Documentation (Quick start,Test the application front-end,1) I have a question about npm start. When I type the command npm start, I get an error:
npm ERR! Missing script: "start"
npm ERR!
npm ERR! Did you mean one of these?
npm ERR! npm star # Mark your favorite packages
npm ERR! npm stars # View packages marked as favorites
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR! npm run
there is no start element in the script of package.json. What do I need to specify here, like app.js for node.js express?
