router-trie

Usage

npm i router-trie

import { createTrie, matchTrie } from "router-trie";

const routesTrie = createTrie([
  {
    id: "root",
    children: [
      {
        id: "home",
        index: true,
      },
    ],
  },
]);

const matches = matchTrie(routesTrie, "/");

console.log(matches);
// [{ id: "root" }, { id: "home", index: true }]

Development

To install dependencies:

npm i

To run the playground:

npm start

To run the tests:

npm test

Visual of the trie structure:

Given the following routing config: routes.json

We get the following trie:

graph TD;
  0__{_ROOT_} --> 0_0__{_ROUTE_};
  0_0__{_ROUTE_} --> 0_0_0__{_INDEX_};
  0_0_0__{_INDEX_} --> 0_0_0_0__{_ROUTE_};
  0_0__{_ROUTE_} --> 0_0_1__{path-index};
