How to make package.json from package-lock.json file

Question

I am learning backend side using node.js and express framework. I added modules by npm install *** --save. After several hours i noticed that my project didn't contain package.json file.

There's only package-lock.json

I am now trying to add test command to use nodemon. Like dev: nodemon app.js. but there's no such part in package-lock.json file.

I don't want to start from scratch again.

run `npm init` and answer the questions to create a package.json — Roland Starke, Apr 18 '19 at 13:29
will it contain all dependencies i have already installed? @Roland Starke — Derek Jin, Apr 18 '19 at 13:33
@DanKonus Yes, `npm init` will add the already installed node modules to `package.json`. — Aaron Beall, Apr 18 '19 at 13:44
you can use `npm init -y` to generate it without user prompt — Ihor Sakailiuk, Apr 18 '19 at 14:22

package-lock.json: records the exact version of each installed package which allows you to re-install them. Future installs will be able to build an identical dependency tree.

package.json: records the minimum version you app needs. If you update the versions of a particular package, the change is not going to be reflected here.
