relateurl

Minify URLs by converting them from absolute to relative.

If you were to use this library on a website like https://example.com/dir1/dir1-1/, you would get results such as:

All string parsing. No directory browsing. It is thoroughly tested, very fast and lightweight with zero external dependencies.

Getting Started

This utility requires Node.js >= 0.10. To install, type this at the command line:

npm install relateurl --save-dev

Options

options.defaultPorts

Type: Object
Default value: {ftp:21, https:80, https:443}

Extend the list with any ports you need. Any URLs containing these default ports will have them removed. Example: https://example.com:80/ will become https://example.com/.

options.directoryIndexes

Type: Array
Default value: ["index.html"]

Extend the list with any resources you need. Works with options.removeDirectoryIndexes.

options.ignore_www

Type: Boolean
Default value: false

This will, for example, consider any domains containing https://www.example.com/ to be related to any that contain https://example.com/.

options.output

Type: constant or String
Choices: RelateUrl.ABSOLUTE,RelateUrl.PATH_RELATIVE,RelateUrl.ROOT_RELATIVE,RelateUrl.SHORTEST
Choices: "absolute","pathRelative","rootRelative","shortest"
Default value: RelateUrl.SHORTEST

RelateUrl.ABSOLUTE will produce an absolute URL. Overrides options.schemeRelative with a value of false.
RelateUrl.PATH_RELATIVE will produce something like ../child-of-parent/etc/.
RelateUrl.ROOT_RELATIVE will produce something like /child-of-root/etc/.
RelateUrl.SHORTEST will choose whichever is shortest between root- and path-relative.

options.rejectedSchemes

Type: Array
Default value: ["data","javascript","mailto"]

Extend the list with any additional schemes. Example: javascript:something will not be modified.

options.removeAuth

Type: Boolean
Default value: false

Remove user authentication information from the output URL.

options.removeDirectoryIndexes

Type: Boolean
Default value: true

Remove any resources that match any found in options.directoryIndexes.

options.removeEmptyQueries

Type: Boolean
Default value: false

Remove empty query variables. Example: https://domain.com/?var1&var2=&var3=asdf will become https://domain.com/?var3=adsf. This does not apply to unrelated URLs (with other protocols, auths, hosts and/or ports).

options.removeRootTrailingSlash

Type: Boolean
Default value: true

Remove trailing slashes from root paths. Example: https://domain.com/?var will become https://domain.com?var while https://domain.com/dir/?var will not be modified.

options.schemeRelative

Type: Boolean
Default value: true

Output URLs relative to the scheme. Example: https://example.com/ will become //example.com/.

options.site

Type: String
Default value: undefined

An options-based version of the from argument. If both are specified, from takes priority.

options.slashesDenoteHost

Type: Boolean
Default value: true

Passed to Node's url.parse.

Examples

This library can be used as a function for single-use or as a class for multiple conversions.

Upon successful conversion, a String will be returned. If an issue is encountered while parsing from, an error will be thrown.

Single Instance

var RelateUrl = require("relateurl");

var result = RelateUrl.relate(from, to, options);

Reusable Instances

var RelateUrl = require("relateurl");

var instance = new RelateUrl(from, options);

var result1 = instance.relate(to1);
var result2 = instance.relate(to2, customOptions);
var result3 = instance.relate(to3);

FAQ

1. Why bother writing/using this?
   To aid in further minifying HTML, mainly for the purpose of faster page loads and SEO. It's been integrated into HTMLMinifier.

2. Why not just use Node's url.parse, url.resolve and path.relative?
   url.parse is used, but url.resolve and path.relative are both slower and less powerful than this library.
