For a school project, I generated a phoenix project with the --no-webpack option. Now we needed to extend our project with javascript and webpack. The problem is I don't have an assets folder and I'm wondering if there's still a way to generate it or another possible fix. I already tried generating another project and copy pasting my files between them but this gave me errors in different files.
Generating another project is a way to go, but you could let git to do the merge for you.
Generate a project with the same name in other directory and then merge with allow-unrelated-histories option:
git merge ../other-folder/same-project-name --allow-unrelated-histories
Then you will need to resolve conflicts on some files, but they are easy to resolve.
