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

### <tt>resolveUrl(...urls)</tt>

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`).
