vite-plugin-markdown

This plugin just for my purpose only, feel free to develop it up. Very inspired from snowpack-plugin-markdown. But, I add little different option.

Installation

npm i @dansvel/vite-plugin-markdown --save-dev

Then add it to your Vite config

Example: SvelteKit

svelte.config.js

import markdown from '@dansvel/vite-plugin-markdown'

/** @type {import('@sveltejs/kit').Config} */
const config = {
  // some preprocessor maybe
  kit: {
  target: '#svelte',
    vite: () => ({
      plugins: [
        markdown(),
      ],
    })
  }
};

export default config;

Options

Function of the plugin is something like this

{
    markedOptions?: marked.options;
    withOrigin?: boolean;
}

Example

marked.options.js

import hljs from 'highlight.js'

const highlight = (code, lang) => {
  lang = lang && hljs.getLanguage(lang) ? lang : 'plaintext'
  return hljs.highlight(code, {language: lang}).value
}


export default { highlight }

See https://marked.js.org/using_advanced#options for more marked options

svelte.config.js

import markdown from '@dansvel/vite-plugin-markdown'
import markedOptions from './marked.config.js'

const config = {
  kit: {
    target: '#svelte',
    vite: () => ({
      plugins: [
        markdown({ markedOptions, withOrigin: true })
      ]
    })
  }
};

export default config;

Usage

Attributes can be added to the top the file in YAML format:

---
title: Hello World!
date: 2020-01-01
---

i am from **markdown**

Single file

The attributes will be available when imported:

import content from './path/to/some/file.md'

// content.body -> markdown converted to html
// content.attributes -> from attributes frontmatter // something like{ title: "hello world", author: "dansvel"}
// content.markdown -> original markdown (if `options.withOrigin` set to `true`)

or

import { attributes, body } from './path/to/some/file.md'

Multiple file

synchronous example

// example from index.svelte
<script>
  import { page } from '$app/stores';

  const files = import.meta.globEager('../posts/*.md')
  const posts = []

  for (const path in contents) {
    const { attributes } = files[path].default
    posts.push(attributes)
  }
</script>

asynchronous example

// example from index.svelte
<script context="module">
  export const load = async () => {
    const files = import.meta.glob('../posts/*.md')
    const posts = []

    for (const path in files) {
      const { attributes } = (await files[path]()).default
      posts.push(attributes)
    }

    return { props : { posts } }
  }
</script>
