Deprecated

Is npm bugging you about this module being deprecated? You are probably depending on this module via the source-map-resolve package, which is deprecated too.

If you are looking for a way to resolve URLs in the browser, use URL.

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 function 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.

Development

Tests

First off, run npm install to install testing modules.

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