## What is this?
This package is a [unified][] ([remark][]) plugin to turn soft line endings
(enters) into hard breaks (`<br>`s)
## When should I use this?
This plugin is useful if you want to display user content closer to how it was
authored, because when a user includes a line ending, itll show as such.
GitHub does this in a few places (comments, issues, PRs, and releases), but its
not semantic according to HTML and not compliant to markdown.
Markdown already has two ways to include hard breaks, namely trailing spaces and
escapes (note that `␠` represents a normal space):
```markdown
lorem␠␠
ipsum
lorem\
ipsum
```
Both will turn into `<br>`s.
If you control who authors content or can document how markdown works, its
recommended to use escapes instead.
## Install
This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:
```sh
npm install remark-breaks
```
In Deno with [`esm.sh`][esmsh]:
```js
import remarkBreaks from 'https://esm.sh/remark-breaks@4'
```
In browsers with [`esm.sh`][esmsh]:
```html
<script type="module">
import remarkBreaks from 'https://esm.sh/remark-breaks@4?bundle'
</script>
```
## Use
Say we have the following file `example.md` (note: there are no spaces after
`a`):
```markdown
Mars is
the fourth planet
```
…and a module `example.js`:
```js
import rehypeStringify from 'rehype-stringify'
import remarkBreaks from 'remark-breaks'
import remarkParse from 'remark-parse'
import remarkRehype from 'remark-rehype'
import {read} from 'to-vfile'
import {unified} from 'unified'
const file = await unified()
.use(remarkParse)
.use(remarkBreaks)
.use(remarkRehype)
.use(rehypeStringify)
.process(await read('example.md'))
console.log(String(file))
```
…then running `node example.js` yields:
```html
<p>Mars is<br>
the fourth planet</p>
```
> 👉 **Note**: Without `remark-breaks`, youd get:
>
> ```html
> <p>Mars is
> the fourth planet</p>
> ```
## API
This package exports no identifiers.
The default export is [`remarkBreaks`][api-remark-breaks].
### `unified().use(remarkBreaks)`
Support hard breaks without needing spaces or escapes (turns enters into
`<br>`s).
###### Parameters
There are no parameters.
###### Returns
Transform ([`Transformer`][unified-transformer]).
## Syntax
This plugin looks for markdown line endings (`\r`, `\n`, and `\r\n`) preceded
by zero or more spaces and tabs.
## Syntax tree
This plugin adds mdast [`Break`][mdast-break] nodes to the syntax tree.
These are the same nodes that represent breaks with spaces or escapes.
## Types
This package is fully typed with [TypeScript][].
It exports no additional types.
## Compatibility
Projects maintained by the unified collective are compatible with maintained
versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line, `remark-breaks@^4`,
compatible with Node.js 16.
This plugin works with `unified` version 6+ and `remark` version 7+.
## Security
Use of `remark-breaks` does not involve **[rehype][]** (**[hast][]**) or user
content so there are no openings for [cross-site scripting (XSS)][wiki-xss]
attacks.
