blocks|key|340280|text|在旧版本的类型定义文件(v0.14)中，接口只是在全局React命名空间下声明的，因此以前可以使用标准的合并语法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|340281|declare+namespace+React+{

}|code-block|syntax|javascript|340282|但是，新版本的d.ts文件(v15.0)已经声明了模块中的所有内容。由于模块不支持合并，据我所知，现在唯一的选择似乎是module+augmentation：https://www.typescriptlang.org/docs/handbook/declaration-merging.html。|offset|length|style|CODE|340283|我做了以下实验，它对我有效：|340284|import+*+as+React+from+'react';

Looks like in older versions of type definition files (v0.14) the interfaces were simply declared under a global React namespace, so previously you could use the standard merging syntax.

<pre><code>declare namespace React {

 interface HTMLProps&lt;T&gt; extends HTMLAttributes, ClassAttributes&lt;T&gt; {
 }
}
</code></pre>

However the new version of d.ts file (v15.0) have declared everything inside a module. Since modules do not support merging, to the best of my knowledge the only option right now seems to be <code>module augmentation</code>:
<a href="https://www.typescriptlang.org/docs/handbook/declaration-merging.html" rel="noreferrer">https://www.typescriptlang.org/docs/handbook/declaration-merging.html</a>

I did the following experiment and it worked for me:

<pre><code>import * as React from 'react';

declare module 'react' {
 interface HTMLProps&lt;T&gt; {
 block?:string;
 element?:string;
 modifiers?:string;
 }

}

export const Foo = () =&gt; {

 return (
 &lt;div block="123" element="456"&gt;
 &lt;/div&gt;
 )
};
</code></pre>

Obviously this is quite tedious, you could put the augmentation code in another file as shown in the example from the typescript handbook, and import it:

<pre><code>import * as React from 'react';
import './react_augmented';
</code></pre>

But it's still quite dirty. So maybe it's best to address the issue with the contributors of the type definition file.

I wanted to use glamor's <a href="https://github.com/threepointone/glamor/blob/master/docs/createElement.md" rel="noreferrer">createElement</a> replacement which adds a <code>css</code> prop to every element.

To add to the accepted answer, module augmentation seems to do the trick but <code>HTMLProps</code> only worked for non-input elements. The correct interfaces to extend seems to be <code>HTMLAttributes</code> and <code>SVGAttributes</code>. 

<pre><code>declare module 'react' {
 interface HTMLAttributes&lt;T&gt; {
 css?: any
 }

 interface SVGAttributes&lt;T&gt; {
 css?: any
 }
}
</code></pre>

To avoid importing the module augmentation in every component, re-export createElement:

<pre><code>// createElement.ts
import { createElement } from 'glamor/react'

declare module 'react' {
 interface HTMLAttributes&lt;T&gt; {
 css?: any
 }

 interface SVGAttributes&lt;T&gt; {
 css?: any
 }
}

export default createElement
</code></pre>

Then tell TS to use our <code>createElement</code> for JSX with this tsconfig:

<pre><code>{
 "compilerOptions": {
 "jsx": "react",
 "jsxFactory": "createElement"
 }
}
</code></pre>

Usage:

<pre><code>// MyComponent.tsx
import createElement from './createElement'

export default function MyComponent() {
 return &lt;div css={{ color: 'red' }} /&gt;
}
</code></pre>

An up-to-date example (May 2019)

React type definition file (by default - <code>index.d.ts</code> when staring with <code>create-react-app</code>) contain list of all the standard HTML elements, as well as known attributes.

In order to allow custom HTML attributes, you need to define it's typing.
Do that by expanding <code>HTMLAttributes</code> interface:

<pre><code>declare module 'react' {
 interface HTMLAttributes&lt;T&gt; extends AriaAttributes, DOMAttributes&lt;T&gt; {
 // extends React's HTMLAttributes
 custom?: string;
 }
}
</code></pre>

I needed to add module global for Vue 3 *.vue files to work and explicitly add react types in package.json devDependencies as such &quot;@types/react&quot;: &quot;^18.0.14&quot;.
<pre><code>// src/html.d.ts

declare global {

 dataCy?: string;
 class?: string | string[] | Record&lt;string, boolean&gt; | Record&lt;string, boolean&gt;[];
 }
 }
}
</code></pre>

Anyone know how to properly add/extend all native HTML element attributes with custom ones?

With <a href="http://www.typescriptlang.org/docs/handbook/declaration-merging.html#merging-interfaces" rel="noreferrer">the TypeScript documentation for merging interfaces</a>, I thought that I could just do this:

<pre><code>interface HTMLElement {
 block?: BEM.Block;
 element?: BEM.Element;
 modifiers?: BEM.Modifiers;
}

&lt;div block="foo" /&gt;; // error
</code></pre>

But I get the following Intellisense error in vscode 1.6.1 (latest):

<blockquote>
 [ts] Property 'block' does not exist on type 'HTMLProps'.
</blockquote>

The <code>HTMLProps</code> to which they are referring is <code>React.HTMLProps&lt;T&gt;</code> and the <code>div</code> element is declared to use it like so:

<pre><code>namespace JSX {
 interface IntrinsicElements {
 div: React.HTMLProps&lt;HTMLDivElement&gt;
 }
}
</code></pre>

I tried redeclaring the <code>div</code>, but to no avail.

Related: <a href="https://github.com/Microsoft/TypeScript/issues/11684" rel="noreferrer">https://github.com/Microsoft/TypeScript/issues/11684</a>

Edit: Here's what ended up working for me:

<pre><code>declare module 'react' {
 interface HTMLAttributes&lt;T&gt; extends DOMAttributes&lt;T&gt; {
 block?: string
 element?: string
 modifiers?: Modifiers // &lt;-- custom interface
 }
}
</code></pre>

How do I add attributes to existing HTML elements in TypeScript/JSX?
