how to Add my node_module, modules into package.json

Question

I have some module in my node_module folder but because I am amateur in nodejs, when I wanted to install theme, I forgot to use --save with npm i

Answer 1

Simply change into the directory containing node_modules, backup any existing package.json in there, then use npm init to re-create the package.json.

The generated package.json will include any modules that already exist within node_modules.

Sample run:

$ cd /my/project
$ mv package.json package.json.bak # Backup package.json
$ npm init                         # Recreate package.json with dependencies populated
