# Setup React This lab requires `React` and `create-react-app` to build the app. ## What is React? React is a UI JavaScript library by Facebook for building efficient user interfaces and Single Page Applications. With React, you can build reusable frontend UI components in your app. ## Install create-react-app Facebook has a command line tool, `create-react-app` that can scaffold a progressive web app out of the box in less than a minute. Let's install the `create-react-app` tool globally using npm: ``` npm install -g create-react-app ``` This will install the `create-react-app` command line tool, which will make it easy to initialize your app with React. ## Provision your app Run the `create-react-app` command via the command line. ``` create-react-app miniflix ``` Navigate to the **miniflix** directory via the command line. ``` cd miniflix ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
