#Route

#Introduction

The Route class represents a resolved route object in @esmx/router. Each navigation produces a Route instance containing complete information about the matched path, parameters, query strings, and associated metadata.

#Type Definitions

#RouteType

• Type Definition:

enum RouteType {
    push = 'push',
    replace = 'replace',
    restartApp = 'restartApp',
    go = 'go',
    forward = 'forward',
    back = 'back',
    unknown = 'unknown',
    pushWindow = 'pushWindow',
    replaceWindow = 'replaceWindow',
    pushLayer = 'pushLayer'
}

Indicates how the navigation was triggered:

• push: Standard forward navigation (adds history entry)
• replace: Replaces current history entry
• restartApp: App restart navigation
• go: Programmatic history traversal via router.go()
• forward: Forward navigation via router.forward()
• back: Backward navigation via router.back()
• unknown: Navigation triggered by browser popstate events
• pushWindow: Opens navigation in a new window
• replaceWindow: Replaces current window location
• pushLayer: Opens navigation in a layer

#RouteLocation

• Type Definition:

interface RouteLocation {
    path?: string;
    url?: string | URL;
    params?: Record<string, string>;
    query?: Record<string, string | undefined>;
    queryArray?: Record<string, string[] | undefined>;
    hash?: string;
    state?: RouteState;
    keepScrollPosition?: boolean;
    statusCode?: number | null;
    layer?: RouteLayerOptions | null;
    confirm?: RouteConfirmHook | null;
}

Route location object used for programmatic navigation:

• path: Route path
• url: Full URL string or URL object
• params: Route parameters for dynamic segments
• query: Query string parameters (single values)
• queryArray: Query string parameters (array values for repeated keys)
• hash: URL hash fragment
• state: Custom state data persisted in history
• keepScrollPosition: When true, maintains current scroll position after navigation
• statusCode: HTTP status code for server-side responses
• layer: Layer configuration options
• confirm: Custom confirm handler overriding default route transition logic

#RouteLocationInput

• Type Definition:

type RouteLocationInput = RouteLocation | string;

Input type for navigation methods. Can be a simple path string or a RouteLocation object.

// String shorthand
router.push('/user/123');

// Object form
router.push({
    path: '/user',
    query: { id: '123' },
    hash: '#profile'
});

#Instance Properties

#type

• Type: RouteType
• Read-only: true

The navigation type that created this route.

#path

• Type: string
• Read-only: true

The path relative to the router base. For matched routes, this is the path with the base prefix removed. For unmatched routes, this equals the full pathname.

// With base URL 'https://example.com/app/'
// Navigating to '/app/user/123'
route.path // '/user/123'

#fullPath

• Type: string
• Read-only: true

The complete path including query string and hash.

route.fullPath // '/user/123?tab=profile#bio'

#url

• Type: URL
• Read-only: true

The full URL object for this route.

route.url.href     // 'https://example.com/app/user/123?tab=profile#bio'
route.url.pathname // '/app/user/123'
route.url.origin   // 'https://example.com'

#params

• Type: Record<string, string>
• Read-only: true

Dynamic route parameters extracted from the path. For parameters with multiple matches, contains the first value.

// Route config: { path: '/user/:id' }
// URL: '/user/123'
route.params // { id: '123' }

#paramsArray

• Type: Record<string, string[]>
• Read-only: true

Dynamic route parameters in array form, useful for parameters that can match multiple segments.

#query

• Type: Record<string, string | undefined>
• Read-only: true

Parsed query string parameters. For repeated keys, contains the first value.

// URL: '/search?q=vue&page=1'
route.query // { q: 'vue', page: '1' }

#queryArray

• Type: Record<string, string[] | undefined>
• Read-only: true

Query string parameters in array form, useful for repeated query keys.

// URL: '/filter?tag=vue&tag=react'
route.queryArray // { tag: ['vue', 'react'] }

#hash

• Type: string
• Read-only: true

The URL hash fragment (including the # prefix).

// URL: '/page#section-2'
route.hash // '#section-2'

#meta

• Type: RouteMeta
• Read-only: true

Route metadata from the matched route configuration. Returns an empty object if no route is matched.

// Route config: { path: '/admin', meta: { requiresAuth: true } }
route.meta // { requiresAuth: true }

#matched

• Type: readonly RouteParsedConfig[]
• Read-only: true

Array of matched route configurations from parent to child. Empty array if no route matches.

// Nested routes: /user/profile
route.matched // [userConfig, profileConfig]
route.matched.length // 2

#config

• Type: RouteParsedConfig | null
• Read-only: true

The last (deepest) matched route configuration. null if no route matches.

if (route.config) {
    console.log('Matched route path:', route.config.path);
}

#state

• Type: RouteState
• Read-only: true

Custom state data associated with this route, persisted in browser history.

// Navigation with state
router.push({ path: '/checkout', state: { cartId: 'abc' } });

// Accessing state
route.state // { cartId: 'abc' }

#keepScrollPosition

• Type: boolean
• Read-only: true

Whether the navigation should maintain the current scroll position rather than scrolling to top.

#isPush

• Type: boolean
• Read-only: true

Whether this route was created by a push-type navigation (push, pushWindow, pushLayer).

#statusCode

• Type: number | null
• Read-only: true

HTTP status code for server-side rendering redirects.

#req

• Type: IncomingMessage | null
• Read-only: true

Node.js HTTP request object (available during SSR).

#res

• Type: ServerResponse | null
• Read-only: true

Node.js HTTP response object (available during SSR).

#context

• Type: Record<string | symbol, any>
• Read-only: true

Shared context object from the router options.

#Instance Methods

#clone()

• Returns: Route

Creates a copy of the current route instance with the same configuration and state.

const routeCopy = route.clone();
