remark-cli

What is remark-cli?

remark-cli is a command-line interface for the remark processor, which is a tool for processing Markdown content. It allows you to lint, format, and transform Markdown files using plugins.

What are remark-cli's main functionalities?

Linting Markdown files

This command lints all Markdown files in the current directory using the recommended linting rules provided by the 'remark-preset-lint-recommended' plugin.

remark . --use remark-preset-lint-recommended

Formatting Markdown files

This command formats all Markdown files in the current directory and writes the changes back to the files. The '--output' flag specifies that the changes should be saved.

remark . --output

Transforming Markdown files with plugins

This command transforms all Markdown files in the current directory to HTML using the 'remark-html' plugin and writes the changes back to the files.

remark . --use remark-html --output

Security

As Markdown is sometimes used for HTML, and improper use of HTML can open you up to a cross-site scripting (XSS) attack, use of remark can also be unsafe. When going to HTML, use remark in combination with the rehype ecosystem, and use rehype-sanitize to make the tree safe.

Use of remark plugins could also open you up to other attacks. Carefully assess each plugin and the risks involved in using them.
