调研方向

使用 TypeScript 重现这些错误，并结合 TypeScript 的 lib.dom.d.ts 检查 types/dom/parser.d.ts、types/html/anchor-element.d.ts 和 types/html/document.d.ts 中的声明。比较报告中的继承签名和实现签名，以确定这些类型是否可以与全局 DOM 接口协调一致。完成的标准是，报告的类型错误不再需要 tsc --skipLibCheck。

描述

Hi there,
I'm running into loads of type errors from linkedom when using the library in a typescript project.

These type errors appear to all be either missing properties or incorrect implementations of base class methods (due to parameter types or return types not matching).

The errors are too long to send but I will send a few:

node_modules/linkedom/types/dom/parser.d.ts:12:5 - error TS2416: Property 'parseFromString' in type 'DOMParser' is not assignable to the same property in base type 'DOMParser'.
  Type '<MIME extends "image/svg+xml" | "text/html" | "text/xml">(markupLanguage: string, mimeType: MIME) => { "text/html": HTMLDocument; "image/svg+xml": SVGDocument; "text/xml": XMLDocument; }[MIME]' is not assignable to type '(string: string, type: DOMParserSupportedType) => Document'.
    Type 'HTMLDocument | SVGDocument | XMLDocument' is not assignable to type 'Document'.
      Type 'HTMLDocument' is missing the following properties from type 'Document': URL, alinkColor, anchors, applets, and 181 more.

12     parseFromString<MIME extends keyof {
       ~~~~~~~~~~~~~~~

node_modules/linkedom/types/html/anchor-element.d.ts:4:14 - error TS2420: Class 'import("C:/Users/felis/home/projects/test-linkedom/node_modules/linkedom/types/html/anchor-element").HTMLAnchorElement' incorrectly implements interface 'HTMLAnchorElement'.
  Type 'HTMLAnchorElement' is missing the following properties from type 'HTMLAnchorElement': charset, coords, hreflang, name, and 132 more.

4 export class HTMLAnchorElement extends HTMLElement implements globalThis.HTMLAnchorElement {
               ~~~~~~~~~~~~~~~~~

...

node_modules/linkedom/types/html/document.d.ts:6:9 - error TS2416: Property 'all' in type 'HTMLDocument' is not assignable to the same property in base type 'HTMLDocument'.
  Property 'namedItem' is missing in type 'NodeList' but required in type 'HTMLAllCollection'.

6     get all(): NodeList;
          ~~~

  ../../../AppData/Roaming/npm/node_modules/typescript/lib/lib.dom.d.ts:5953:5
    5953     namedItem(name: string): HTMLCollection | Element | null;
             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    'namedItem' is declared here.

node_modules/linkedom/types/html/document.d.ts:15:9 - error TS2416: Property 'title' in type 'HTMLDocument' is not assignable to the same property in base type 'HTMLDocument'.
  Type 'HTMLTitleElement' is not assignable to type 'string'.

15     set title(arg: HTMLTitleElement);
           ~~~~~

...

Workaround: tsc --skipLibCheck

It'd be great to get the types correct here so --skipLibCheck isn't needed. I would make a PR for this however it seems design decisions would need to be made to fix the types. I'm not sure if the types can be reconciled while still extending / implementing globalThis.DOMParser, globalThis.HTMLElement, /globalThis\.HTML.*Element/, etc.
