tiny-regex-route-resolver

A super tiny regex route resolver

Implementation

the resolver appends / to the end of your pathname if its missing

var routeResolver = require('tiny-regex-route-resolver')
var routes = [
  {
    regex: /^((\/404\/)?)$/g,
    someKey: function() {}
  },
  {
    regex: /^((\/hello\/world\/)?)$/g
    anything: 'hello world'
  },
  {
    regex: /^(\/(post)\/([\w\d-_+]{1,})\/)$/g
  }
]

var routingLocation = history.location || window.location
var route = routeResolver(routingLocation.pathname, routes, routes[0]) // routes[0] is our 404 in this case

Returned Result

  {
    route: {
      regex: YOUR_REGEX,
      anything: ELSE_YOU_ADDED
    },
    pathname: THE_PATHNAME_YOU_PARSED_BUT_ALWAYS_ENDING_IN /
  }

Anatomy of a regex route

//g - basic regex start and end. regex is not a string, there is no need to wrap it in '' or ""

\/ - escaped /

\/(posts)\/ - a single section of path

([\w\d-_+]{1,}) - a wildcard that supports words (a-Z), digits (0-9), and - _ +

Putting it all together

/^(\/(hello)\/(world)\/([\w\d-_+]{1,})\/)$/g = /hello/world/Some3-val_4+ue/
