Learn React Portal In 12 Minutes By Building A Modal
IMPORTANT:
Full React Course:
React is a complex library to use and the fact that everything is nested inside a component can make certain tasks much more difficult. One of those tasks is rendering popups and modals. It doesn't make sense for them to be rendered inside a component, but you need to access them inside a component. This would lead to a impossible problem to solve, but React thought of this for you. Portals are a way for you to render an element somewhere else while still having access to it in the component you are working on. They are a bit complex at first, though, so in this video I breakdown React portals step by step.
