Unified

Introduction

is a friendly interface backed by an ecosystem of plugins built for creating and manipulating content.
takes data in different formats, and translate them into structured data¹
usified is a chain of processes, with many plugins you can connect with
no manual parsing or syntax handling

Parse: any input needs to be parsed to a workable format (mdast, hast...)²
Transform: all the magic happens here. here's where all the plugins transform the input depending on the order too.
Stringify: take the formatted content and stringify it to Markdown, HTML or prose.

check repo for the example: https://github.com/horacioh/unified-intro
in this example we will learn how to turn Markdown into HTML.
for that we need a Markdown parser (remark-parse) and an HTML stringifier (rehype-stringify)
to transform between Markdown and HTML we need remark-rehype
to glue all and stream it, we are going to use unified.
you have a bunch of plugins available to work with content (that's COOL)
Note that remark plugins work on a Markdown tree, and rehype plugins work on an HTML tree. It’s important that you place your .use calls in the correct places.
I use the remark-heading-id plugin to enable custom heading links on the HTML result (❤️)

are all transformation following the same structure? (HTML -> structure1 ; MD -> structure2 ; structure1 === structure 2 ?)↩
