#Path.js ####Simple Javascript path management library

Installation

Include path.js in your HTML file. Path.js depends on [tags.js].

<script src="tags.js"></script>
<script src="path.js"></script>

Usage

#####Simple

var pathConfig = {
	"base": "/base/"
};

var path = new Path(pathConfig);
path.url("about") // /base/about

#####Advanced

var pathConfig = {
	"base": "/base/",
	"cdn": "http://cdn.com/",
	"lang": "en",
	"absolute": "http://example.com/base/",
	"tags": {
		"cdn": "{{cdn}}",
		"abs": "{{absolute}}",
		"base": "{{base}}",
		"lang": "{{lang}}",
		"absLang": "{{absolute}}{{lang}}",
		"inc": "include"
	},
	"prefixes": {
		"/cdn/": "{{cdn}}",
		"/abs/": "{{absolute}}"
	},
	"ignorePrefixes": ["http://", "https://", "mailto:", "#"]
};

var path = new Path(pathConfig);
path.url("about"); // /base/about
path.url("/abs/"); // http://example.com/base/
path.url("{{abs}}"); // http://example.com/base/
path.url("{{abs}}{{lang}}"); // http://example.com/base/en
path.url("{{absLang}}"); // http://example.com/base/
path.url("/cdn/image.jpg"); // http://cdn.com/image.jpg
path.url("http://www.google.com/image.jpg"); // http://www.google.com/image.jpg
path.url("{{inc}}/script.js"); // include/script.js

Options

#####Base The only required config parameter is "base". The "base" string will be appended only to unchanged paths. Useful when using relative paths in conjunction with HTML History API.

var pathConfig = {
	"base": "/base/",
	"cdn": "http://cdn.com/",
	"tags": {
		"cdn": "{{cdn}}"
	}
};

var path = new Path(pathConfig);
path.url("about"); // /base/about
path.url("{{cdn}}about"); // http://cdn.com/about

#####Tags Replacement tags can be used in any position within paths. Tags are referenced in paths with mustache-style curly braces: {{tagName}}

var pathConfig = {
	"base": "/base/",
	"tags": {
		"lang": "english",
		"region": "great-britain"
	}
};

var path = new Path(pathConfig);
path.url("about/{{lang}}"); // about/english
path.url("about/{{lang}}/canada"); // about/english/canada
path.url("about/{{lang}}/{{region}}"); // about/english/great-britain

Tag values can reference variables in the root of the config object.

var pathConfig = {
	"base": "/base/",
	"country": "great-britain",
	"tags": {
		"lang": "english",
		"region": "{{country}}" // references pathConfig.country
	}
};

var path = new Path(pathConfig);
path.url("about/{{lang}}/{{region}}"); // about/english/great-britain

#####Prefixes Prefixes are similar to tags, but are only replaced if found at the beginning of a path. Mustache-style curly braces are not necessary.

var pathConfig = {
	"base": "/base/",
	"cdn": "http://cdn.com/",
	"prefixes": {
		"/lang/": "/english/",
		"/cdn/": "{{cdn}}"
	}
}

var path = new Path(pathConfig);
path.url("/lang/united-states"); // /english/united-states
path.url("/no-change/lang/"); // /no-change/lang
path.url("/cdn/assets/image.jpg"); // http://cdn.com/assets/image.jpg

#####ignorePrefixes Path class will not change paths that begin with certain strings. Common examples would be "http://" or "mailto:".

var pathConfig = {
	"base": "/base/",
	"ignorePrefixes": ["http://", "https://", "mailto:", "#"]
}

var path = new Path(pathConfig);
path.url("http://www.google.com"); // No change
path.url("https://www.gmail.com"); // No change
path.url("mailto:test@example.com"); // No change
path.url("#/example"); // No change

Compatibility

Path.js has been tested in all modern browsers and Internet Explorer 7+.
