without additional configuration. This feature is particularly valuable for applications that benefit from content sharing.

The offline-first architecture ensures that applications remain functional even without an internet connection. Apps are cached and run offline-first, with automatic updates when you publish a new version. This system handles all incoming native URLs without requiring a network connection or server.

Route optimization is another benefit, as routes are automatically optimized with lazy-evaluation in production and deferred bundling in development. This approach ensures that your application only loads the necessary code for each route, improving performance.

Expo Router also enables build-time static rendering on web, allowing for SEO and content discoverability — a crucial feature for applications with both web and mobile presences.

React Navigation’s Strengths

React Navigation offers a more extensive set of features and APIs compared to Expo Router’s more focused approach:

A wide variety of navigation types are available, including stack navigators, tab navigators, drawer navigators, and more specialized options. This diversity allows developers to implement virtually any navigation pattern found in modern applications.

Advanced customization is a major strength, with React Navigation providing fine-grained control over transitions, headers, and navigation behaviors. This level of customization is valuable for applications with unique branding requirements or non-standard navigation patterns.

The extensive ecosystem surrounding React Navigation includes numerous third-party libraries, extensions, and community-developed navigation patterns. This ecosystem has evolved over years of widespread adoption and can provide solutions for even the most specialized navigation requirements.

Developer Experience and Usability

The developer experience differs significantly between these libraries, with important implications for productivity and maintainability.

Expo Router emphasizes simplicity and intuitiveness. Its file-based routing approach feels natural to developers coming from modern web frameworks and reduces cognitive overhead when managing navigation structure. As one experienced developer on Reddit noted, “Having worked with RN commercially for over 5 years, I strongly advise to use Expo Router for the fact that it’s significantly easier to implement”.

The simplification of deep linking implementation represents a particular advantage. In React Navigation, implementing and maintaining deep linking configuration can become increasingly complex as applications grow. Expo Router handles this automatically, making it “around 95% easier to use” according to the same developer.

React Navigation provides more granular control but requires more configuration and code. This approach can become unwieldy in larger projects, with one developer noting that React Navigation “can become increasingly complex and almost unmanageable in larger projects. Writing a linking config is increasingly complex, and handling deep linking is another task that often shouldn’t be taken lightly”.

Community Support and Adoption

The community landscape around these libraries presents interesting considerations:

React Navigation has historically enjoyed broader adoption and a larger community, with more extensive documentation and resources available. Its longer presence in the ecosystem has resulted in a wealth of tutorials, examples, and community-developed solutions.

Expo Router, while newer, is rapidly gaining adoption. Its rise to become the second most popular navigation solution according to the State of React Native 2023 survey demonstrates strong developer interest in its approach. As an experienced developer on Reddit noted, “Expo router looks like it might become the de facto way to write routes in Expo because of the DX”.

The backing of the Expo team for both libraries ensures ongoing development and support. This shared lineage means that expertise in one library often transfers to the other, simplifying the learning curve for developers transitioning between them.

Use Case Considerations

The choice between these libraries often depends on specific project requirements and constraints:

When to Choose Expo Router

Expo Router is particularly well-suited for new projects, especially those already using the Expo ecosystem. Its simplicity and automatic handling of common navigation challenges make it an excellent choice for rapid development.

Applications benefiting from deep linking and content sharing, such as social media apps, content platforms, or e-commerce applications, can leverage Expo Router’s automatic deep linking to create more engaging experiences.

Developers familiar with file-based routing from web frameworks like Next.js will find Expo Router’s approach intuitive and natural. The similarity in mental models reduces the learning curve and can increase productivity.

Projects prioritizing developer experience and maintainability may prefer Expo Router’s more streamlined approach. As one developer put it, “Expo router makes it feel like there’s one less thing to think about”.

When to Choose React Navigation

Applications requiring highly customized navigation patterns or specialized transitions may benefit from React Navigation’s more extensive customization options.

Projects outside the Expo ecosystem or those using React Native CLI directly might find React Navigation a more natural fit, though it’s worth noting that Expo Router can be used in bare React Native projects as well.

Teams with extensive experience in React Navigation might prefer to leverage their existing knowledge rather than adopting a new approach, particularly for maintaining or extending existing applications.

Implementation Complexity

The implementation complexity of these libraries differs significantly, with important implications for development velocity and code maintainability.

Expo Router substantially reduces boilerplate code through its file-based approach. Navigation structures that might require dozens or even hundreds of lines of configuration code in React Navigation can be implicitly defined through simple file organization in Expo Router. This reduction in explicit configuration code can make applications more maintainable and easier to understand.

Deep linking implementation represents a particular area where complexity differs dramatically. In React Navigation, proper deep linking support often requires extensive configuration and maintenance as the application evolves. Expo Router handles this automatically, making deep linking a built-in feature rather than an additional development task.

The simplicity of Expo Router can be particularly valuable for teams with varying levels of expertise or for projects that might be maintained by different developers over time. The intuitive file-based approach reduces the learning curve and makes the navigation structure more immediately comprehensible to new team members.

Conclusion

Both Expo Router and React Navigation offer compelling approaches to navigation in React Native applications, with the choice between them depending largely on project requirements and developer preferences. Expo Router’s file-based approach simplifies many common navigation tasks and provides an intuitive mental model that many developers find appealing, particularly those with experience in modern web frameworks. React Navigation offers more extensive customization options and a longer track record in the ecosystem.

For developers starting new projects, especially within the Expo ecosystem, Expo Router represents an increasingly popular choice due to its simplified approach and automatic handling of common navigation challenges. As one senior developer put it, “I intend to also use Expo router for any new projects going forwards” . For projects requiring highly specialized navigation patterns or extensive customization, React Navigation continues to provide the flexibility and control necessary for complex requirements.

The shared lineage of these libraries — both developed by the Expo team — means that developers aren’t forced to choose between core capabilities, but rather between different approaches to organizing and defining navigation structures. This relationship also suggests that both libraries will continue to evolve and improve, benefiting the broader React Native ecosystem regardless of which approach developers choose for their specific projects.
