Marksy
A markdown to custom components library. Supports any virtual DOM library.
Installation
npm install marksy
Usage
import React, {createElement} from 'React';
import marksy from 'marksy'
// const marksy = require('marksy').marksy
const compile = marksy({
// Pass in whatever creates elements for your
// virtual DOM library. h('h1', {})
createElement,
// You can override the default elements with
// custom VDOM trees
elements: {
h1 ({id, children}) {
return <h1 className="my-custom-class">{children}</h1>
},
h2 ({id, children}) {},
h3 ({id, children}) {},
h4 ({id, children}) {},
blockquote ({children}) {},
hr () {},
ol ({children}) {},
ul ({children}) {},
p ({children}) {},
table ({children}) {},
thead ({children}) {},
tbody ({children}) {},
tr ({children}) {},
th ({children}) {},
td ({children}) {},
a ({href, title, target, children}) {},
strong ({children}) {},
em ({children}) {},
br () {},
del ({children}) {},
img ({src, alt}) {},
code ({language, code}) {},
codespan ({children}) {},
},
});
const compiled = compile('# hello', {
// Options passed to "marked" (https://www.npmjs.com/package/marked)
});
compiled.tree // The React tree of components
compiled.toc // The table of contents, based on usage of headers
Components
You can also add your own custom components:
This will be converted to the component above. You can pass in any kind of props, as if it was normal code. If you are not familiar with h
, this is a convention for creating elements and components in virtual dom implementations.
Jsx
You can take one step further and create components wherever you want in the markdown, using jsx. You will have to import marksy/jsx
. This build of marksy includes babel transpiler which will convert any HTML to elements and allow for custom components. Note that this will increase your bundle size sagnificantly:
Context
You might need to pass in general information to your custom elements and components. You can pass in a context to do so:
import React, {createElement} from 'react'
import marksy from 'marksy/jsx'
const compile = marksy({
createElement,
elements: {
h1(props) {
return <h1>{props.context.foo}</h1>
}
},
components: {
MyCustomComponent (props) {
return <h1>{props.context.foo}</h1>
}
}
})
compile('<MyCustomComponent />', null, {
foo: 'bar'
})
Code highlighting
To enable code highlighting you just need to add a method that does the transformation. Here is an example with Highlight.js, but you could also use Prism. Both of them support server side rendering. For example:
import {createElement} from 'react'
import 'highlight.js/styles/github.css';
import hljs from 'highlight.js/lib/highlight';
import hljsJavascript from 'highlight.js/lib/languages/javascript';
import marksy from 'marksy/jsx'
hljs.registerLanguage('javascript', hljsJavascript);
const compile = marksy({
createElement,
highlight(language, code) {
return hljs.highlight(language, code).value
}
})
The elements returned is:
<pre>
<code class="language-js">
...code...
</code>
</pre>
Meaning that the code
element is added a classname based on the language.
