A tiny JS router that makes no assumptions about its usage.
- ES6 module.
- Support browser, node, deno.
- Pure functional design.
- Tiny codebase, very understandable.
- Everything is a plugin.
- Pre-built runtimes for easy use.
- Designed following the principles of UNIX philosophy.
- Very well tested.
- Ridiculously small API. After reading this file you will
understand
Wand
better than me.
Wand
makes no assumptions about the environment it will be used in, and this
example can be easily migrated to a server-side router or any other type of
application.
<body>
<nav>
<a href="#/">Home</a> |
<a href="#/hello/Mary">Hello Mary</a> |

This example already makes use of the queryParser
plugin
and
implements the runtime
of a hash router.
import {hashRouter} from "https://cdn.jsdelivr.net/gh/marcodpt/wand/index.js"
This example is for those who want a more customized experience to create
their own runtime
and eventually make use of plugins
.
import {wand, queryParser} from "https://cdn.jsdelivr.net/gh/marcodpt/wand/index.js"
Runtimes
are thin layers built on top of Wand
with the aim of bringing
simplicity to a specific use, they are open to contributions.
Made to be used in the browser, it already has the queryParser
plugin by
default.
Plugins
can modify the state
with each change
of route, and were designed
to be easy to develop without changing the way the Wand
core works.
Enabling maximum flexibility and contributions.
The default parser for query string due to its simplicity.
Adds the Query
property to the state
.
Parsed query string.
Runtimes
are built on top of the library.
And the plugins
are designed for it.
The idea is to bring a simple router to your core but at the same time with a
complete plugin
system and easy-to-use runtimes
.
Optional function called once to create the initial state
(this must be an object
).
Object that defines the possible routes
.
Accepts *
to match any path and :param
to declare variable.
A function that will be called whenever route
is matched in a route change
.
All other args
passed by the change
function will be passed to the
action
.
An optional function that will be called before the new route
action
, with
the state
of the new route
to end the current route
.
If it is not a done
function, it will be treated as a response
and
returned in the change
function.
An optional array of plugins
, which are executed sequentially with each
route
change
and which can modify the state
before the action
associated with the new route
or the done
function associated with the old
route
are called.
The router runtime
.
Whenever called, it will trigger a change
of route
, with the
url
(string
) being associated with the state
.
All other args
will be passed to the action
.
Optional function to terminate the runtime
, receives the current state
of
the route
as a parameter.
Calls the finish
function of the runtime
with the contents of the current
state
, and from then on any call to the change
function within the
runtime
will be ignored.
The state is initialized by the init
function or as an empty object
(if init
is not passed).
Listed here are the state
properties that are modified with each route
change
. Note that plugins
can also modify state
properties.
The url
as passed to the change
function.
The route
that matched as declared.
The part of the url
before the ?
.
Object containing the variables declared in the route
with the associated
values in the current path
.
The part of url
after the ?
.
