This can be a local Node.js interpreter or a Node.js on Windows Subsystem for Linux. In this field, specify the Node.js interpreter to use. Learn more from the npm official website. In this field, specify the command-line arguments to execute a script with.

The list contains all the scripts defined within the scripts property in the package.json file. Learn more at npm documentation, under the section CLI Commands.įrom this drop-down list, choose the script to which the chosen command will be applied.

Here, the port is assigned to the number 4000.In this field, specify the package.json file to run the scripts from. If you need the app to run on some port, assign an environment variable named PORT to the desired port number. If you define an environment variable named IMG_PATH, it will be available in your component as _PATH. An environment variable is defined on process.env. env file are consumed in ReactJS as any local variable. gitignore, package.json and README.md are located.Įnvironment variables declared in the. env file in the root directory of your project, i.e., in the same directory where the files. Port number can also be set as an environment variable. Now if you run npm start, the app will start on port 2000.

'start': 'PORT=2000 react-scripts start', If you wish to run your React app on port number 2000, modify your package.json file as follows: It has the start key and its value needs to be prepended with PORT=N, where N is the assigned port number. If your app is created via npx create-react-app, you will find the scripts property in your package.json file. In Windows, the command is slightly different As an example, here we change the port number to 5000. In ReactJS, the easiest way to alter the port number is by setting an environment variable named PORT to the desired number via the terminal.
