3 URI.js is an [RFC 3986](http://www.ietf.org/rfc/rfc3986.txt) compliant, scheme extendable URI parsing/validating/resolving library for all JavaScript environments (browsers, Node.js, etc).
4 It is also compliant with the IRI ([RFC 3987](http://www.ietf.org/rfc/rfc3987.txt)), IDNA ([RFC 5890](http://www.ietf.org/rfc/rfc5890.txt)), IPv6 Address ([RFC 5952](http://www.ietf.org/rfc/rfc5952.txt)), IPv6 Zone Identifier ([RFC 6874](http://www.ietf.org/rfc/rfc6874.txt)) specifications.
6 URI.js has an extensive test suite, and works in all (Node.js, web) environments. It weighs in at 6.4kb (gzipped, 17kb deflated).
12 URI.parse("uri://user:pass@example.com:123/one/two.three?q1=a1&q2=a2#body");
16 // userinfo : "user:pass",
17 // host : "example.com",
19 // path : "/one/two.three",
20 // query : "q1=a1&q2=a2",
26 URI.serialize({scheme : "http", host : "example.com", fragment : "footer"}) === "http://example.com/#footer"
30 URI.resolve("uri://a/b/c/d?q", "../../g") === "uri://a/g"
34 URI.normalize("HTTP://ABC.com:80/%7Esmith/home.html") === "http://abc.com/~smith/home.html"
38 URI.equal("example://a/b/c/%7Bfoo%7D", "eXAMPLE://a/./b/../b/%63/%7bfoo%7d") === true
43 URI.normalize("//192.068.001.000") === "//192.68.1.0"
46 URI.normalize("//[2001:0:0DB8::0:0001]") === "//[2001:0:db8::1]"
48 //IPv6 zone identifier support
49 URI.parse("//[2001:db8::7%25en1]");
52 // host : "2001:db8::7%en1"
58 URI.serialize(URI.parse("http://examplé.org/rosé")) === "http://xn--exampl-gva.org/ros%C3%A9"
60 URI.serialize(URI.parse("http://xn--exampl-gva.org/ros%C3%A9"), {iri:true}) === "http://examplé.org/rosé"
64 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:
68 Indicates the scheme that the URI should be treated as, overriding the URI's normal scheme parsing behavior.
70 * `reference` (string)
72 If set to `"suffix"`, it indicates that the URI is in the suffix format, and the validator will use the option's `scheme` property to determine the URI's scheme.
74 * `tolerant` (boolean, false)
76 If set to `true`, the parser will relax URI resolving rules.
78 * `absolutePath` (boolean, false)
80 If set to `true`, the serializer will not resolve a relative `path` component.
82 * `iri` (boolean, false)
84 If set to `true`, the serializer will unescape non-ASCII characters as per [RFC 3987](http://www.ietf.org/rfc/rfc3987.txt).
86 * `unicodeSupport` (boolean, false)
88 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).
90 * `domainHost` (boolean, false)
92 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).
96 URI.js supports inserting custom [scheme](http://en.wikipedia.org/wiki/URI_scheme) dependent processing rules. Currently, URI.js has built in support for the following schemes:
98 * http \[[RFC 2616](http://www.ietf.org/rfc/rfc2616.txt)\]
99 * https \[[RFC 2818](http://www.ietf.org/rfc/rfc2818.txt)\]
100 * mailto \[[RFC 6068](http://www.ietf.org/rfc/rfc6068.txt)\]
101 * urn \[[RFC 2141](http://www.ietf.org/rfc/rfc2141.txt)\]
102 * urn:uuid \[[RFC 4122](http://www.ietf.org/rfc/rfc4122.txt)\]
104 ### HTTP/HTTPS Support
106 URI.equal("HTTP://ABC.COM:80", "http://abc.com/") === true
107 URI.equal("https://abc.com", "HTTPS://ABC.COM:443/") === true
111 URI.parse("wss://example.com/foo?bar=baz");
115 // host: "example.com",
116 // resourceName: "/foo?bar=baz",
120 URI.equal("WS://ABC.COM:80/chat#one", "ws://abc.com/chat") === true
124 URI.parse("mailto:alpha@example.com,bravo@example.com?subject=SUBSCRIBE&body=Sign%20me%20up!");
127 // scheme : "mailto",
128 // to : ["alpha@example.com", "bravo@example.com"],
129 // subject : "SUBSCRIBE",
130 // body : "Sign me up!"
135 to : ["alpha@example.com"],
137 body : "Please remove me",
139 cc : "charlie@example.com"
141 }) === "mailto:alpha@example.com?cc=charlie@example.com&subject=REMOVE&body=Please%20remove%20me"
145 URI.parse("urn:example:foo");
153 #### URN UUID Support
155 URI.parse("urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6");
160 // uuid : "f81d4fae-7dec-11d0-a765-00a0c91e6bf6",
165 To load in a browser, use the following tag:
167 <script type="text/javascript" src="uri-js/dist/es5/uri.all.min.js"></script>
169 To load in a CommonJS/Module environment, first install with npm/yarn by running on the command line:
175 Then, in your code, load it using:
177 const URI = require("uri-js");
179 If you are writing your code in ES6+ (ESNEXT) or TypeScript, you would load it using:
181 import * as URI from "uri-js";
183 Or you can load just what you need using named exports:
185 import { parse, serialize, resolve, resolveComponents, normalize, equal, removeDotSegments, pctEncChar, pctDecChars, escapeComponent, unescapeComponent } from "uri-js";
189 ### Breaking changes from 3.x
191 URN parsing has been completely changed to better align with the specification. Scheme is now always `urn`, but has two new properties: `nid` which contains the Namspace Identifier, and `nss` which contains the Namespace Specific String. The `nss` property will be removed by higher order scheme handlers, such as the UUID URN scheme handler.
193 The UUID of a URN can now be found in the `uuid` property.
195 ### Breaking changes from 2.x
197 URI validation has been removed as it was slow, exposed a vulnerabilty, and was generally not useful.
199 ### Breaking changes from 1.x
201 The `errors` array on parsed components is now an `error` string.
