API Reference

Detailed API documentation is available in the api/ directory, organized to match the official Vue Router API documentation structure:

Router API (api/router.md)

• createRouter() - Creating a router instance
• Router instance methods: addRoute(), removeRoute(), hasRoute(), getRoutes(), push(), replace(), go(), back(), forward()
• Router instance properties: currentRoute, options

Route Records API (api/route-records.md)

• Route record types and properties
• Route configuration options

Composition API (api/useRouter-useRoute.md)

• useRouter() - Access router instance in setup
• useRoute() - Access current route in setup

Navigation Helpers (api/navigation-helpers.md)

• Navigation helper functions and utilities

Components API (api/router-link-router-view-components.md)

• RouterLink component props and usage
• RouterView component props and usage

History Modes API (api/history-modes-api.md)

• createWebHistory() - HTML5 history mode
• createWebHashHistory() - Hash mode
• createMemoryHistory() - Memory mode

Error and Failure Types (api/error-and-failure-types.md)

• Navigation failure types
• Error handling

To use API reference:

1. Identify the API you need help with
2. Load the corresponding API file from the api/ directory
3. Find the API signature, parameters, return type, and examples
4. Reference the linked example files for detailed usage patterns
5. All API files include links to relevant example files in the examples/ directory

Best Practices

1. Use named routes: Use named routes for better maintainability and refactoring
2. Lazy load routes: Use dynamic imports for route components to enable code splitting
3. Type safety: Use TypeScript with typed routes for better type safety
4. Navigation guards: Use navigation guards appropriately (global, per-route, in-component)
5. Route meta: Use route meta fields for custom data and permissions
6. History mode: Choose the appropriate history mode based on deployment environment
7. Scroll behavior: Configure scroll behavior for better UX
8. Error handling: Handle navigation failures gracefully
