Debugging in developing chrome extensions

I"m developing a chrome plug-in right now, but I don"t know how to debug it! Not the kind of debugging that examines elements, but as usual in the development of web applications, you can see the effect of the page without packaging.

the result of running directly is that some API interfaces prompt an error. Now you can only modify the page and package it to see the effect

I want to develop as quickly as possible. I can see the effect while modifying the code

you can't see the effect while modifying it (maybe I don't know.)
but if you check developer mode , you don't need to pack the import folder every time
