VUE, why does a hello world package JS have 1MB?

  node.js, question

As shown in the figure, the loading of web pages is very slow, and it is found that JS has 1MB. what is this situation? it is packaged through the command line tool (vue-cli) of the official website. why is this? I think someone else’s is only about 140KB.

This is a runtime file, not an actual packaged file, please npm run build to see dist actual file size.
