Router package for Frint


Guide

Installation

With npm:

$ npm install --save frint-router

Via unpkg CDN:

<script src="https://unpkg.com/frint-router@latest/dist/frint-router.min.js"></script>
 
<script>
  // available as `window.FrintRouter`
</script> 

Usage

The classes exported by this package are all independent and can be used as is.

import HashRouterService from 'frint-router/HashRouterService';
// import BrowserRouterService from 'frint-router/BrowserRouterService';
// import MemoryRouterService from 'frint-router/MemoryRouterService';
 
const router = new HashRouterService();
const subscription = router.getHistory$().subscribe(function (history) {
  console.log(history);
  // {
  //   length: 1,
  //   location: { ... }, // Object liked `window.location`
  //   action: 'PUSH',
  // }
});

The subscription will keep emitting new values every time there is a change in history.

Convention

To connect it well with other packages, we need to follow a convention of using the provider name router:

import { createApp } from 'frint';
import HashRouterService from 'frint-router/HashRouterService';
 
const RootApp = createApp({
  name: 'MyRootApp',
  providers: [
    {
      name: 'router',
      useFactory: function () {
        return new HashRouterService();
      },
      cascade: true,
    }
  ],
});

Direct imports

It is advised to import the appropriate router service class directly from the package, to make sure you are only bundling the services you explicitly need.

// will bundle only the individual HashRouterService
import HashRouterService from 'frint-router/HashRouterService';
 
// will bring ALL the service classes
import { HashRouterService } from 'frint-router';

API

The package exports three classes:

  • BrowserRouterService: uses HTML5 History API
  • HashRouterService: For legacy browsers
  • MemoryRouterService: useful for tests

All of them implement the same set of methods.

  • options.cacheLimit (Number): Maximum limit of entries to cache, set to 10000 by default.

getHistory$

getHistory$()

Streams history as it changes over time.

Returns

Observable: Streams history Object.

Structure of history object:

{

  location: { ... }, // like `window.location`
  action: 'PUSH' // either PUSH, REPLACE, or POP
}
