|
||
**[mdast][]** utility to parse markdown.
|
||
|
||
## When to use this
|
||
|
||
Use this if you want to use **[micromark][]** but need an AST.
|
||
Use **[remark][]** instead, which includes both to provide a nice interface and
|
||
hundreds of plugins.
|
||
|
||
## Install
|
||
|
||
This package is [ESM only](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c):
|
||
Node 12+ is needed to use it and it must be `import`ed instead of `require`d.
|
||
|
||
[npm][]:
|
||
|
||
```sh
|
||
npm install mdast-util-from-markdown
|
||
```
|
||
|
||
## Use
|
||
|
||
Say we have the following markdown file, `example.md`:
|
||
|
||
```markdown
|
||
## Hello, *World*!
|
||
```
|
||
|
||
And our script, `example.js`, looks as follows:
|
||
|
||
```js
|
||
import fs from 'node:fs'
|
||
import {fromMarkdown} from 'mdast-util-from-markdown'
|
||
|
||
const doc = fs.readFileSync('example.md')
|
||
|
||
const tree = fromMarkdown(doc)
|
||
|
||
console.log(tree)
|
||
```
|
||
|
||
Now, running `node example` yields (positional info removed for brevity):
|
||
|
||
```js
|
||
{
|
||
type: 'root',
|
||
children: [
|
||
{
|
||
type: 'heading',
|
||
depth: 2,
|
||
children: [
|
||
{type: 'text', value: 'Hello, '},
|
||
{
|
||
type: 'emphasis',
|
||
children: [{type: 'text', value: 'World'}]
|
||
},
|
||
{type: 'text', value: '!'}
|
||
]
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
## API
|
||
|
||
This package exports the following identifier: `fromMarkdown`.
|
||
There is no default export.
|
||
|
||
The export map supports the endorsed
|
||
[`development` condition](https://nodejs.org/api/packages.html#packages_resolving_user_conditions).
|
||
Run `node --conditions development module.js` to get instrumented dev code.
|
||
Without this condition, production code is loaded.
|
||
|
||
### `fromMarkdown(doc[, encoding][, options])`
|
||
|
||
Parse markdown to a **[mdast][]** tree.
|
||
|
||
##### Parameters
|
||
|
||
###### `doc`
|
||
|
||
Value to parse (`string` or [`Buffer`][buffer]).
|
||
|
||
###### `encoding`
|
||
|
||
[Character encoding][encoding] to understand `doc` as when it’s a
|
||
[`Buffer`][buffer] (`string`, default: `'utf8'`).
|
||
|
||
###### `options.extensions`
|
||
|
||
Array of syntax extensions (`Array<MicromarkSyntaxExtension>`, default: `[]`).
|
||
Passed to [`micromark` as `extensions`][micromark-extensions].
|
||
|
||
###### `options.mdastExtensions`
|
||
|
||
Array of mdast extensions (`Array<MdastExtension>`, default: `[]`).
|
||
|
||
##### Returns
|
||
|
||
[`Root`][root].

## Security
|
||
|
||
As markdown is sometimes used for HTML, and improper use of HTML can open you up
|
||
to a [cross-site scripting (XSS)][xss] attack, use of `mdast-util-from-markdown`
|
||
can also be unsafe.
|
||
When going to HTML, use this utility in combination with
|
||
[`hast-util-sanitize`][sanitize] to make the tree safe.
