URI Template Lite – [![Coverage][1]][2] [![size][3]][4] [![Buy Me A Tea][5]][6]
=================

URI Template [RFC 6570][] expansion and extraction.


Usage
-----

`npm install uri-template-lite`

```javascript
var UriTemplate = require("uri-template-lite")

// Call `expand` directly
var data = {"domain":"example.com", "user":"fred", "query":"mycelium"}
UriTemplate.expand("http://{domain}/~{user}/foo{?query,number}", data)
// Returns http://example.com/~fred/foo?query=mycelium

// ..or use `Template` constructor
var template = new UriTemplate("http://{domain}/~{user}/foo{?query,number}")
template.expand({"domain":"example.com", "user":"fred", "query":"mycelium", "number": 3})
// Returns http://example.com/~fred/foo?query=mycelium&number=3

// Extract variables
template.match("http://example.com/~fred/foo?query=mycelium&number=3")
// Returns {"domain":"example.com", "user":"fred", "query":"mycelium", "number": "3"}

template.match("http://other.com/?query=mycelium")
// Returns null
```



About error handling
--------------------

This implementation tries to do a best effort template expansion
and leaves erroneous expressions in the returned URI
instead of throwing errors.
So for example, the incorrect expression
{unclosed will return {unclosed as output.



Browser Support
---------------

It should work IE6 and up but automated testing is currently broken.

-   For older browsers it requires `browser-upgrade-lite` package
    or other ES5 polyfill.
-   FF3-4 `escape` should be patched to remove non-standard 2nd param,
    `browser-upgrade-lite` does that.
