route-node

A package to create a tree (trie) of named routes, allowing you to build and match routes.

$ npm install route-node --save

Creating your tree

To read about how to define paths, look at path-parser README

import rootNode from 'route-node'

// Create nodes
const usersNode = new RouteNode('users', '/users', [
  new RouteNode('list', '/list'),
  new RouteNode('view', '/view/:id')
])

// You can also use plain objects
const ordersNode = new RouteNode('orders', '/orders', [
  { name: 'pending', path: '/pending' },
  { name: 'completed', path: '/completed' },
  { name: 'view', path: '/view/:id' }
])

// Creating a top root node
const rootNode = new RouteNode('', '', [ordersNode, usersNode])

// Add nodes programmatically
rootNode.add(new RouteNode('home', '/home'))

/ paths (empty paths)

When using a deeply nested / path, it will automatically be matched when its parent is matched.

const tree = new RouteNode('', '', [
  new RouteNode('admin', '/admin', [
    new RouteNode('home', '/'),
    new RouteNode('users', '/users')
  ])
])

tree.matchPath('/admin') // => { name: 'admin.home', params: {} }
tree.buildPath('admin.home', {}, { trailingSlashMode: 'never' }) // => '/admin'

Options

const node = new RouteNode('admin', '/admin', [], options)

Where options can contain:

Building and matching routes

node.buildPath(routeName: string, params?: object, options?: BuildOptions): string

rootNode.buildPath('users.view', { id: 1 }) // => "/users/view/1"

Performance

Node children need to be sorted for matching purposes. By default this operation happens after having added all routes.

matchPath(path: string, options?: MatchOptions): RouteNodeState | null

rootNode.matchPath('/users/view/1')
// => {name: "users.view", params: {id: "1"}}
