remarkhtml

Remarkhtml, more commonly seen as remark-html, is a plugin for the Remark processor in the UnifiedJS ecosystem. It converts Markdown content into HTML by transforming the Markdown abstract syntax tree into HTML that can be emitted as a string or integrated into a larger processing pipeline. As a plugin, it is used inside a remark processing chain rather than as a standalone formatter.

In practice, remark-html is used to render Markdown to HTML in Node.js environments, such as static site generators, content management workflows, or server-side rendering tasks. It fits into the broader remark and unified toolchains, where multiple plugins can be composed to parse, transform, and output content. The typical workflow involves creating a remark processor and adding the html plugin, then processing Markdown input to obtain HTML output.

Usage generally involves installing the package and wiring it into a processor. For example, after installation, you would create a processor with remark().use(require('remark-html')) and run process or processSync on Markdown content to produce an HTML string. The resulting HTML reflects standard Markdown rendering, with headings, paragraphs, lists, links, and other elements converted to their HTML equivalents.

Options and extensions: remark-html accepts configuration that influences how HTML is emitted, and for security or customization concerns, developers often combine it with additional plugins such as rehype-sanitize to control or sanitize the output. As with other plugins in the Unified ecosystem, it can be extended or replaced in larger processing pipelines.
