Browser-friendly URL-template-based routing.

Oxgen maps an RFC 6570 URL template to a function.

(Code examples are CoffeeScript because we prefer it, but Oxygen is transpiled into modern JavaScript.)

import Router from "@dashkite/oxygen"

router = Router.create()

Router.add router, "/hello/{name}",
  name: "greeting"
  ({bindings}) ->
    console.log "Hello, #{bindings.name}"

dispatch "/hello/dan"

By itself, this is doesn't do much, but that's the idea: you can put anything in the function, and thus use routes for whatever you want, using whichever libraries or frameworks you want.

The Neon library provides combinators for dynamically rendering and updating Web pages. We can use Neon to construction the handlers for our routes.


npm i @dashkite/oxygen

Oxygen is intended to be used in the browser via a bundler like Web Pack. It may also be used in a server context, such as server-side rendering. The only parts of the API that depend on the DOM API are those that manipulate browser history: push, replace, and browse.



Create an instance of a router.

add router, template, data, handler

Add a route for the given template, it with the given data and the handler.

The handler should take an object with three properties:

  • path - the original path that matched the template
  • data - the data properties associated with the route
  • bindings- the values destructured from the template

The name property for the data element is required.

match router, path

Primarily intended for internal use, this will return the bindings and data for the route matching the given path.

dispatch router, description

Fires the handler that matches the description. The description may be a URL or path or a name with parameters. The latter case allows you to dispatch a route by name instead of by path. This is useful when you want to logically reference a route.


Dispatch Via Path
dispatch router, url: "/hello/dan"
Dispatch Via Name With Parameters
dispatch router, name: "greeting", parameters: name: "dan"

link router, description

Returns the URL for the given description. The description must include the route name and may include parameters.


assert.equal "/hello/dan",
  link router, name: "greeting", parameters: name: "dan"

push router, description

Pushes a URL onto the browser history (also known as push state). Description must include either a URL or a name with parameters. It may also include state, although Oxygen doesn't make use of this feature directly.


push router, url: "/hello/jay"

replace router, description

Replaces the current URL in the browser history. See push.

browse router, description

Like push followed by dispatch: pushes a URL onto the browser history and dispatches it.
