What is this?

This package is a remark plugin.

When should I use this?

If you want to resolve paths relative to the current file.

All url parameters of all nodes are resolved, as well as all string-valued attributes of MDX flow elements and directives, that look like a relative path, i.e. that start with ./ or ../.

You can further specifiy, whether you want to normalize a path only, if the normalized target exists, see Options for details.

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install remark-normalize-paths

Use

import remarkDirective from 'remark-directive';
import remarkMdx from 'remark-mdx';
import remarkNormalizePaths from 'remark-normalize-paths';
import remarkParse from 'remark-parse';
import { unified } from 'unified';

const processor = unified()
  .use(remarkParse)
  .use(remarkDirective)
  .use(remarkNormalizePaths, { exclude: ["link", "<CustomComponent>"] });

This markdown in the file /workspace/content/index.md:

![](./picture.jpg)

[Read more](./all/index.html)

<img src="../other-picture.png" />

::Quote[MDX is great]{author="Me" avatar="./me.jpg" .xxl}

<CustomComponent ref="./input.txt" />

would yield the following paths:

• ./picture.jpg -> /workspace/content/picture.jpg
• ./all/index.html -> ./all/index.html, because links are excluded in the extensions configuration
• ../other-picture.png -> /workspace/other-picture.png
• ./me.jpg -> /workspace/content/me.jpg

Options

rebase?: string

Path to use as new base path and make all resulting paths relative to this path.

Default is undefined, i.e. resulting paths will be absolute.

checkExistence?: boolean

Normalize path only, if normalized path exists, leave untouched otherwise.

Default is true.

include?: string[]

List of MDX element types or JSX tags (if put in angle brackets, e.g. <img>)to include during path normalization (only the named types will be included).

Default is undefined, i.e. all MDX element types will be included.

exclude?: string[]

List of MDX element types or JSX tags (if put in angle brackets, e.g. <img>) to exclude during path normalization. E.g. ['link', '<a>'] to exclude markdown links and JSX anchor tags.

Default is undefined, i.e. no MDX element types will be excluded.
