Overview

Like Node.js’ path.resolve/url.resolve for the browser.

var resolveUrl = require("resolve-url")

window.location
// https://example.com/articles/resolving-urls/edit

resolveUrl("remove")
// https://example.com/articles/resolving-urls/remove

resolveUrl("/static/scripts/app.js")
// https://example.com/static/scripts/app.js

// Imagine /static/scripts/app.js contains `//# sourceMappingURL=../source-maps/app.js.map`
resolveUrl("/static/scripts/app.js", "../source-maps/app.js.map")
// https://example.com/static/source-maps/app.js.map

resolveUrl("/static/scripts/app.js", "../source-maps/app.js.map", "../coffee/app.coffee")
// https://example.com/static/coffee/app.coffee

resolveUrl("//cdn.example.com/jquery.js")
// https://cdn.example.com/jquery.js

resolveUrl("http://foo.org/")
// http://foo.org/

Installation

npm install resolve-url
bower install resolve-url
component install lydell/resolve-url

Works with CommonJS, AMD and browser globals, through UMD.

Usage

`resolveUrl(...urls)`

Pass one or more urls. Resolves the last one to an absolute url, using the previous ones and window.location.

It’s like starting out on window.location, and then clicking links with the urls as href attributes in order, from left to right.

Unlike Node.js’ path.resolve, this function always goes through all of the arguments, from left to right. path.resolve goes from right to left and only in the worst case goes through them all. Should that matter.

Actually, the function is really like clicking a lot of links in series: An actual <a> gets its href attribute set for each url! This means that the url resolution of the browser is used, which makes this module really light-weight.

Also note that this functions deals with urls, not paths, so in that respect it has more in common with Node.js’ url.resolve. But the arguments are more like path.resolve.

Tests

Run npm test, which lints the code and then gives you a link to open in a browser of choice (using testling).
