A markdown-it renderer plugin by using Incremental DOM.
Let's see key features: https://yhatt.github.io/markdown-it-incremental-dom/ or docs.md
Requirement
- markdown-it >= 4.0.0 (Recommend latest version >= 8.4.0, that this plugin use it)
- Incremental DOM >= 0.5.x
Examples
Node
import * as IncrementalDOM from 'incremental-dom'
import MarkdownIt from 'markdown-it'
import MarkdownItIncrementalDOM from 'markdown-it-incremental-dom'
const md = new MarkdownIt().use(MarkdownItIncrementalDOM, IncrementalDOM)
IncrementalDOM.patch(
document.getElementById('target'),
md.renderToIncrementalDOM('# Hello, Incremental DOM!')
)
Browser
Define as window.markdownitIncrementalDOM
.

IncrementalDOM.patch(
document.getElementById('target'),
md.renderToIncrementalDOM('# Hello, Incremental DOM!')
)
</script>
</body>
</html>
CDN
You can use the recent version through CDN provides by jsDelivr.
<script src="https://cdn.jsdelivr.net/npm/markdown-it-incremental-dom@2/dist/markdown-it-incremental-dom.min.js"></script>
Installation
We recommend using yarn to install.
$ yarn add incremental-dom markdown-it
$ yarn add markdown-it-incremental-dom
If you wanna use npm, try this:
$ npm install incremental-dom markdown-it --save
$ npm install markdown-it-incremental-dom --save
Usage
When injecting this plugin by .use()
, you should pass Incremental DOM class as second argument. (window.IncrementalDOM
by default)
import * as IncrementalDOM from 'incremental-dom'
import MarkdownIt from 'markdown-it'
import MarkdownItIncrementalDOM from 'markdown-it-incremental-dom'
const md = new MarkdownIt().use(MarkdownItIncrementalDOM, IncrementalDOM)
If it is succeed, 2 new rendering methods would be injected to instance.
TIPS: This plugin keeps default rendering methods
render()
andrenderInline()
.
Option
You can pass option object as third argument. See below:
new MarkdownIt().use(MarkdownItIncrementalDOM, IncrementalDOM, {
incrementalizeDefaultRules: false,
})
incrementalizeDefaultRules
: For better performance, this plugin would override a few default renderer rules only when you calls injected methods. If the other plugins that override default rules have occurred any problem, You can disable overriding by settingfalse
. (true
by default)
Rendering methods
MarkdownIt.renderToIncrementalDOM(src[, env])
=> Function
Similar to MarkdownIt.render(src[, env])
but it returns a function for Incremental DOM. It means doesn't render Markdown immediately.
You must render to DOM by using IncrementalDOM.patch(node, description)
. Please pass the returned function to the description argument. For example:
const node = document.getElementById('#target')
const func = md.renderToIncrementalDOM('# Hello, Incremental DOM!')
// It would render "<h1>Hello, Incremental DOM!</h1>" to <div id="target">
IncrementalDOM.patch(node, func)
MarkdownIt.renderInlineToIncrementalDOM(src[, env])
=> Function
Similar to MarkdownIt.renderToIncrementalDOM
but it wraps MarkdownIt.renderInline(src[, env])
.
Renderer property
get MarkdownIt.IncrementalDOMRenderer
=> Renderer
Returns Renderer
instance that includes Incremental DOM support.
It will inject Incremental DOM features into the current state of MarkdownIt.renderer
at getting this property.
NOTE: This property is provided for the expert. Normally you should use
renderToIncrementalDOM()
.But it might be useful if you have to parse Markdown and operate tokens manually.
const md = new MarkdownIt() const tokens = md.parse('# Hello') // ...You can operate tokens here... const patch = md.IncrementalDOMRenderer.render(tokens, md.options) IncrementalDOM.patch(document.body, patch)
