Dependency free RFC 3986 URI toolbox.
## Usage
## Options
All of the above functions can accept an additional options argument that is an object that can contain one or more of the following properties:
* `scheme` (string)
Indicates the scheme that the URI should be treated as, overriding the URI's normal scheme parsing behavior.
* `reference` (string)
If set to `"suffix"`, it indicates that the URI is in the suffix format and the parser will use the option's `scheme` property to determine the URI's scheme.
* `tolerant` (boolean, false)
If set to `true`, the parser will relax URI resolving rules.
* `absolutePath` (boolean, false)
If set to `true`, the serializer will not resolve a relative `path` component.
* `unicodeSupport` (boolean, false)
If set to `true`, the parser will unescape non-ASCII characters in the parsed output as per [RFC 3987](http://www.ietf.org/rfc/rfc3987.txt).
* `domainHost` (boolean, false)
If set to `true`, the library will treat the `host` component as a domain name, and convert IDNs (International Domain Names) as per [RFC 5891](http://www.ietf.org/rfc/rfc5891.txt).
### Parse
```js
const uri = require('fast-uri')
uri.parse('uri://user:pass@example.com:123/one/two.three?q1=a1&q2=a2#body')
// Output
{
scheme : "uri",
userinfo : "user:pass",
host : "example.com",
port : 123,
path : "/one/two.three",
query : "q1=a1&q2=a2",
fragment : "body"
}
```
### Serialize
```js
const uri = require('fast-uri')
uri.serialize({scheme : "http", host : "example.com", fragment : "footer"})
// Output
"http://example.com/#footer"
```
### Resolve
```js
const uri = require('fast-uri')
uri.resolve("uri://a/b/c/d?q", "../../g")
// Output
"uri://a/g"
```
### Equal
```js
const uri = require('fast-uri')
uri.equal("example://a/b/c/%7Bfoo%7D", "eXAMPLE://a/./b/../b/%63/%7bfoo%7d")
// Output
true
```
## Scheme supports
fast-uri supports inserting custom [scheme](http://en.wikipedia.org/wiki/URI_scheme) dependent processing rules. Currently, fast-uri has built in support for the following schemes:
* http \[[RFC 2616](http://www.ietf.org/rfc/rfc2616.txt)\]
* https \[[RFC 2818](http://www.ietf.org/rfc/rfc2818.txt)\]
* ws \[[RFC 6455](http://www.ietf.org/rfc/rfc6455.txt)\]
* wss \[[RFC 6455](http://www.ietf.org/rfc/rfc6455.txt)\]
* urn \[[RFC 2141](http://www.ietf.org/rfc/rfc2141.txt)\]
* urn:uuid \[[RFC 4122](http://www.ietf.org/rfc/rfc4122.txt)\]
