 ## Introduction
-You can build your own extensions from scratch. Extend the provided `Node`, `Mark`, and `Extension` classes and pass an object with your configuration and custom code.
+One of the strength of tiptap is it’s extendability. You don’t depend on the provided extensions, it’s intended to extend the editor to your liking. With custom extensions you can add new content types and new functionalities, on top of what already exists or from scratch.
 
-Read the [overwrite & extend](/guide/extend-extensions) guide to learn more about all the things you can control.
+## Extend existing extensions
+Let’s say you want to change the keyboard shortcuts for the bullet list. You should start by looking at [the source code of the `BulletList` extension](https://github.com/ueberdosis/tiptap/blob/main/packages/extension-bullet-list/src/bullet-list.ts) and find the part you would like to change. In that case, the keyboard shortcut, and just that.
+
+Every extension has an `extend()` method, which takes an object with everything you want to change or add to it. For the bespoken example, your code could like that:
+
+```js
+// 1. Import the extension
+import BulletList from '@tiptap/extension-bullet-list'
+
+// 2. Overwrite the keyboard shortcuts
+const CustomBulletList = BulletList.extend({
+  addKeyboardShortcuts() {
+    return {
+      'Mod-l': () => this.editor.commands.toggleBulletList(),
+    }
+  },
+})
+
+// 3. Add the custom extension to your editor
+new Editor({
+  extensions: [
+    CustomBulletList(),
+    // …
+  ],
+})
+```
+
+The same applies to every aspect of an existing extension, except to the name. Let’s look at all the things that you can change through the extend method. We focus on one aspect in every example, but you can combine all those examples and change multiple aspects in one `extend()` call too.
+
+### Name
+The extension name is used in a whole lot of places and changing it isn’t too easy. If you want to change the name of an existing extension, we would recommended to copy the whole extension and change the name in all occurrences.
+
+The extension name is also part of the JSON. If you [store your content as JSON](/guide/output#option-1-json), you need to change the name there too.
+
+### Priority
+The priority defines the order in which extensions are registered. The default priority is `100`, that’s what most extension have. Extensions with a higher priority will be loaded earlier.
+
+```js
+import Link from '@tiptap/extension-link'
+
+const CustomLink = Link.extend({
+  priority: 1000,
+})
+```
+
+The order in which extensions are loaded influences two things:
+
+1. #### Plugin order
+   Plugins of extensions with a higher priority will run first.
+
+2. #### Schema order
+   The [`Link`](/api/marks/link) mark for example has a higher priority, which means it’ll be rendered as `<a href="…"><strong>Example</strong></a>` instead of `<strong><a href="…">Example</></strong>`.
+
+### Settings
+All settings can be configured through the extension anyway, but if you want to change the default settings, for example to provide a library on top of tiptap for other developers, you can do it like that:
+
+```js
+import Heading from '@tiptap/extension-heading'
+
+const CustomHeading = Heading.extend({
+  defaultOptions: {
+    ...Heading.options,
+    levels: [1, 2, 3],
+  },
+})
+```
+
+### Schema
+tiptap works with a strict schema, which configures how the content can be structured, nested, how it behaves and many more things. You [can change all aspects of the schema](/api/schema) for existing extensions. Let’s walk through a few common use cases.
+
+The default `Blockquote` extension can wrap other nodes, like headings. If you want to allow nothing but paragraphs in your blockquotes, this is how you could achieve it:
+
+```js
+// Blockquotes must only include paragraphs
+import Blockquote from '@tiptap/extension-blockquote'
+
+const CustomBlockquote = Blockquote.extend({
+  content: 'paragraph*',
+})
+```
+
+The schema even allows to make your nodes draggable, that’s what the `draggable` option is for, which defaults to `false`.
+
+```js
+// Draggable paragraphs
+import Paragraph from '@tiptap/extension-paragraph'
+
+const CustomParagraph = Paragraph.extend({
+  draggable: true,
+})
+```
+
+That’s just two tiny examples, but [the underlying ProseMirror schema](https://prosemirror.net/docs/ref/#model.SchemaSpec) is really powerful. You should definitely read the documentation to understand all the nifty details.
+
+### Attributes
+You can use attributes to store additional information in the content. Let’s say you want to extend the default paragraph extension to enable paragraphs to have different colors:
+
+```js
+const CustomParagraph = Paragraph.extend({
+  addAttributes() {
+    // Return an object with attribute configuration
+    return {
+      color: {
+        default: 'pink',
+      },
+    },
+  },
+})
+
+// Result:
+// <p color="pink">Example Text</p>
+```
+
+That’s already enough to tell tiptap about the new attribute, and set `'pink'` as the default value. All attributes will be rendered as a HTML attribute by default, and parsed as attributes from the content.
+
+Let’s stick with the color example and assume you’ll want to add an inline style to actually color the text. With the `renderHTML` function you can return HTML attributes which will be rendered in the output.
+
+This examples adds a style HTML attribute based on the value of color:
+
+```js
+const CustomParagraph = Paragraph.extend({
+  addAttributes() {
+    return {
+      color: {
+        default: null,
+        // Take the attribute values
+        renderHTML: attributes => {
+          // … and return an object with HTML attributes.
+          return {
+            style: `color: ${attributes.color}`,
+          }
+        },
+      },
+    }
+  },
+})
+
+// Result:
+// <p style="color: pink">Example Text</p>
+```
+
+You can also control how the attribute is parsed from the HTML. Let’s say you want to store the color in an attribute called `data-color`, here’s how you would do that:
+
+```js
+const CustomParagraph = Paragraph.extend({
+  addAttributes() {
+    return {
+      color: {
+        default: null,
+        // Customize the HTML parsing (for example, to load the initial content)
+        parseHTML: element => {
+          return {
+            color: element.getAttribute('data-color'),
+          }
+        },
+        // … and customize the HTML rendering.
+        renderHTML: attributes => {
+          return {
+            'data-color': attributes.color,
+            style: `color: ${attributes.color}`,
+          }
+        },
+      },
+    }
+  },
+})
+
+// Result:
+// <p data-color="pink" style="color: pink">Example Text</p>
+```
+
+You can disable the rendering of attributes, if you pass `rendered: false`.
+
+#### Extend existing attributes
+If you want to add an attribute to an extension and keep existing attributes, you can access them through `this.parent()`. In some cases, it is undefined, so make sure to check for that case, or use optional chaining `this.parent?.()`
+
+```js
+const CustomTableCell = TableCell.extend({
+  addAttributes() {
+    return {
+      ...this.parent?.(),
+      myCustomAttribute: {
+        // …
+      },
+    }
+  },
+})
+```
+
+### Global Attributes
+Attributes can be applied to multiple extensions at once. That’s useful for text alignment, line height, color, font family, and other styling related attributes.
+
+Take a closer look at [the full source code](https://github.com/ueberdosis/tiptap/tree/main/packages/extension-text-align) of the [`TextAlign`](/api/extensions/text-align) extension to see a more complex example. But here is how it works in a nutshell:
+
+```js
+import { Extension } from '@tiptap/core'
+
+const TextAlign = Extension.create({
+  addGlobalAttributes() {
+    return [
+      {
+        // Extend the following extensions
+        types: [
+          'heading',
+          'paragraph',
+        ],
+        // … with those attributes
+        attributes: {
+          textAlign: {
+            default: 'left',
+            renderHTML: attributes => ({
+              style: `text-align: ${attributes.textAlign}`,
+            }),
+            parseHTML: element => ({
+              textAlign: element.style.textAlign || 'left',
+            }),
+          },
+        },
+      },
+    ]
+  },
+})
+```
+
+### Render HTML
+With the `renderHTML` function you can control how an extension is rendered to HTML. We pass an attributes object to it, with all local attributes, global attributes, and configured CSS classes. Here is an example from the `Bold` extension:
+
+```js
+renderHTML({ HTMLAttributes }) {
+  return ['strong', HTMLAttributes, 0]
+},
+```
+
+The first value in the array should be the name of HTML tag. If the second element is an object, it’s interpreted as a set of attributes. Any elements after that are rendered as children.
+
+The number zero (representing a hole) is used to indicate where the content should be inserted. Let’s look at the rendering of the `CodeBlock` extension with two nested tags:
+
+```js
+renderHTML({ HTMLAttributes }) {
+  return ['pre', ['code', HTMLAttributes, 0]]
+},
+```
+
+If you want to add some specific attributes there, import the `mergeAttributes` helper from `@tiptap/core`:
+
+```js
+import { mergeAttributes } from '@tiptap/core'
+
+// ...
+
+renderHTML({ HTMLAttributes }) {
+  return ['a', mergeAttributes(HTMLAttributes, { rel: this.options.rel }), 0]
+},
+```
+
+### Parse HTML
+The `parseHTML()` function tries to load the editor document from HTML. The function gets the HTML DOM element passed as a parameter, and is expected to return an object with attributes and their values. Here is a simplified example from the [`Bold`](/api/marks/bold) mark:
+
+```js
+parseHTML() {
+  return [
+    {
+      tag: 'strong',
+    },
+  ]
+},
+```
+
+This defines a rule to convert all `<strong>` tags to `Bold` marks. But you can get more advanced with this, here is the full example from the extension:
+
+```js
+parseHTML() {
+  return [
+    // <strong>
+    {
+      tag: 'strong',
+    },
+    // <b>
+    {
+      tag: 'b',
+      getAttrs: node => node.style.fontWeight !== 'normal' && null,
+    },
+    // <span style="font-weight: bold"> and <span style="font-weight: 700">
+    {
+      style: 'font-weight',
+      getAttrs: value => /^(bold(er)?|[5-9]\d{2,})$/.test(value as string) && null,
+    },
+  ]
+},
+```
+
+This looks for `<strong>` and `<b>` tags, and any HTML tag with an inline style setting the `font-weight` to bold.
+
+As you can see, you can optionally pass a `getAttrs` callback, to add more complex checks, for example for specific HTML attributes. The callback gets passed the HTML DOM node, except when checking for the `style` attribute, then it’s the value.
+
+### Commands
+```js
+import Paragraph from '@tiptap/extension-paragraph'
+
+const CustomParagraph = Paragraph.extend({
+  addCommands() {
+    return {
+      paragraph: () => ({ commands }) => {
+        return commands.toggleNode('paragraph', 'paragraph')
+      },
+    }
+  },
+})
+```
+
+:::warning Use the commands parameter inside of addCommands
+To access other commands inside `addCommands` use the `commands` parameter that’s passed to it.
+:::
+
+### Keyboard shortcuts
+Most core extensions come with sensible keyboard shortcut defaults. Depending on what you want to build, you’ll likely want to change them though. With the `addKeyboardShortcuts()` method you can overwrite the predefined shortcut map:
+
+```js
+// Change the bullet list keyboard shortcut
+import BulletList from '@tiptap/extension-bullet-list'
+
+const CustomBulletList = BulletList.extend({
+  addKeyboardShortcuts() {
+    return {
+      'Mod-l': () => this.editor.commands.toggleBulletList(),
+    }
+  },
+})
+```
+
+### Input rules
+With input rules you can define regular expressions to listen for user inputs. They are used for markdown shortcuts, or for example to convert text like `(c)` to a `©` (and many more) with the [`Typography`](/api/extensions/typography) extension. Use the `markInputRule` helper function for marks, and the `nodeInputRule` for nodes.
+
+By default text between two tildes on both sides is transformed to ~~striked text~~. If you want to think one tilde on each side is enough, you can overwrite the input rule like this:
+
+```js
+// Use the ~single tilde~ markdown shortcut
+import Strike from '@tiptap/extension-strike'
+import { markInputRule } from '@tiptap/core'
+
+// Default:
+// const inputRegex = /(?:^|\s)((?:~~)((?:[^~]+))(?:~~))$/gm
+
+// New:
+const inputRegex = /(?:^|\s)((?:~)((?:[^~]+))(?:~))$/gm
+
+const CustomStrike = Strike.extend({
+  addInputRules() {
+    return [
+      markInputRule(inputRegex, this.type),
+    ]
+  },
+})
+```
+
+### Paste rules
+Paste rules work like input rules (see above) do. But instead of listening to what the user types, they are applied to pasted content.
+
+There is one tiny difference in the regular expression. Input rules typically end with a `$` dollar sign (which means “asserts position at the end of a line”), paste rules typically look through all the content and don’t have said `$` dollar sign.
+
+Taking the example from above and applying it to the paste rule would look like the following example.
+
+```js
+// Check pasted content for the ~single tilde~ markdown syntax
+import Strike from '@tiptap/extension-strike'
+import { markPasteRule } from '@tiptap/core'
+
+// Default:
+// const pasteRegex = /(?:^|\s)((?:~~)((?:[^~]+))(?:~~))/gm
+
+// New:
+const pasteRegex = /(?:^|\s)((?:~)((?:[^~]+))(?:~))/gm
+
+const CustomStrike = Strike.extend({
+  addPasteRules() {
+    return [
+      markPasteRule(pasteRegex, this.type),
+    ]
+  },
+})
+```
+
+### Events
+You can even move your [event listeners](/api/events) to a separate extension. Here is an example with listeners for all events:
+
+```js
+import { Extension } from '@tiptap/core'
+
+const CustomExtension = Extension.create({
+  onCreate() {
+    // The editor is ready.
+  },
+  onUpdate() {
+    // The content has changed.
+  },
+  onSelection() {
+    // The selection has changed.
+  },
+  onTransaction({ transaction }) {
+    // The editor state has changed.
+  },
+  onFocus({ event }) {
+    // The editor is focused.
+  },
+  onBlur({ event }) {
+    // The editor isn’t focused anymore.
+  },
+  onDestroy() {
+    // The editor is being destroyed.
+  },
+})
+```
+
+### ProseMirror Plugins (Advanced)
+After all, tiptap is built on ProseMirror and ProseMirror has a pretty powerful plugin API, too. To access that directly, use `addProseMirrorPlugins()`.
+
+#### Existing plugins
+You can wrap existing ProseMirror plugins in tiptap extensions like shown in the example below.
+
+```js
+import { history } from 'prosemirror-history'
+
+const History = Extension.create({
+  addProseMirrorPlugins() {
+    return [
+      history(),
+      // …
+    ]
+  },
+})
+```
+
+#### Access the ProseMirror API
+To hook into events, for example a click, double click or when content is pasted, you can pass event handlers as `editorProps` to the [editor](/api/editor). Or you can add them to a tiptap extension like shown in the below example.
+
+```js
+import { Extension } from '@tiptap/core'
+import { Plugin, PluginKey } from 'prosemirror-state'
+
+export const EventHandler = Extension.create({
+  name: 'eventHandler',
+
+  addProseMirrorPlugins() {
+    return [
+      new Plugin({
+        key: new PluginKey('eventHandler'),
+        props: {
+          handleClick(view, pos, event) { /* … */ },
+          handleDoubleClick(view, pos, event) { /* … */ },
+          handlePaste(view, event, slice) { /* … */ },
+          // … and many, many more.
+          // Here is the full list: https://prosemirror.net/docs/ref/#view.EditorProps
+        },
+      }),
+    ]
+  },
+})
+```
+
+### Node views (Advanced)
+For advanced use cases, where you need to execute JavaScript inside your nodes, for example to render a sophisticated link preview, you need to learn about node views.
+
+They are really powerful, but also complex. In a nutshell, you need to return a parent DOM element, and a DOM element where the content should be rendered in. Look at the following, simplified example:
+
+```js
+import Link from '@tiptap/extension-link'
+
+const CustomLink = Link.extend({
+  addNodeView() {
+    return () => {
+      const container = document.createElement('div')
+
+      container.addEventListener('click', event => {
+        alert('clicked on the container')
+      })
+
+      const content = document.createElement('div')
+      container.append(content)
+
+      return {
+        dom: container,
+        contentDOM: content,
+      }
+    }
+  },
+})

-## Introduction
-One of the strength of tiptap is it’s extendability. You don’t depend on the provided extensions, it’s intended to extend the editor to your liking. With custom extensions you can add new content types and new functionalities, on top of what already exists or from scratch.
-
-## Customize existing extensions
-Let’s say you want to change the keyboard shortcuts for the bullet list. You should start by looking at [the source code of the `BulletList` extension](https://github.com/ueberdosis/tiptap/blob/main/packages/extension-bullet-list/src/bullet-list.ts) and find the part you would like to change. In that case, the keyboard shortcut, and just that.
-
-Every extension has an `extend()` method, which takes an object with everything you want to change or add to it. For the bespoken example, your code could like that:
-
-```js
-// 1. Import the extension
-import BulletList from '@tiptap/extension-bullet-list'
-
-// 2. Overwrite the keyboard shortcuts
-const CustomBulletList = BulletList.extend({
-  addKeyboardShortcuts() {
-    return {
-      'Mod-l': () => this.editor.commands.toggleBulletList(),
-    }
-  },
-})
-
-// 3. Add the custom extension to your editor
-new Editor({
-  extensions: [
-    CustomBulletList(),
-    // …
-  ],
-})
-```
-
-The same applies to every aspect of an existing extension, except to the name. Let’s look at all the things that you can change through the extend method. We focus on one aspect in every example, but you can combine all those examples and change multiple aspects in one `extend()` call too.
-
-### Name
-The extension name is used in a whole lot of places and changing it isn’t too easy. If you want to change the name of an existing extension, we would recommended to copy the whole extension and change the name in all occurrences.
-
-The extension name is also part of the JSON. If you [store your content as JSON](/guide/output#option-1-json), you need to change the name there too.
-
-### Priority
-The priority defines the order in which extensions are registered. The default priority is `100`, that’s what most extension have. Extensions with a higher priority will be loaded earlier.
-
-```js
-import Link from '@tiptap/extension-link'
-
-const CustomLink = Link.extend({
-  priority: 1000,
-})
-```
-
-The order in which extensions are loaded influences two things:
-
-1. #### Plugin order
-   Plugins of extensions with a higher priority will run first.
-
-2. #### Schema order
-   The [`Link`](/api/marks/link) mark for example has a higher priority, which means it’ll be rendered as `<a href="…"><strong>Example</strong></a>` instead of `<strong><a href="…">Example</></strong>`.
-
-### Settings
-All settings can be configured through the extension anyway, but if you want to change the default settings, for example to provide a library on top of tiptap for other developers, you can do it like that:
-
-```js
-import Heading from '@tiptap/extension-heading'
-
-const CustomHeading = Heading.extend({
-  defaultOptions: {
-    ...Heading.options,
-    levels: [1, 2, 3],
-  },
-})
-```
-
-### Schema
-tiptap works with a strict schema, which configures how the content can be structured, nested, how it behaves and many more things. You [can change all aspects of the schema](/api/schema) for existing extensions. Let’s walk through a few common use cases.
-
-The default `Blockquote` extension can wrap other nodes, like headings. If you want to allow nothing but paragraphs in your blockquotes, this is how you could achieve it:
-
-```js
-// Blockquotes must only include paragraphs
-import Blockquote from '@tiptap/extension-blockquote'
-
-const CustomBlockquote = Blockquote.extend({
-  content: 'paragraph*',
-})
-```
-
-The schema even allows to make your nodes draggable, that’s what the `draggable` option is for, which defaults to `false`.
-
-```js
-// Draggable paragraphs
-import Paragraph from '@tiptap/extension-paragraph'
-
-const CustomParagraph = Paragraph.extend({
-  draggable: true,
-})
-```
-
-That’s just two tiny examples, but [the underlying ProseMirror schema](https://prosemirror.net/docs/ref/#model.SchemaSpec) is really powerful. You should definitely read the documentation to understand all the nifty details.
-
-### Attributes
-You can use attributes to store additional information in the content. Let’s say you want to extend the default paragraph extension to enable paragraphs to have different colors:
-
-```js
-const CustomParagraph = Paragraph.extend({
-  addAttributes() {
-    // Return an object with attribute configuration
-    return {
-      color: {
-        default: 'pink',
-      },
-    },
-  },
-})
-
-// Result:
-// <p color="pink">Example Text</p>
-```
-
-That’s already enough to tell tiptap about the new attribute, and set `'pink'` as the default value. All attributes will be rendered as a HTML attribute by default, and parsed as attributes from the content.
-
-Let’s stick with the color example and assume you’ll want to add an inline style to actually color the text. With the `renderHTML` function you can return HTML attributes which will be rendered in the output.
-
-This examples adds a style HTML attribute based on the value of color:
-
-```js
-const CustomParagraph = Paragraph.extend({
-  addAttributes() {
-    return {
-      color: {
-        default: null,
-        // Take the attribute values
-        renderHTML: attributes => {
-          // … and return an object with HTML attributes.
-          return {
-            style: `color: ${attributes.color}`,
-          }
-        },
-      },
-    }
-  },
-})
-
-// Result:
-// <p style="color: pink">Example Text</p>
-```
-
-You can also control how the attribute is parsed from the HTML. Let’s say you want to store the color in an attribute called `data-color`, here’s how you would do that:
-
-```js
-const CustomParagraph = Paragraph.extend({
-  addAttributes() {
-    return {
-      color: {
-        default: null,
-        // Customize the HTML parsing (for example, to load the initial content)
-        parseHTML: element => {
-          return {
-            color: element.getAttribute('data-color'),
-          }
-        },
-        // … and customize the HTML rendering.
-        renderHTML: attributes => {
-          return {
-            'data-color': attributes.color,
-            style: `color: ${attributes.color}`,
-          }
-        },
-      },
-    }
-  },
-})
-
-// Result:
-// <p data-color="pink" style="color: pink">Example Text</p>
-```
-
-You can disable the rendering of attributes, if you pass `rendered: false`.
-
-#### Extend existing attributes
-If you want to add an attribute to an extension and keep existing attributes, you can access them through `this.parent()`. In some cases, it is undefined, so make sure to check for that case, or use optional chaining `this.parent?.()`
-
-```js
-const CustomTableCell = TableCell.extend({
-  addAttributes() {
-    return {
-      ...this.parent?.(),
-      myCustomAttribute: {
-        // …
-      },
-    }
-  },
-})
-```
-
-### Global Attributes
-Attributes can be applied to multiple extensions at once. That’s useful for text alignment, line height, color, font family, and other styling related attributes.
-
-Take a closer look at [the full source code](https://github.com/ueberdosis/tiptap/tree/main/packages/extension-text-align) of the [`TextAlign`](/api/extensions/text-align) extension to see a more complex example. But here is how it works in a nutshell:
-
-```js
-import { Extension } from '@tiptap/core'
-
-const TextAlign = Extension.create({
-  addGlobalAttributes() {
-    return [
-      {
-        // Extend the following extensions
-        types: [
-          'heading',
-          'paragraph',
-        ],
-        // … with those attributes
-        attributes: {
-          textAlign: {
-            default: 'left',
-            renderHTML: attributes => ({
-              style: `text-align: ${attributes.textAlign}`,
-            }),
-            parseHTML: element => ({
-              textAlign: element.style.textAlign || 'left',
-            }),
-          },
-        },
-      },
-    ]
-  },
-})
-```
-
-### Render HTML
-With the `renderHTML` function you can control how an extension is rendered to HTML. We pass an attributes object to it, with all local attributes, global attributes, and configured CSS classes. Here is an example from the `Bold` extension:
-
-```js
-renderHTML({ HTMLAttributes }) {
-  return ['strong', HTMLAttributes, 0]
-},
-```
-
-The first value in the array should be the name of HTML tag. If the second element is an object, it’s interpreted as a set of attributes. Any elements after that are rendered as children.
-
-The number zero (representing a hole) is used to indicate where the content should be inserted. Let’s look at the rendering of the `CodeBlock` extension with two nested tags:
-
-```js
-renderHTML({ HTMLAttributes }) {
-  return ['pre', ['code', HTMLAttributes, 0]]
-},
-```
-
-If you want to add some specific attributes there, import the `mergeAttributes` helper from `@tiptap/core`:
-
-```js
-import { mergeAttributes } from '@tiptap/core'
-
-// ...
-
-renderHTML({ HTMLAttributes }) {
-  return ['a', mergeAttributes(HTMLAttributes, { rel: this.options.rel }), 0]
-},
-```
-
-### Parse HTML
-The `parseHTML()` function tries to load the editor document from HTML. The function gets the HTML DOM element passed as a parameter, and is expected to return an object with attributes and their values. Here is a simplified example from the [`Bold`](/api/marks/bold) mark:
-
-```js
-parseHTML() {
-  return [
-    {
-      tag: 'strong',
-    },
-  ]
-},
-```
-
-This defines a rule to convert all `<strong>` tags to `Bold` marks. But you can get more advanced with this, here is the full example from the extension:
-
-```js
-parseHTML() {
-  return [
-    // <strong>
-    {
-      tag: 'strong',
-    },
-    // <b>
-    {
-      tag: 'b',
-      getAttrs: node => node.style.fontWeight !== 'normal' && null,
-    },
-    // <span style="font-weight: bold"> and <span style="font-weight: 700">
-    {
-      style: 'font-weight',
-      getAttrs: value => /^(bold(er)?|[5-9]\d{2,})$/.test(value as string) && null,
-    },
-  ]
-},
-```
-
-This looks for `<strong>` and `<b>` tags, and any HTML tag with an inline style setting the `font-weight` to bold.
-
-As you can see, you can optionally pass a `getAttrs` callback, to add more complex checks, for example for specific HTML attributes. The callback gets passed the HTML DOM node, except when checking for the `style` attribute, then it’s the value.
-
-### Commands
-```js
-import Paragraph from '@tiptap/extension-paragraph'
-
-const CustomParagraph = Paragraph.extend({
-  addCommands() {
-    return {
-      paragraph: () => ({ commands }) => {
-        return commands.toggleNode('paragraph', 'paragraph')
-      },
-    }
-  },
-})
-```
-
-:::warning Use the commands parameter inside of addCommands
-All commands are also available through ~~this.editor.commands~~, but inside of `addCommands` you must use the `commands` parameter that’s passed to it.
-:::
-
-### Keyboard shortcuts
-Most core extensions come with sensible keyboard shortcut defaults. Depending on what you want to build, you’ll likely want to change them though. With the `addKeyboardShortcuts()` method you can overwrite the predefined shortcut map:
-
-```js
-// Change the bullet list keyboard shortcut
-import BulletList from '@tiptap/extension-bullet-list'
-
-const CustomBulletList = BulletList.extend({
-  addKeyboardShortcuts() {
-    return {
-      'Mod-l': () => this.editor.commands.toggleBulletList(),
-    }
-  },
-})
-```
-
-### Input rules
-With input rules you can define regular expressions to listen for user inputs. They are used for markdown shortcuts, or for example to convert text like `(c)` to a `©` (and many more) with the [`Typography`](/api/extensions/typography) extension. Use the `markInputRule` helper function for marks, and the `nodeInputRule` for nodes.
-
-By default text between two tildes on both sides is transformed to ~~striked text~~. If you want to think one tilde on each side is enough, you can overwrite the input rule like this:
-
-```js
-// Use the ~single tilde~ markdown shortcut
-import Strike from '@tiptap/extension-strike'
-import { markInputRule } from '@tiptap/core'
-
-// Default:
-// const inputRegex = /(?:^|\s)((?:~~)((?:[^~]+))(?:~~))$/gm
-
-// New:
-const inputRegex = /(?:^|\s)((?:~)((?:[^~]+))(?:~))$/gm
-
-const CustomStrike = Strike.extend({
-  addInputRules() {
-    return [
-      markInputRule(inputRegex, this.type),
-    ]
-  },
-})
-```
-
-### Paste rules
-Paste rules work like input rules (see above) do. But instead of listening to what the user types, they are applied to pasted content.
-
-There is one tiny difference in the regular expression. Input rules typically end with a `$` dollar sign (which means “asserts position at the end of a line”), paste rules typically look through all the content and don’t have said `$` dollar sign.
-
-Taking the example from above and applying it to the paste rule would look like the following example.
-
-```js
-// Check pasted content for the ~single tilde~ markdown syntax
-import Strike from '@tiptap/extension-strike'
-import { markPasteRule } from '@tiptap/core'
-
-// Default:
-// const pasteRegex = /(?:^|\s)((?:~~)((?:[^~]+))(?:~~))/gm
-
-// New:
-const pasteRegex = /(?:^|\s)((?:~)((?:[^~]+))(?:~))/gm
-
-const CustomStrike = Strike.extend({
-  addPasteRules() {
-    return [
-      markPasteRule(pasteRegex, this.type),
-    ]
-  },
-})
-```
-
-### Events
-You can even move your [event listeners](/api/events) to a separate extension. Here is an example with listeners for all events:
-
-```js
-import { Extension } from '@tiptap/core'
-
-const CustomExtension = Extension.create({
-  onCreate() {
-    // The editor is ready.
-  },
-  onUpdate() {
-    // The content has changed.
-  },
-  onSelection() {
-    // The selection has changed.
-  },
-  onTransaction({ transaction }) {
-    // The editor state has changed.
-  },
-  onFocus({ event }) {
-    // The editor is focused.
-  },
-  onBlur({ event }) {
-    // The editor isn’t focused anymore.
-  },
-  onDestroy() {
-    // The editor is being destroyed.
-  },
-})
-```
-
-### ProseMirror Plugins (Advanced)
-After all, tiptap is built on ProseMirror and ProseMirror has a pretty powerful plugin API, too. To access that directly, use `addProseMirrorPlugins()`.
-
-#### Existing plugins
-You can wrap existing ProseMirror plugins in tiptap extensions like shown in the example below.
-
-```js
-import { history } from 'prosemirror-history'
-
-const History = Extension.create({
-  addProseMirrorPlugins() {
-    return [
-      history(),
-      // …
-    ]
-  },
-})
-```
-
-#### Access the ProseMirror API
-To hook into events, for example a click, double click or when content is pasted, you can pass event handlers as `editorProps` to the [editor](/api/editor). Or you can add them to a tiptap extension like shown in the below example.
-
-```js
-import { Extension } from '@tiptap/core'
-import { Plugin, PluginKey } from 'prosemirror-state'
-
-export const EventHandler = Extension.create({
-  name: 'eventHandler',
-
-  addProseMirrorPlugins() {
-    return [
-      new Plugin({
-        key: new PluginKey('eventHandler'),
-        props: {
-          handleClick(view, pos, event) { /* … */ },
-          handleDoubleClick(view, pos, event) { /* … */ },
-          handlePaste(view, event, slice) { /* … */ },
-          // … and many, many more.
-          // Here is the full list: https://prosemirror.net/docs/ref/#view.EditorProps
-        },
-      }),
-    ]
-  },
-})
-```
-
-### Node views (Advanced)
-For advanced use cases, where you need to execute JavaScript inside your nodes, for example to render a sophisticated link preview, you need to learn about node views.
-
-They are really powerful, but also complex. In a nutshell, you need to return a parent DOM element, and a DOM element where the content should be rendered in. Look at the following, simplified example:
-
-```js
-import Link from '@tiptap/extension-link'
-
-const CustomLink = Link.extend({
-  addNodeView() {
-    return () => {
-      const container = document.createElement('div')
-
-      container.addEventListener('click', event => {
-        alert('clicked on the container')
-      })
-
-      const content = document.createElement('div')
-      container.append(content)
-
-      return {
-        dom: container,
-        contentDOM: content,
-      }
-    }
-  },
-})
-```
-
