how can i import node modules in vanillajs project?

[cloudchamb3r]

When i wrote HelloWorld code on content script it works well.
But after importing few modules , npm run build emit Maximum call stack size exceeded error.
I found that just typing one line of import statement, such as import html2canvas from "html2canvas", on the top of the content script, it makes infinite recursion. (surely i'd installed node modules correctly)
Please tell me what i'm doing wrong
Thanks for reading ;)
