React-cool-portal: What it is and how to use it

React portals, introduced in version 16.0, address the limitation of rendering elements outside the root node, which is typically restricted under a single 'div' with an ID of 'root'. React portals allow elements such as modals or tooltips to be rendered outside this root, enhancing flexibility. This functionality became more streamlined with React Hooks in version 16.8, enabling reusable stateful logic without altering the component hierarchy. The blog post explores a Hooks-based library called react-cool-portal, which simplifies the creation of portals. This library offers features like automatic removal of unused portal containers, TypeScript support, and server-side rendering compatibility. It allows for configuration options such as default visibility and event handlers for showing or hiding portals. The post demonstrates building an animated modal using react-cool-portal, showcasing how to implement state and animation logic efficiently with React. Additionally, it highlights how react-cool-portal can be used to enhance code reusability through custom Hooks, ultimately providing a more manageable and sophisticated way to handle UI components in React applications.
