## Why I built tiptap
|
|
I was looking for a text editor for [Vue.js](https://github.com/vuejs/vue) and found some solutions that didn't really satisfy me. The editor should be easy to extend and not based on old dependencies such as jQuery. For React there is already a great editor called [Slate.js](https://github.com/ianstormtaylor/slate), which impresses with its modularity. I came across [Prosemirror](https://github.com/prosemirror) and decided to build on it. Prosemirror is a toolkit for building rich-text editors that are already in use at many well-known companies such as *Atlassian* or *New York Times*.
|
|
|
|
### What means `renderless`?
|
|
|
|
With renderless components you'll have (almost) full control over markup and styling. I don't want to tell you what a menu should look like or where it should be rendered in the DOM. That's all up to you. There is also a [good article](https://adamwathan.me/renderless-components-in-vuejs/) about renderless components by Adam Wathan.
|
|
|
|
### How is the data stored under the hood?
|
|
|
|
You can save your data as a raw `HTML` string or can get a `JSON`-serializable representation of your document. And of course, you can pass these two types back to the editor.
|
|
|
|
## Examples

## Extensions
|
|
|
|
By default, the editor will only support paragraphs. Other nodes and marks are available as **extensions**. There is a package called `tiptap-extensions` with the most basic nodes, marks, and plugins.
|
|
|
|
### Available Extensions

|
<div>
|
|
<editor-menu-bar :editor="editor">
|
|

|
|
<button :class="{ 'is-active': isActive.bold() }" @click="commands.bold">
|
|
Bold
|
|
</button>
|
|
</div>

|
|
},
|
|
data() {
|
|
return {
|
|
editor: new Editor({
|
|
extensions: [
|
|
new Blockquote(),
|
|
new CodeBlock(),
|
|
new HardBreak(),
|
|
new Heading({ levels: [1, 2, 3] }),

|
|
`,
|
|
}),
|
|
}
|
|
},
|
|
beforeDestroy() {
|
|
this.editor.destroy()
|
|
},
|
|
}
|
|
</script>
|
|
```
|
|
|
|
### Create Custom Extensions
|
|
|
|
The most powerful feature of tiptap is that you can create your own extensions. There are 3 types of extensions.
|
|
|
|
| **Type** | **Description** |
|
|
| --- | --- |
|
|
| `Extension` | The most basic type. It's useful to register some [Prosemirror plugins](https://prosemirror.net/docs/guide/) or some input rules. |
|
|
| `Node` | Add a custom node. Nodes are block elements like a headline or a paragraph. |
|
|
| `Mark` | Add a custom mark. Marks are used to add extra styling or other information to inline content like a strong tag or links. |
|
|
|
|
### Extension Class
|
|
|
|
| **Method** | **Type** | **Default** | **Description** |
|
|
| --- | :---: | :---: | --- |
|
|
| `get name()` | `String` | `null` | Define a name for your extension. |
|
|
| `get defaultOptions()` | `Object` | `{}` | Define some default options. The options are available as `this.$options`. |
|
|
| `get plugins()` | `Array` | `[]` | Define a list of [Prosemirror plugins](https://prosemirror.net/docs/guide/). |
|
|
| `keys({ schema })` | `Object` | `null` | Define some keybindings. |
|
|
| `commands({ schema, attrs })` | `Object` | `null` | Define a command. |
|
|
| `inputRules({ schema })` | `Array` | `[]` | Define a list of input rules. |
|
|
| `pasteRules({ schema })` | `Array` | `[]` | Define a list of paste rules. |
|
|
|
|
### Node|Mark Class
|
|
|
|
| **Method** | **Type** | **Default** | **Description** |
|
|
| --- | :---: | :---: | --- |
|
|
| `get name()` | `String` | `null` | Define a name for your node or mark. |
|
|
| `get defaultOptions()` | `Object` | `{}` | Define some default options. The options are available as `this.$options`. |
|
|
| `get schema()` | `Object` | `null` | Define a [schema](https://prosemirror.net/docs/guide/#schema). |
|
|
| `get view()` | `Object` | `null` | Define a node view as a vue component. |
|
|
| `keys({ type, schema })` | `Object` | `null` | Define some keybindings. |
|
|
| `commands({ type, schema, attrs })` | `Object` | `null` | Define a command. For example this is used for menus to convert to this node or mark. |
|
|
| `inputRules({ type, schema })` | `Array` | `[]` | Define a list of input rules. |
|
|
| `pasteRules({ type, schema })` | `Array` | `[]` | Define a list of paste rules. |
|
|
| `get plugins()` | `Array` | `[]` | Define a list of [Prosemirror plugins](https://prosemirror.net/docs/guide/). |
|
|
|
|
### Create a Node
|
|
|
|
Let's take a look at a real example. This is basically how the default `blockquote` node from [`tiptap-extensions`](https://www.npmjs.com/package/tiptap-extensions) looks like.
|
|
|
|
```js
|
|
import { Node } from 'tiptap'
|
|
import { wrappingInputRule, setBlockType, toggleWrap } from 'tiptap-commands'
|
|
|
|
export default class BlockquoteNode extends Node {
|
|
|
|
// choose a unique name
|
|
get name() {
|
|
return 'blockquote'
|
|
}
|
|
|
|
// the prosemirror schema object
|
|
// take a look at https://prosemirror.net/docs/guide/#schema for a detailed explanation
|
|
get schema() {
|
|
return {
|
|
content: 'block+',
|
|
group: 'block',
|
|
defining: true,
|
|
draggable: false,
|
|
// define how the editor will detect your node from pasted HTML
|
|
// every blockquote tag will be converted to this blockquote node
|
|
parseDOM: [
|
|
{ tag: 'blockquote' },
|
|
],
|
|
// this is how this node will be rendered
|
|
// in this case a blockquote tag with a class called `awesome-blockquote` will be rendered
|
|
// the '0' stands for its text content inside
|
|
toDOM: () => ['blockquote', { class: 'awesome-blockquote' }, 0],
|
|
}
|
|
}
|
|
|
|
// this command will be called from menus to add a blockquote
|
|
// `type` is the prosemirror schema object for this blockquote
|
|
// `schema` is a collection of all registered nodes and marks
|
|
commands({ type, schema }) {
|
|
return () => toggleWrap(type)
|
|
}
|
|
|
|
// here you can register some shortcuts
|
|
// in this case you can create a blockquote with `ctrl` + `>`
|
|
keys({ type }) {
|
|
return {
|
|
'Ctrl->': toggleWrap(type),
|
|
}
|
|
}
|
|
|
|
// a blockquote will be created when you are on a new line and type `>` followed by a space
|
|
inputRules({ type }) {
|
|
return [
|
|
wrappingInputRule(/^\s*>\s$/, type),
|
|
]
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
### Create a Node as a Vue Component
|
|
|
|
The real power of the nodes comes in combination with Vue components. Let us build an iframe node, where you can change its URL (this can also be found in our [examples](https://github.com/heyscrumpy/tiptap/tree/master/examples/Components/Routes/Embeds)).
|
|
|
|
```js
|
|
import { Node } from 'tiptap'
|
|
|
|
export default class IframeNode extends Node {
|
|
|
|
get name() {
|
|
return 'iframe'
|
|
}
|
|
|
|
get schema() {
|
|
return {
|
|
// here you have to specify all values that can be stored in this node
|
|
attrs: {
|
|
src: {
|
|
default: null,
|
|
},
|
|
},
|
|
group: 'block',
|
|
selectable: false,
|
|
// parseDOM and toDOM is still required to make copy and paste work
|
|
parseDOM: [{
|
|
tag: 'iframe',
|
|
getAttrs: dom => ({
|
|
src: dom.getAttribute('src'),
|
|
}),
|
|
}],
|
|
toDOM: node => ['iframe', {
|
|
src: node.attrs.src,
|
|
frameborder: 0,
|
|
allowfullscreen: 'true',
|
|
}],
|
|
}
|
|
}
|
|
|
|
// return a vue component
|
|
// this can be an object or an imported component
|
|
get view() {
|
|
return {
|
|
// there are some props available
|
|
// `node` is a Prosemirror Node Object
|
|
// `updateAttrs` is a function to update attributes defined in `schema`
|
|
// `editable` is the global editor prop whether the content can be edited
|
|
props: ['node', 'updateAttrs', 'editable'],
|
|
computed: {
|
|
src: {
|
|
get() {
|
|
return this.node.attrs.src
|
|
},
|
|
set(src) {
|
|
// we cannot update `src` itself because `this.node.attrs` is immutable
|
|
this.updateAttrs({
|
|
src,
|
|
})
|
|
},
|
|
},
|
|
},
|
|
template: `
|
|
<div class="iframe">
|
|
<iframe class="iframe__embed" :src="src"></iframe>
|
|
<input class="iframe__input" type="text" v-model="src" v-if="editable" />
|
|
</div>
|
|
`,
|
|
}
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
## Development Setup
|
|
|
|
Currently, only Yarn is supported for development because of a feature called workspaces we are using here.
|
|
|
|
``` bash
|
|
# install dependencies
|
|
yarn install
|
|
|
|
# serve examples at localhost:3000
|
|
yarn start
|
|
|
|
# build dist files for packages
|
|
yarn build:packages
|
|
|
|
# build dist files for examples
|
|
yarn build:examples
|
|
```
