Where to add toastr package?

Need more clarification about the issue. Please considered:

• With dependecies

• No devDependecies

on my main project, I only want this on my package.json file:

"dependencies": {
        "simple-javascript-validtor": "^1.0.23",

that is, there should be no toastr entry on the main project's composer.json file.

Is there a way where the toastr package be defined inside this (simple-javascript-validator) package? So toastr prompt will still fire even it is not defined on the main project's composer.json file.

Hope I have cleared myself.
Thank you very much!
