How should vue inside npm run build build?

  node.js, question

This is the first time to do automation. The official vue-cli is used. app.js produced by npm run dev has 1MB. After asking for npm run build and following it, I don’t know how to run. May I ask the Great God how to do it?

npm run devIt runs the project in development mode and can load some debugging modules such as hotload;;
npm run buildIs the project packaging command, after running this command will generate packaging files that can be online, at this time open the root directoryindex.htmlYou can see the effect of your project directly.
