Napoleon

An isomorphic JavaScript routing and HTML5 history library.

Quick Start

const Napoleon = require('napoleon');
const router = new Napoleon.Router();
router.mount({
    name: 'userprofile',
    method: 'GET',
    url: '/user/{userId}',
    handler: () => {
        console.log('Routed to user profile');
    }
});

router.route('GET', '/user/15'); // calls the handler above, logging "Routed to user profile" to console

Routing

Routes are stored in a tree structure for fast insertion and lookup.

Adding routes

mount({method = 'GET', url, handler, name})

• method: GET|POST|PUT|DELETE|etc - case insensitive, defaults to GET
• url: URL path to match, named variable parameters are identified by brackets: /user/{userId}
• handler: function which is called when the path is matched
  • parameters: key/value object with parameters pulled from the route and querystring
  • data: an argument that is passed through to the handler by the route method

URLs can be parameterized by wrapping one of the path segments in {} brackets. For example, when matching a route /user/{userId} anything in the segment following /user/ will be extracted into a userId value. Star characters can be used as a match-all: /users/{userId}/*

let router = new Napoleon.Router();
router.mount({
    name: 'userprofile',
    method: 'GET',
    url: '/user/{userId}',
    handler: parameters => {
        const {userId} = parameters;
        console.log(`user profile was called for user ${userId}`);
    }
});

Calling route handlers

Call route to trigger a route handler for a given path.

router.route('GET', url);

Retrieving route declaration object

You can retrieve the route object used when a route was mounted by calling matchRoute

const route = router.matchRoute('GET', url);
