remark is an ecosystem of plugins that work with markdown as structured data, specifically ASTs (abstract syntax trees). ASTs make it easy for programs to deal with markdown. We call those programs plugins. Plugins inspect and change trees. You can use the many existing plugins or you can make your own.
With this project and a plugin, you can turn markdown into HTML, modify syntax, or perform other transformations. remark builds upon [unified][github-unified], a core project that transforms content using ASTs, to provide markdown-specific functionality. [mdast][github-mdast] is the markdown AST that remark uses. This repository is a monorepo containing various packages related to markdown parsing and processing.
remark's core strength lies in its plugin system, allowing developers to extend markdown processing capabilities significantly. It supports a wide range of plugins for tasks like adding GitHub Flavored Markdown (GFM) support, linting, generating tables of contents, and transforming markdown to other formats like HTML. The focus on ASTs makes it easy to manipulate markdown content programmatically, enabling complex transformations and validations. It is widely used and actively maintained, boasting a large community and a rich ecosystem of plugins.
- Plugin Ecosystem: Over 150 plugins available for various tasks and transformations.
- AST-Based Processing: Utilizes Abstract Syntax Trees (ASTs) for programmatic markdown manipulation.
- Unified Integration: Seamlessly integrates with the unified framework for content transformation.
- Flexible Use Cases: Suitable for server-side processing, CLI tools, and client-side applications.
- CLI Tool: Provides a command-line interface for inspecting and formatting markdown files.
