remarkgfm

remarkgfm is a plugin for the remark Markdown processor that adds support for GitHub Flavored Markdown (GFM) features to the remark parsing and compilation pipeline. It is part of the unifiedjs ecosystem and is commonly used to enable GFM syntax when converting Markdown to an abstract syntax tree (AST) or to other output formats such as HTML.

Key features include support for GitHub Flavored Markdown syntax such as tables, strikethrough (text wrapped in tildes), task lists, and autolinks. It expands remark’s parsing rules to recognize and preserve these constructs so downstream tooling can render them correctly.

To use remarkgfm, install remark and remark-gfm, then add the plugin to the processing pipeline, for example by including remark().use(remarkGfm). The plugin integrates with other remark plugins such as remark-html or remark-stringify and fits into the standard remark workflow.

Remarkgfm is designed for projects that rely on GitHub-style Markdown. It is one of several official remark plugins maintained by the community and is compatible with the standard remark-parse workflow, allowing it to be combined with other plugins to customize output.

Limitations include that while it adds many GFM features, some GitHub-specific extensions or rendering nuances may require additional plugins or custom configurations. It primarily focuses on enabling GFM syntax within the remark pipeline.
