Dimer markdown is an opinionated markdown processor built on top of remark with following features and goals.

  • Implements the markdown directives proposal to extend the markdown native capabilities
  • Introduces the concept of macros that builds up on top of directives
  • Selectively allow/dis-allow HTML inside Markdown
  • Register listeners to hook into Markdown compilation phase
  • First class support for frontmatter, generating toc and excerpt from the doc summary


Install the package from npm registry as follows:

npm i @dimerapp/markdown

# yarn
yarn add @dimerapp/markdown

And import the package to process the markdown files.

import { MarkdownFile } from '@dimerapp/markdown'

const markdownContents = `
# Hello world

This is a markdown doc with some GFM syntax

- [ ] Todo 1
- [ ] Todo 2`

const md = new MarkdownFile(markdownContents)
const ast = await md.process()

Generating HTML

The package encourages using AST vs directly generating the HTML from the markdown. Using AST let you bring your own frontend layer. It is like creating a JSON API and then using Vue or React to create webpages.

However, if also ship with a helper function to convert the markdown file instance to HTML.

import { MarkdownFile, toHTML } from '@dimerapp/markdown'

const md = new MarkdownFile(contents)
await md.process()

const { contents, summary, toc, excerpt } = toHTML(md)
  • contents is the HTML representation of the markdown file contents
  • summary is the HTML representation of the file summary. You can also define summary using frontmatter.
  • toc is the HTML representation of the table of contents. Available only when generateToc option was used.
  • excerpt is the plain text version of summary. Helpful for SEO


You can pass the following options when creating a new instance of the MarkdownFile.

import { MarkdownFile } from '@dimerapp/markdown'

const md = new MarkdownFile(contents, {
  generateToc?: boolean
  allowHtml?: boolean
  filePath?: string
  enableDirectives?: boolean
  collectAssets?: boolean
  • generateToc: Define whether you want to generate the table of contents or not. Defaults to false.
  • allowHtml: Control whether you want to allow HTML inside Markdown or not. Defaults to false.
  • filePath: Optionally you can attach the absolute file path to the mdFile instance.
  • enableDirectives: Enable support for the directives proposal. Defaults to false.
  • collectAssets: Decide if you want us to collect the asset links referenced inside your markdown file. Currently image links are only collected.
