matchit 
Quickly parse & match URLs
Install
$ npm install --save matchit
Usage
const { exec, match, parse } = require('matchit');
parse('/foo/:bar/:baz?');
//=> [
//=> { old:'/foo/:bar', type:0, val:'foo' },
//=> { old:'/foo/:bar', type:1, val:'bar' },
//=> { old:'/foo/:bar', type:3, val:'baz' }
//=> ]
const routes = ['/', '/foo', 'bar', '/baz', '/baz/:title','/bat/*'].map(parse);
match('/', routes);
//=> [{ old:'/', type:0, val:'/' }]
match('/foo', routes);
//=> [{ old:'/foo', type:0, val:'foo' }]
match('/bar', routes);
//=> [{ old:'bar', type:0, val:'bar' }]
match('/baz', routes);
//=> [{ old:'/baz', type:0, val:'baz' }]
let a = match('/baz/hello', routes);
//=> [{...}, {...}]
let b = exec('/baz/hello', a);
//=> { title:'hello' }
match('/bat/quz/qut', routes);
//=> [
//=> { old:'/bat/*', type:0, val:'bat' },
//=> { old:'/bat/*', type:2, val:'*' }
//=> ]API
matchit.parse(route)
Returns: Array
The route is split and parsed into a "definition" array of objects. Each object ("segment") contains a val, type, and old key:
old— Theroute's original valuetype— An numerical representation of the segment type.0- static1- parameter2- any/wildcard3- optional param
val— The current segment's value. This is either a static value of the name of a parameter
route
Type: String
A single URL pattern.
Note: Input will be stripped of all leading & trailing
/characters, so there's no need to normalize your own URLs before passing it toparse!
matchit.match(url, routes)
Returns: Array
Returns the route's encoded definition. See matchit.parse.
url
Type: String
The true URL you want to be matched.
routes
Type: Array
All "parsed" route definitions, via matchit.parse.
Important: Multiple routes will require an Array of
matchit.parseoutputs.
matchit.exec(url, match)
Returns: Object
Returns an object an object of key:val pairs, as defined by your route pattern.
url
Type: String
The URL (pathname) to evaluate.
Important: This should be
pathnames only as anyquerystrings will be included the response.
match
Type: Array
The route definition to use, via matchit.match.
