35Installation
36============
37
38- `npm install resolve-url`
39- `bower install resolve-url`
40- `component install lydell/resolve-url`
41
42Works with CommonJS, AMD and browser globals, through UMD.

45Usage
46=====
47
48### `resolveUrl(...urls)` ###
49
50Pass one or more urls. Resolves the last one to an absolute url, using the
51previous ones and `window.location`.
52
53It’s like starting out on `window.location`, and then clicking links with the
54urls as `href` attributes in order, from left to right.
55
56Unlike Node.js’ [`path.resolve`], this function always goes through all of the
57arguments, from left to right. `path.resolve` goes from right to left and only
58in the worst case goes through them all. Should that matter.
59
60Actually, the function is _really_ like clicking a lot of links in series: An
61actual `<a>` gets its `href` attribute set for each url! This means that the
62url resolution of the browser is used, which makes this module really
63light-weight.
64
65Also note that this functions deals with urls, not paths, so in that respect it
66has more in common with Node.js’ [`url.resolve`]. But the arguments are more
67like [`path.resolve`].

69[`path.resolve`]: http://nodejs.org/api/path.html#path_path_resolve_from_to
70[`url.resolve`]: http://nodejs.org/api/url.html#url_url_resolve_from_to
71
72
73Tests
74=====
75
76Run `npm test`, which lints the code and then gives you a link to open in a
77browser of choice (using `testling`).
