Dependency-free RFC 3986 URI toolbox.
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:
Malformed authorities and out-of-range ports are reported through the parsed component's error field. normalize() leaves malformed string inputs unchanged, and equal() returns false when either string input is malformed.
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.
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.
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"
}
const uri = require('fast-uri')
uri.serialize({scheme: "http", host: "example.com", fragment: "footer"})
// Output
"http://example.com/#footer"
const uri = require('fast-uri')
uri.resolve("uri://a/b/c/d?q", "../../g")
// Output
"uri://a/g"
const uri = require('fast-uri')
uri.normalize('http://example.com/a%2Fb')
// Output
"http://example.com/a%2Fb"
Reserved path escapes such as %2F and %2E are preserved as path data during normalization and comparison.
const uri = require('fast-uri')
uri.equal("example://a/b/c/%7Bfoo%7D", "eXAMPLE://a/./b/../b/%63/%7bfoo%7d")
// Output
true
fast-uri supports inserting custom scheme-dependent processing rules. Currently, fast-uri has built-in support for the following schemes:

The 'url' module is a built-in Node.js module for URL resolution and parsing. It provides similar functionality to fast-uri but is part of the Node.js standard library, making it widely used and supported. However, fast-uri is designed to be faster and more compliant with the latest standards.
The 'whatwg-url' package is a full implementation of the WHATWG URL Standard used by browsers. It offers comprehensive URL parsing and manipulation capabilities similar to fast-uri. While both aim for standard compliance, fast-uri focuses on performance optimization.
The 'uri-js' package provides URI parsing, validation, and manipulation. It supports a wide range of URI operations and is known for its flexibility. Compared to fast-uri, uri-js may offer more features but might not match the performance optimizations of fast-uri.
