URI
A small and fast library for validating, parsing, and resolving URIs (RFC 3986) and IRIs (RFC 3987).
Install
Designed for node.js (ES Modules, TypeScript) and browsers.
npm install @hyperjump/uri
Usage
import { resolveUri, parseUri, isUri, isIri } from "@hyperjump/uri"
const resolved = resolveUri("foo/bar", "http://example.com/aaa/bbb"); // https://example.com/aaa/foo/bar
const components = parseUri("https://[email protected]:80/foo?bar#baz"); // {
// scheme: "https",
// authority: "[email protected]:80",
// userinfo: "jason",
// host: "example.com",
// port: "80",
// path: "/foo",
// query: "bar",
// fragment: "baz"
// }
const a = isUri("http://examplé.org/rosé#"); // false
const a = isIri("http://examplé.org/rosé#"); // true
API
Resolve Relative References
These functions resovle relative-references against a base URI/IRI. The base
URI/IRI must be absolute, meaning it must have a scheme (https
) and no
fragment (#foo
). The resolution process will normalize percent-encoded
characters and dot segments (/.
, /..
).
- resolveUri: (uriReference: string, baseUri: string) => string
- resolveIri: (iriReference: string, baseIri: string) => string
Normalize
These functions apply two normalization rules.
- Decode any unnecessarily percent-encoded characters.
- Convert any lowercase characters in the hex numbers of percent-encoded characters to uppercase.
- Resolve and remove any dot-segments (
/.
,/..
) in paths.
- normalizeUri: (uri: string) => string
- normalizeIri: (iri: string, baseIri: string) => string
URI
A URI is not relative and may include a fragment.
isUri: (value: string) => boolean
parseUri: (value: string) => IdentifierComponents
toAbsoluteUri: (value: string) => string
Takes a URI and strips its fragment component if it exists.
URI-Reference
A URI-reference may be relative.
- isUriReference: (value: string) => boolean
- parseUriReference: (value: string) => IdentifierComponents
absolute-URI
An absolute-URI is not relative an does not include a fragment.
- isAbsoluteUri: (value: string) => boolean
- parseAbsoluteUri: (value: string) => IdentifierComponents
IRI
An IRI is not relative and may include a fragment.
isIri: (value: string) => boolean
parseIri: (value: string) => IdentifierComponents
toAbsoluteIri: (value: string) => string
Takes an IRI and strips its fragment component if it exists.
IRI-reference
An IRI-reference may be relative.
- isIriReference: (value: string) => boolean
- parseIriReference: (value: string) => IdentifierComponents
absolute-IRI
An absolute-IRI is not relative an does not include a fragment.
- isAbsoluteIri: (value: string) => boolean
- parseAbsoluteIri: (value: string) => IdentifierComponents
Types
- IdentifierComponents
- scheme: string
- authority: string
- userinfo: string
- host: string
- port: string
- path: string
- query: string
- fragment: string
