Update package.json in several places after “npm i”

Question

I want to be able to detect any new package installed according to my package.json file, so when ever I do "npm i", it will automatically added to another section on my package.json file.

For example, if I do "npm i axios", It will update in 2 places on my package.json file: on "dependencies" as usual, and on new section I created: "extDependencies".

Is there any way to detect any new installed packages?

Check this out: npm-scripts documentation

If you want to run a specific script at a specific lifecycle event for ALL packages, then you can use a hook script.

Place an executable file at node_modules/.hooks/{eventname}, and it'll get run for all packages when they are going through that point in the package lifecycle for any packages installed in that root.

Hook scripts are run exactly the same way as package.json scripts. That is, they are in a separate child process, with the env described above.

You could use this to create a postinstall script (bash, python, node.js, etc) that reads the npm_package_name and npm_package_version environment variables and then use those to update the package.json.
