Express like routing, as Custom Element or standalone, inspired by page.js.

app API

• app.get(path:string|RegExp, cb:Function[, cb2, ...]):app to subscribe one or more callbacks for the specified route
• app.delete(path:string|RegExp, cb:Function[, cb2, ...]):app to unsubscribe one or more callbacks for the specified route
• app.navigate(path:string[, operation:string = 'push']):void to navigate to the first matching route for the given path. By default, it pushes to the history but it could replace, if the second parameter is the replace string, or ignore.
• app.param(path:string|RegExp):app to subscribe to a specific parameter regardless of the route
• app.use(path:string|RegExp):app to subscribe a callback for a specific mount point or all of them

Example

The following is a basic example, also available live.

<script src="//unpkg.com/a-route"></script>

<!-- simply add `is="a-route"` to any link in your page -->
<a is="a-route" href="/test/?query=value">test query</a>

<!-- you can also add `no-propagation`, to stop propagation on click
    or you could add `replace` to replace state instead of pushing it -->
<a is="a-route" href="/test/OK" no-propagation replace>test OK</a>

<!-- unregistered routes will pass through `'*'` handler, if any -->
<a is="a-route" href="/whatever">test 404</a>

// import {app} from 'a-route';
// const {app} = require('a-route');
const {app} = ARoute;

// define routes
app
  .get('/test/?query=:query', function (ctx) {
    console.log(ctx);
    /*
    {
      "path": "/test/?query=value",
      "params": {
        "query": "value"
      }
    }
    */
  })
  .get('/test/:status', function (ctx) {
    console.log(ctx);
    /*
    {
      "path": "/test/OK",
      "params": {
        "status": "OK"
      }
    }
    */
  });

// intercept all unregistered calls
app.get('*',
  function (ctx, next) {
    console.log(ctx);
    /*
    {
      "path": "/whatever"
    }
    */
    next();
  },
  // will receive the ctx object too
  console.error
);
