url

The node:url module provides utilities for URL resolution and parsing. It can be accessed using:

import url from 'node:url';

Usage in Deno

import * as mod from "node:url";

class URL

Usage in Deno

import { URL } from "node:url";

Browser-compatible URL class, implemented by following the WHATWG URL Standard. Examples of parsed URLs may be found in the Standard itself. The URL class is also available on the global object.

In accordance with browser conventions, all properties of URL objects are implemented as getters and setters on the class prototype, rather than as data properties on the object itself. Thus, unlike legacy urlObjects, using the delete keyword on any properties of URL objects (e.g. delete myURL.protocol, delete myURL.pathname, etc) has no effect but will still return true.

Constructors

URL(
input: string | { toString: () => string; },
base?: string | URL,
)
new

Properties

hash: string

Gets and sets the fragment portion of the URL.

const myURL = new URL('https://example.org/foo#bar');
console.log(myURL.hash);
// Prints #bar

myURL.hash = 'baz';
console.log(myURL.href);
// Prints https://example.org/foo#baz

Invalid URL characters included in the value assigned to the hash property are percent-encoded. The selection of which characters to percent-encode may vary somewhat from what the parse and format methods would produce.

host: string

Gets and sets the host portion of the URL.

const myURL = new URL('https://example.org:81/foo');
console.log(myURL.host);
// Prints example.org:81

myURL.host = 'example.com:82';
console.log(myURL.href);
// Prints https://example.com:82/foo

Invalid host values assigned to the host property are ignored.

hostname: string

Gets and sets the host name portion of the URL. The key difference betweenurl.host and url.hostname is that url.hostname does not include the port.

const myURL = new URL('https://example.org:81/foo');
console.log(myURL.hostname);
// Prints example.org

// Setting the hostname does not change the port
myURL.hostname = 'example.com';
console.log(myURL.href);
// Prints https://example.com:81/foo

// Use myURL.host to change the hostname and port
myURL.host = 'example.org:82';
console.log(myURL.href);
// Prints https://example.org:82/foo

Invalid host name values assigned to the hostname property are ignored.

href: string

Gets and sets the serialized URL.

const myURL = new URL('https://example.org/foo');
console.log(myURL.href);
// Prints https://example.org/foo

myURL.href = 'https://example.com/bar';
console.log(myURL.href);
// Prints https://example.com/bar

Getting the value of the href property is equivalent to calling toString.

Setting the value of this property to a new value is equivalent to creating a new URL object using new URL(value). Each of the URL object's properties will be modified.

If the value assigned to the href property is not a valid URL, a TypeError will be thrown.

origin: string
readonly

Gets the read-only serialization of the URL's origin.

const myURL = new URL('https://example.org/foo/bar?baz');
console.log(myURL.origin);
// Prints https://example.org

const idnURL = new URL('https://測試');
console.log(idnURL.origin);
// Prints https://xn--g6w251d

console.log(idnURL.hostname);
// Prints xn--g6w251d
password: string

Gets and sets the password portion of the URL.

const myURL = new URL('https://abc:xyz@example.com');
console.log(myURL.password);
// Prints xyz

myURL.password = '123';
console.log(myURL.href);
// Prints https://abc:123@example.com/

Invalid URL characters included in the value assigned to the password property are percent-encoded. The selection of which characters to percent-encode may vary somewhat from what the parse and format methods would produce.

pathname: string

Gets and sets the path portion of the URL.

const myURL = new URL('https://example.org/abc/xyz?123');
console.log(myURL.pathname);
// Prints /abc/xyz

myURL.pathname = '/abcdef';
console.log(myURL.href);
// Prints https://example.org/abcdef?123

Invalid URL characters included in the value assigned to the pathname property are percent-encoded. The selection of which characters to percent-encode may vary somewhat from what the parse and format methods would produce.

port: string

Gets and sets the port portion of the URL.

The port value may be a number or a string containing a number in the range 0 to 65535 (inclusive). Setting the value to the default port of the URL objects given protocol will result in the port value becoming the empty string ('').

The port value can be an empty string in which case the port depends on the protocol/scheme:

Upon assigning a value to the port, the value will first be converted to a string using .toString().

If that string is invalid but it begins with a number, the leading number is assigned to port. If the number lies outside the range denoted above, it is ignored.

const myURL = new URL('https://example.org:8888');
console.log(myURL.port);
// Prints 8888

// Default ports are automatically transformed to the empty string
// (HTTPS protocol's default port is 443)
myURL.port = '443';
console.log(myURL.port);
// Prints the empty string
console.log(myURL.href);
// Prints https://example.org/

myURL.port = 1234;
console.log(myURL.port);
// Prints 1234
console.log(myURL.href);
// Prints https://example.org:1234/

// Completely invalid port strings are ignored
myURL.port = 'abcd';
console.log(myURL.port);
// Prints 1234

// Leading numbers are treated as a port number
myURL.port = '5678abcd';
console.log(myURL.port);
// Prints 5678

// Non-integers are truncated
myURL.port = 1234.5678;
console.log(myURL.port);
// Prints 1234

// Out-of-range numbers which are not represented in scientific notation
// will be ignored.
myURL.port = 1e10; // 10000000000, will be range-checked as described below
console.log(myURL.port);
// Prints 1234

Numbers which contain a decimal point, such as floating-point numbers or numbers in scientific notation, are not an exception to this rule. Leading numbers up to the decimal point will be set as the URL's port, assuming they are valid:

myURL.port = 4.567e21;
console.log(myURL.port);
// Prints 4 (because it is the leading number in the string '4.567e21')
protocol: string

Gets and sets the protocol portion of the URL.

const myURL = new URL('https://example.org');
console.log(myURL.protocol);
// Prints https:

myURL.protocol = 'ftp';
console.log(myURL.href);
// Prints ftp://example.org/

Invalid URL protocol values assigned to the protocol property are ignored.

search: string

Gets and sets the serialized query portion of the URL.

const myURL = new URL('https://example.org/abc?123');
console.log(myURL.search);
// Prints ?123

myURL.search = 'abc=xyz';
console.log(myURL.href);
// Prints https://example.org/abc?abc=xyz

Any invalid URL characters appearing in the value assigned the search property will be percent-encoded. The selection of which characters to percent-encode may vary somewhat from what the parse and format methods would produce.

searchParams: URLSearchParams
readonly

Gets the URLSearchParams object representing the query parameters of the URL. This property is read-only but the URLSearchParams object it provides can be used to mutate the URL instance; to replace the entirety of query parameters of the URL, use the search setter. See URLSearchParams documentation for details.

Use care when using .searchParams to modify the URL because, per the WHATWG specification, the URLSearchParams object uses different rules to determine which characters to percent-encode. For instance, the URL object will not percent encode the ASCII tilde (~) character, while URLSearchParams will always encode it:

const myURL = new URL('https://example.org/abc?foo=~bar');

console.log(myURL.search);  // prints ?foo=~bar

// Modify the URL via searchParams...
myURL.searchParams.sort();

console.log(myURL.search);  // prints ?foo=%7Ebar
username: string

Gets and sets the username portion of the URL.

const myURL = new URL('https://abc:xyz@example.com');
console.log(myURL.username);
// Prints abc

myURL.username = '123';
console.log(myURL.href);
// Prints https://123:xyz@example.com/

Any invalid URL characters appearing in the value assigned the username property will be percent-encoded. The selection of which characters to percent-encode may vary somewhat from what the parse and format methods would produce.

Methods

toJSON(): string

The toJSON() method on the URL object returns the serialized URL. The value returned is equivalent to that of href and toString.

This method is automatically called when an URL object is serialized with JSON.stringify().

const myURLs = [
  new URL('https://www.example.com'),
  new URL('https://test.example.org'),
];
console.log(JSON.stringify(myURLs));
// Prints ["https://www.example.com/","https://test.example.org/"]
toString(): string

The toString() method on the URL object returns the serialized URL. The value returned is equivalent to that of href and toJSON.

Static Methods

canParse(
input: string,
base?: string,
): boolean

Checks if an input relative to the base can be parsed to a URL.

const isValid = URL.canParse('/foo', 'https://example.org/'); // true

const isNotValid = URL.canParse('/foo'); // false
createObjectURL(blob: NodeBlob): string

Creates a 'blob:nodedata:...' URL string that represents the given Blob object and can be used to retrieve the Blob later.

import {
  Blob,
  resolveObjectURL,
} from 'node:buffer';

const blob = new Blob(['hello']);
const id = URL.createObjectURL(blob);

// later...

const otherBlob = resolveObjectURL(id);
console.log(otherBlob.size);

The data stored by the registered Blob will be retained in memory until URL.revokeObjectURL() is called to remove it.

Blob objects are registered within the current thread. If using Worker Threads, Blob objects registered within one Worker will not be available to other workers or the main thread.

parse(
input: string,
base?: string,
): URL | null

Parses a string as a URL. If base is provided, it will be used as the base URL for the purpose of resolving non-absolute input URLs. Returns null if input is not a valid.

revokeObjectURL(id: string): void

Removes the stored Blob identified by the given ID. Attempting to revoke a ID that isn't registered will silently fail.

interface URL

extends _URL

variable URL

URL class is a global reference for import { URL } from 'url' https://nodejs.org/api/url.html#the-whatwg-url-api

Type

globalThis extends { onmessage: any; URL: infer T; } ? T : _URL

class URLSearchParams

implements Iterable<[string, string]>

Usage in Deno

import { URLSearchParams } from "node:url";

The URLSearchParams API provides read and write access to the query of a URL. The URLSearchParams class can also be used standalone with one of the four following constructors. The URLSearchParams class is also available on the global object.

The WHATWG URLSearchParams interface and the querystring module have similar purpose, but the purpose of the querystring module is more general, as it allows the customization of delimiter characters (&#x26; and =). On the other hand, this API is designed purely for URL query strings.

const myURL = new URL('https://example.org/?abc=123');
console.log(myURL.searchParams.get('abc'));
// Prints 123

myURL.searchParams.append('abc', 'xyz');
console.log(myURL.href);
// Prints https://example.org/?abc=123&#x26;abc=xyz

myURL.searchParams.delete('abc');
myURL.searchParams.set('a', 'b');
console.log(myURL.href);
// Prints https://example.org/?a=b

const newSearchParams = new URLSearchParams(myURL.searchParams);
// The above is equivalent to
// const newSearchParams = new URLSearchParams(myURL.search);

newSearchParams.append('a', 'c');
console.log(myURL.href);
// Prints https://example.org/?a=b
console.log(newSearchParams.toString());
// Prints a=b&#x26;a=c

// newSearchParams.toString() is implicitly called
myURL.search = newSearchParams;
console.log(myURL.href);
// Prints https://example.org/?a=b&#x26;a=c
newSearchParams.delete('a');
console.log(myURL.href);
// Prints https://example.org/?a=b&#x26;a=c

Constructors

URLSearchParams(init?:
URLSearchParams
| string
| Record<string, string | readonly string[]>
| Iterable<[string, string]>
| ReadonlyArray<[string, string]>
)
new

Properties

size: number
readonly

The total number of parameter entries.

Methods

[Symbol.iterator](): URLSearchParamsIterator<[string, string]>
append(
name: string,
value: string,
): void

Append a new name-value pair to the query string.

delete(
name: string,
value?: string,
): void

If value is provided, removes all name-value pairs where name is name and value is value.

If value is not provided, removes all name-value pairs whose name is name.

entries(): URLSearchParamsIterator<[string, string]>

Returns an ES6 Iterator over each of the name-value pairs in the query. Each item of the iterator is a JavaScript Array. The first item of the Array is the name, the second item of the Array is the value.

Alias for urlSearchParams[@@iterator]().

forEach<TThis = this>(
fn: (
this: TThis,
value: string,
name: string,
searchParams: URLSearchParams,
) => void,
thisArg?: TThis,
): void

Iterates over each name-value pair in the query and invokes the given function.

const myURL = new URL('https://example.org/?a=b&#x26;c=d');
myURL.searchParams.forEach((value, name, searchParams) => {
  console.log(name, value, myURL.searchParams === searchParams);
});
// Prints:
//   a b true
//   c d true
get(name: string): string | null

Returns the value of the first name-value pair whose name is name. If there are no such pairs, null is returned.

getAll(name: string): string[]

Returns the values of all name-value pairs whose name is name. If there are no such pairs, an empty array is returned.

has(
name: string,
value?: string,
): boolean

Checks if the URLSearchParams object contains key-value pair(s) based on name and an optional value argument.

If value is provided, returns true when name-value pair with same name and value exists.

If value is not provided, returns true if there is at least one name-value pair whose name is name.

keys(): URLSearchParamsIterator<string>

Returns an ES6 Iterator over the names of each name-value pair.

const params = new URLSearchParams('foo=bar&#x26;foo=baz');
for (const name of params.keys()) {
  console.log(name);
}
// Prints:
//   foo
//   foo
set(
name: string,
value: string,
): void

Sets the value in the URLSearchParams object associated with name to value. If there are any pre-existing name-value pairs whose names are name, set the first such pair's value to value and remove all others. If not, append the name-value pair to the query string.

const params = new URLSearchParams();
params.append('foo', 'bar');
params.append('foo', 'baz');
params.append('abc', 'def');
console.log(params.toString());
// Prints foo=bar&#x26;foo=baz&#x26;abc=def

params.set('foo', 'def');
params.set('xyz', 'opq');
console.log(params.toString());
// Prints foo=def&#x26;abc=def&#x26;xyz=opq
sort(): void

Sort all existing name-value pairs in-place by their names. Sorting is done with a stable sorting algorithm, so relative order between name-value pairs with the same name is preserved.

This method can be used, in particular, to increase cache hits.

const params = new URLSearchParams('query[]=abc&#x26;type=search&#x26;query[]=123');
params.sort();
console.log(params.toString());
// Prints query%5B%5D=abc&#x26;query%5B%5D=123&#x26;type=search
toString(): string

Returns the search parameters serialized as a string, with characters percent-encoded where necessary.

values(): URLSearchParamsIterator<string>

Returns an ES6 Iterator over the values of each name-value pair.

function format

Usage in Deno

import { format } from "node:url";

Overload 1

format(
urlObject: URL,
options?: URLFormatOptions,
): string

The url.format() method returns a formatted URL string derived from urlObject.

import url from 'node:url';
url.format({
  protocol: 'https',
  hostname: 'example.com',
  pathname: '/some/path',
  query: {
    page: 1,
    format: 'json',
  },
});

// => 'https://example.com/some/path?page=1&#x26;format=json'

If urlObject is not an object or a string, url.format() will throw a TypeError.

The formatting process operates as follows:

  • A new empty string result is created.
  • If urlObject.protocol is a string, it is appended as-is to result.
  • Otherwise, if urlObject.protocol is not undefined and is not a string, an Error is thrown.
  • For all string values of urlObject.protocol that do not end with an ASCII colon (:) character, the literal string : will be appended to result.
  • If either of the following conditions is true, then the literal string // will be appended to result:
    • urlObject.slashes property is true;
    • urlObject.protocol begins with http, https, ftp, gopher, or file;
  • If the value of the urlObject.auth property is truthy, and either urlObject.host or urlObject.hostname are not undefined, the value of urlObject.auth will be coerced into a string and appended to result followed by the literal string @.
  • If the urlObject.host property is undefined then:
    • If the urlObject.hostname is a string, it is appended to result.
    • Otherwise, if urlObject.hostname is not undefined and is not a string, an Error is thrown.
    • If the urlObject.port property value is truthy, and urlObject.hostname is not undefined: * The literal string : is appended to result, and * The value of urlObject.port is coerced to a string and appended to result.
  • Otherwise, if the urlObject.host property value is truthy, the value of urlObject.host is coerced to a string and appended to result.
  • If the urlObject.pathname property is a string that is not an empty string:
    • If the urlObject.pathname does not start with an ASCII forward slash (/), then the literal string '/' is appended to result.
    • The value of urlObject.pathname is appended to result.
  • Otherwise, if urlObject.pathname is not undefined and is not a string, an Error is thrown.
  • If the urlObject.search property is undefined and if the urlObject.queryproperty is an Object, the literal string ? is appended to result followed by the output of calling the querystring module's stringify() method passing the value of urlObject.query.
  • Otherwise, if urlObject.search is a string:
    • If the value of urlObject.search does not start with the ASCII question mark (?) character, the literal string ? is appended to result.
    • The value of urlObject.search is appended to result.
  • Otherwise, if urlObject.search is not undefined and is not a string, an Error is thrown.
  • If the urlObject.hash property is a string:
    • If the value of urlObject.hash does not start with the ASCII hash (#) character, the literal string # is appended to result.
    • The value of urlObject.hash is appended to result.
  • Otherwise, if the urlObject.hash property is not undefined and is not a string, an Error is thrown.
  • result is returned.

Parameters

urlObject: UrlObject | string

A URL object (as returned by url.parse() or constructed otherwise). If a string, it is converted to an object by passing it to url.parse().

Return Type

string

function parse

Usage in Deno

import { parse } from "node:url";

Overload 1

parse(urlString: string): UrlWithStringQuery
Deprecated

The url.parse() method takes a URL string, parses it, and returns a URL object.

A TypeError is thrown if urlString is not a string.

A URIError is thrown if the auth property is present but cannot be decoded.

url.parse() uses a lenient, non-standard algorithm for parsing URL strings. It is prone to security issues such as host name spoofing and incorrect handling of usernames and passwords. Do not use with untrusted input. CVEs are not issued for url.parse() vulnerabilities. Use the WHATWG URL API instead.

Parameters

urlString: string

The URL string to parse.

Return Type

UrlWithStringQuery

Overload 2

parse(
urlString: string,
parseQueryString: false | undefined,
slashesDenoteHost?: boolean,

function pathToFileURL

Usage in Deno

import { pathToFileURL } from "node:url";
pathToFileURL(
path: string,
options?: PathToFileUrlOptions,
): URL

This function ensures that path is resolved absolutely, and that the URL control characters are correctly encoded when converting into a File URL.

import { pathToFileURL } from 'node:url';

new URL('/foo#1', 'file:');           // Incorrect: file:///foo#1
pathToFileURL('/foo#1');              // Correct:   file:///foo%231 (POSIX)

new URL('/some/path%.c', 'file:');    // Incorrect: file:///some/path%.c
pathToFileURL('/some/path%.c');       // Correct:   file:///some/path%25.c (POSIX)

Parameters

path: string

The path to convert to a File URL.

options: PathToFileUrlOptions
optional

Return Type

URL

The file URL object.

function resolve

Usage in Deno

import { resolve } from "node:url";
resolve(
from: string,
to: string,
): string

The url.resolve() method resolves a target URL relative to a base URL in a manner similar to that of a web browser resolving an anchor tag.

import url from 'node:url';
url.resolve('/one/two/three', 'four');         // '/one/two/four'
url.resolve('http://example.com/', '/one');    // 'http://example.com/one'
url.resolve('http://example.com/one', '/two'); // 'http://example.com/two'

To achieve the same result using the WHATWG URL API:

function resolve(from, to) {
  const resolvedUrl = new URL(to, new URL(from, 'resolve://'));
  if (resolvedUrl.protocol === 'resolve:') {
    // `from` is a relative URL.
    const { pathname, search, hash } = resolvedUrl;
    return pathname + search + hash;
  }
  return resolvedUrl.toString();
}

resolve('/one/two/three', 'four');         // '/one/two/four'
resolve('http://example.com/', '/one');    // 'http://example.com/one'
resolve('http://example.com/one', '/two'); // 'http://example.com/two'

Parameters

from: string

The base URL to use if to is a relative URL.

to: string

The target URL to resolve.

Return Type

string
