## What is this? |
|
|
|
This package is a tiny utility that gets the textual content of a node. |
|
|
|
## When should I use this? |
|
|
|
This utility is useful when you have a node, say a heading, and want to get the |
|
text inside it. |
|
|
|
This package does not serialize markdown, that’s what |
|
[`mdast-util-to-markdown`][mdast-util-to-markdown] does. |
|
|
|
Similar packages, [`hast-util-to-string`][hast-util-to-string] and |
|
[`hast-util-to-text`][hast-util-to-text], do the same but on [hast][]. |
|
|
|
## Install |
|
|
|
This package is [ESM only][esm]. |
|
In Node.js (version 14.14+ and 16.0+), install with [npm][]: |
|
|
|
```sh |
|
npm install mdast-util-to-string |
|
``` |
|
|
|
In Deno with [`esm.sh`][esmsh]: |
|
|
|
```js |
|
import {toString} from 'https://esm.sh/mdast-util-to-string@3' |
|
``` |
|
|
|
In browsers with [`esm.sh`][esmsh]: |
|
|
|
```html |
|
<script type="module"> |
|
import {toString} from 'https://esm.sh/mdast-util-to-string@3?bundle' |
|
</script> |
|
``` |
|
|
|
## Use |
|
|
|
```js |
|
import {unified} from 'unified' |
|
import {fromMarkdown} from 'mdast-util-from-markdown' |
|
import {toString} from 'mdast-util-to-string' |
|
|
|
const tree = fromMarkdown('Some _emphasis_, **importance**, and `code`.') |
|
|
|
console.log(toString(tree)) // => 'Some emphasis, importance, and code.' |
|
``` |
|
|
|
## API |
|
|
|
This package exports the identifier [`toString`][api-tostring]. |
|
There is no default export. |
|
|
|
### `toString(value[, options])` |
|
|
|
Get the text content of a node or list of nodes. |
|
|
|
Prefers the node’s plain-text fields, otherwise serializes its children, |
|
and if the given value is an array, serialize the nodes in it. |
|
|
|
###### Parameters |
|
|
|
* `value` (`unknown`) |
|
— thing to serialize, typically [`Node`][node] |
|
* `options` ([`Options`][api-options], optional) |
|
— configuration |
|
|
|
###### Returns |
|
|
|
Serialized `value` (`string`). |
|
|
|
### `Options` |
|
|
|
Configuration (TypeScript type). |
|
|
|
###### Fields |
|
|
|
* `includeImageAlt` (`boolean`, default: `true`) |
|
— whether to use `alt` for `image`s |
|
* `includeHtml` (`boolean`, default: `true`) |
|
— whether to use `value` of HTML |
|
|
|
## Types |
|
|
|
This package is fully typed with [TypeScript][]. |
|
It exports the additional type [`Options`][api-options]. |
|
|
|
## Compatibility |
|
|
|
Projects maintained by the unified collective are compatible with all maintained |
|
versions of Node.js. |
|
As of now, that is Node.js 14.14+ and 16.0+. |
|
Our projects sometimes work with older versions, but this is not guaranteed. |
|
|
|
## Security |
|
|
|
Use of `mdast-util-to-string` does not involve **[hast][]**, user content, or |
|
change the tree, so there are no openings for [cross-site scripting (XSS)][xss] |
|
attacks. |
