ReadMe has introduced custom components built using JSX and Tailwind to enable the creation of interactive and dynamic API documentation, moving beyond the static nature of traditional Markdown. These components, which can include elements like faux Terminal windows, comparison matrices, and progress bars, are designed to be reusable, customizable, and easily integrated into documentation projects. By leveraging MDX, users can embed JSX directly within markdown content, enhancing the interactivity of their documentation. The built-in support for Tailwind, a rapidly growing utility-first CSS framework, allows for effortless styling of components using utility classes, providing thousands of compatible components out of the box. This approach ensures that components are lightweight, portable, and easy to share or move between projects, fostering a collaborative development environment. Additionally, ReadMe offers a marketplace for community-built components and provides resources and support for users to create and customize their components.
