'Visual Studio Node NPM sequelize / tedious dependencies (not listed in package.json)

I am trying to install sequelize and then tedious. I run npm install sequelize, for example. After installing, the Solution Explorer lists a copious number of packages that are suffixed by (not listed in package.json). I have never seen this before and don't know if this is a corrupt install, or whether it is okay. It doesn't look pretty. I have tried an npm ci and npm update and neither fixed the issue. Should I care? Or just collapse that folder and keep going?

Solution 1:[1]

it's a normal, after install any lib. what happens is that the sequelize module has its own dependencies, so it will also install them. Remember that every time a lib is installed, it will certainly install other libs and in the end, we will have n folders.

for example:

npm i express

several folders with express dependencies will be created

express dependencies
