Overview

‘URL` — WHATWG-style URL parsing. Public API mirrors the JS class:

u = Dommy::URL.new("https://x.test/a/b?k=v#h")
u.protocol  # "https:"
u.host      # "x.test"
u.pathname  # "/a/b"
u.search    # "?k=v"
u.hash      # "#h"
u.search_params.get("k")  # "v"

Construction with a base URL is supported for relative inputs:

Dommy::URL.new("/a", "https://x.test").href
  # => "https://x.test/a"

Internally backed by Ruby’s URI library — good enough for the common test cases. Edge cases that URI rejects raise ‘DOMException::SyntaxError` (called `TypeError` in JS but Dommy uses the closest WHATWG name).

Class Method Details

.__reset_blob_urls__ ⇒ Object

63
 
# File 'lib/dommy/url.rb', line 61

def __reset_blob_urls__
  @blob_urls.clear
end

.__resolve_blob_url__(url) ⇒ Object

Resolve a blob: URL back to its Blob, or nil if revoked / unknown. Internal — used by fetch / XHR implementations that load blob URLs.

# File 'lib/dommy/url.rb', line 56

def __resolve_blob_url__(url)
  @blob_urls[url.to_s]
end

.create_object_url(blob) ⇒ Object Also known as: createObjectURL

Create a unique blob: URL that resolves back to ‘blob` via `URL.resolve_blob_url(url)`. Returns nil for non-Blob input.

  id = "%032x" % rand(2 ** 128)
  url = "blob:dommy/#{id}"
  @blob_urls[url] = blob
  url
end

.revoke_object_url(url) ⇒ Object Also known as: revokeObjectURL

Revoke a previously-created blob URL. No-op for unknown URLs, matching the spec.
