Require dev dependencies

[Zain-ul-din]

Proposal

Our framework requires some dev-dependent packages in order to work correctly. Our CLI should check the required packages.

• check all required packages in package.json.
• throw a helpful error on the package not found.

Basic Overview

const requiredPkgs = ['typescript', 'babel']

// package.json ✔ fine
{
 "devDependencies": {
    "typescript": "^5.0.1",
    "babel": "^1.0.1"
 }
}

// package.json ❌ error
/*  `require typescript`  */
{
 "devDependencies": {
    "babel": "^1.0.1"
 }
}
