whatwg-url
whatwg-url is a full implementation of the WHATWG URL Standard. It can be used standalone, but it also exposes a lot of the internal algorithms that are useful for integrating a URL parser into a project like jsdom.
Current status
whatwg-url is currently up to date with the URL spec up to commit 6ef17eb.
API
The URL
and URLSearchParams
classes
URL
and URLSearchParams
classesThe main API is provided by the URL
and URLSearchParams
exports, which follows the spec's behavior in all ways (including e.g. USVString
conversion). Most consumers of this library will want to use these.
Low-level URL Standard API
The following methods are exported for use by places like jsdom that need to implement things like HTMLHyperlinkElementUtils
. They mostly operate on or return an "internal URL" or "URL record" type.
URL parser:
parseURL(input, { baseURL, encodingOverride })
Basic URL parser:
basicURLParse(input, { baseURL, encodingOverride, url, stateOverride })
URL serializer:
serializeURL(urlRecord, excludeFragment)
Host serializer:
serializeHost(hostFromURLRecord)
Serialize an integer:
serializeInteger(number)
Origin serializer:
serializeURLOrigin(urlRecord)
Set the username:
setTheUsername(urlRecord, usernameString)
Set the password:
setThePassword(urlRecord, passwordString)
Cannot have a username/password/port:
cannotHaveAUsernamePasswordPort(urlRecord)
Percent decode:
percentDecode(buffer)
The stateOverride
parameter is one of the following strings:
The URL record type has the following API:
path
(as an array)cannotBeABaseURL
(as a boolean)
These properties should be treated with care, as in general changing them will cause the URL record to be in an inconsistent state until the appropriate invocation of basicURLParse
is used to fix it up. You can see examples of this in the URL Standard, where there are many step sequences like "4. Set context object’s url’s fragment to the empty string. 5. Basic URL parse input with context object’s url as url and fragment state as state override." In between those two steps, a URL record is in an unusable state.
The return value of "failure" in the spec is represented by null
. That is, functions like parseURL
and basicURLParse
can return either a URL record or null
.
