Separate js code from sfc

[Lee-42]

Description

I try to separate the js logic of the sfc file into a file, and then import it through src But there is a problem with updating the page This works fine with webpack

Suggested solution

Sometimes the js code logic is too long, or the js code is generated by other compilers, I don’t know how I should implement it
