Note: the URL may be different if you've made adjustments via theHOST or PORT environment variables. Start your app by runningnpm start, and start debugging in VS Code by pressingF5or by clicking the green debug icon. You can now write code, set breakpoints, make changes to the code, a...
Visual Studio Code and WebStorm support debugging out of the box with Create React App. This enables you as a developer to write and debug your React code without leaving the editor, and most importantly it enables you to have a continuous development workflow, where context switching is minima...
parameters, a React component will always render the same output—no matter how many times it’s rendered, no matter who renders it, no matter where we place the output. Consequently, we don’t have to perform complex scaffolding to test React components, or track global variables and config...

Create React App is divided into two packages: create-react-appis a global command-line utility that you use to create new projects. react-scriptsis a development dependency in the generated projects (including this one). You almost never need to updatecreate-react-appitself: it delegates all...
Changing any environment variables will require you to restart the development server if it is running. These environment variables will be defined for you on process.env. For example, having an environment variable named REACT_APP_SECRET_CODE will be exposed in your JS as process.env.REACT_APP...
