Installing react, react-dom, and react-scripts with cra-template... added 1395 packages in 1m Initialized a git repository. Installing template dependencies using npm... added 71 packages in 4s Removing template package using npm... removed 1 package in 2s Created git commit. Success! Created todolist at E:\workspace\demo\p4\todolist Inside that directory, you can run several commands: npm start Starts the development server. npm run build Bundles the app into static files for production. npm test Starts the test runner. npm run eject Removes this tool and copies build dependencies, configuration files and scripts into the app directory. If you do this, you can’t go back! We suggest that you begin by typing: cd todolist npm start Happy hacking!
