Rooter is a small, but potentially useful, client-side routing library with small API that is backed by browser's History API.
Here we will create new instance of router by calling rooter
function which
can accept optional argument that is id
of root DOM element in which all views are
going to be rendered. If element is passed smooth transition will be applied on
route change.
var router = rooter("app");
To configure type and duration of transition you can use configureTransition
method to which you pass plain JavaScript object with effect
, time
and
applyAfter
properties. Time should be in milliseconds.
router.configureTransition({
time: 400,
effect: "ease-in",
applyAfter: 200
});
After instantiation we can add routes by calling when
method on provided
object. It looks like this, also it supports chaining.
router.when("/", function() {
// custom logic
});
Router also support URL parameters all of which are decoded with browser
decodeURIComponent
function before being passed to attached handler.
router.when("/user/:id", function(params) {
console.log(params); // which for example could contain { id: "1" }
});
Middleware functions are another part of router. They are optional but if you want to add them you can do so by passing an array with desired functions as second argument.
function authenticate() {
// logic
}
router.when("/profile/:id/edit", [authenticate], function(params) {
if(authenticated) {
// proceed
} else {
router.redirect("/login");
}
});
If you want to namespace routes you can use appropriately named namespace
method.
router.namespace("user")
To handle 404
pages you can use notFound
method by providing to it a custom
function. Defaults to empty function.
route.notFound(function() {
// for instance view.render("notfound");
});
Last step after adding desired routes and setting up error handling is to call start
function which will
monitor for changes on window.location
property.
router.start();
If you want to remove certain route you would call remove
method and pass path
to it...
router.remove("/secret");
To empty whole object you can call router.flush()
.
