Router.js
Router.js is a client-side JavaScript routing library designed for single-page applications. It maps browser URL patterns to named handlers and manages hierarchical route states, allowing applications to construct nested user interfaces and share parent contexts across child transitions.
The library coordinates state changes through promise-based asynchronous transition management, waiting for model data to resolve and lifecycle hooks to execute before entering a target route. It supports URL parsing and generation, component navigation, and event bubbling that propagates triggered actions backward through parent route handlers for shared logic propagation and method overriding.
Transitions can be intercepted to handle request aborts, redirection flows, and centralized error recovery during navigation states.
Features
- Route Pattern Matchers - Maps incoming URL strings to named handler patterns and builds valid destination URLs from structured parameters.
- Web Application Route Navigations - Maps incoming URLs to application handlers and manages application state transitions smoothly during user navigation.
- Asynchronous State Transition Orchestration - Coordinates multi-step route transitions by waiting for asynchronous model hooks and data loaders to resolve.
- Transition Interception Handlers - Handles application state transitions by intercepting navigations, waiting for pending promises, and supporting aborts or redirects.
- Hierarchical View Nesting - Organizes routes hierarchically to construct complex master-detail views and nested user interfaces.
- Single Page Applications - Coordinates nested route hierarchies, view states, and lifecycle hooks for single-page web applications.
- Asynchronous Transition Control - Waits for pending promises returned by model hooks or data loaders to resolve before completing route transitions.
- Client-Side Route Mapping - Maps browser URL changes to application states and handlers, enabling single-page application navigation without page reloads.
- Named Handler Pattern Mappers - Maps browser URL patterns to named handlers and parameters, allowing applications to define navigation paths easily.
- Application Route Managers - Maps URL changes to specific views and coordinates state changes smoothly during single-page application navigation.
- Nested Routing - Organizes routes hierarchically to construct nested user interfaces and share parent contexts across child transitions.
- Client-Side JavaScript - Maps URL patterns to handlers, manages hierarchical state transitions, and resolves asynchronous route models.
- URL Data Parsing - Parses raw URL strings into structured, typed data to support application routing and state management.
- Hierarchical Routing - Organizes routes in a nested tree structure to construct complex view hierarchies and share parent contexts.
- State Transition Lifecycle Hooks - Executes sequential hooks during state changes to fetch required model data, validate permissions, and handle errors.
- Asynchronous Data Loading - Loads required data models through promises and lifecycle hooks before entering a route.
- Asynchronous Route Model Resolvers - Loads required data models through asynchronous hook execution before entering a target route.
- Transition Interception and Recovery Mechanisms - Intercepts active transitions to handle aborts, redirections, and centralized error recovery during navigation states.
- Event Bubbling Mechanisms - Propagates triggered events backward through parent route handlers to enable shared logic and method overriding.
- Router Event Bubbling Systems - Propagates triggered actions backward through parent route handlers to share behavior and override methods across transitions.
- Lifecycle-Based Route Validators - Executes lifecycle hooks before entering routes to fetch required model data, validate permissions, and handle errors.
- URL Component Construction - Builds valid URL strings from route names, primitive parameters, or serialized objects for component navigation.
