## A JavaScript URI template implementation
|
||
|
|
|
||
|
|
This is a simple URI template implementation following the [RFC 6570 URI Template specification](http://tools.ietf.org/html/rfc6570). The implementation supports all levels defined in the specification and is extensively tested.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
For use with Node.js you can install it through npm:
|
||
|
|
|
||
|
|
$ npm install url-template
|
||
|
|
|
||
|
|
If you want to use it in a browser, copy `lib/url-template.js` into your project and use the global `urltemplate` instance. Alternatively you can use [Bower](http://bower.io/) to install this package:
|
||
|
|
|
||
|
|
$ bower install url-template
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
var template = require('url-template');
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
var emailUrl = template.parse('/{email}/{folder}/{id}');
|
||
|
|
|
||
|
|
// Returns '/user@domain/test/42'
|
||
|
|
emailUrl.expand({
|
||
|
|
email: 'user@domain',
|
||
|
|
folder: 'test',
|
||
|
|
id: 42
|
||
|
|
});
|
||
|
|
|
||
|
|
## A note on error handling and reporting
|
||
|
|
|
||
|
|
The RFC states that errors in the templates could optionally be handled and reported to the user. This implementation takes a slightly different approach in that it 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. The leaves incorrect URLs to be handled by your URL library of choice.
