In Next.js, “props” is a common abbreviation for “properties,” and it’s a fundamental concept in React, the library on which Next.js is built. “Props” are a way to pass data from a parent component to a child component in a React application. In Next.js, which is a framework for building React applications, you use props to send data from a page component to other components, including child components.
Here’s how props work in Next.js:
- Passing Data: Props allow you to pass data from a parent component (usually a page component in the context of Next.js) to a child component.
- Read-Only: Props are read-only. Once you pass data to a child component via props, that child component cannot modify the data. It’s meant to be a one-way communication channel from parent to child.
- Customization: Props are used to customize the behavior or appearance of a component. For example, you might pass a title or content to a child component to customize what it displays.
- Functional Components: In functional components (which are the most common way of creating components in modern React), props are typically received as an argument to the function, and you can access the data using
props.propertyName.
