browser-router

A simple router for one page browser apps.

WHY

This is an effort of abstracting the routing such that applications can utilize a similar router on the client as on the server. The server counterpart is yet to be built.

INSTALL

npm install --save browser-router

USE

> var router = require('browser-router');

API

route(path, params, title)

> router.route('/login', { next: '/secret' }, 'Log In');

Make the router execute a route. This does a browser pushState to change the URL and params, while keeping the client app running.

onRoute(handler)

router.onRoute(function myHandler(route, params, title) {
	// handle this change in browser state
});

Catch an incoming route from the browser. This happens when:

• The user changes the route
• Browser back button, or back()
• Browser forward button, or forward()
• route()
• setPath()
• setParams(), setParam(), removeParam(), toggleParam()

Changes in the title do not cause routes. It is provided to the route handler as a convenience.

offRoute(handler)

> router.offRoute(myHandler);

Remove a handler that was listening to the router via onRoute.

getPath()

> router.getPath();
'/login'

Grab the current path. Excludes search query and hashstring parameters.

setPath()

> router.setPath('/login/securely');

Change the current path, causing a route.

getTitle()

> router.getTitle();
'Log In'

Get the title of the current location.

setTitle()

> router.setTitle('Secure Log In');

Set the title of the current location. This alters the current spot in history and does not cause a route.

getParams()

> router.getParams();
{ next: '/secret' }

Grab the current parameters object from the search query.

getParam(paramName)

> router.getParam('next');
'/secret'

Grab a single search query string parameter.

setParams(params)

> router.setParam({ next: '/secret/extra_secret', rememberMe: null });

Set a new params object, replacing the query string, causing a route.
This example would route to ?next=/secret/extra_secret&rememberMe
When the values are null, the param will be present but have no value, like the rememberMe param in the example.

hasParam(paramName)

> router.hasParam('rememberMe')
true

Checks for the presence of an item in the query string.
Useful for checking flags in the query, IE when the query string is ?next=/secret&rememberMe

setParam(paramName , value)

> router.setParam('securityLevel', '3')

Set a single parameter in the query string without wiping out the rest of the params. Causes a route.
This example would route to ?next=/secret/extra_secret&rememberMe&securityLevel=3
When the value is missing or null, the param will be present but have no value, like the rememberMe param in the example above.

removeParam(paramName)

> router.removeParam('securityLevel')

This example would route to ?next=/secret/extra_secret&rememberMe
Removes a parameter from the search query string. Mostly the inverse of setParam.

toggleParam(paramName , value)

> router.toggleParam('rememberMe')

This example would route to ?next=/secret/extra_secret
Toggles the presence of a param in the query string. If setting the param, use the provided value.
