Error [ERR_MODULE_NOT_FOUND]: Cannot find module

When working with Node.js, you might sometimes see this confusing error:

Error [ERR_MODULE_NOT_FOUND]: Cannot find module

✅ The Solution: 

If you want to use import instead of require you need to add module part to your package.json.
To tell Node.js that you are using ES Modules syntax (import/export),

just add this line to your package.json:

{
  "type": "module"
}

Because by default, Node.js looks for CommonJS files using require(), not import. 

📦 The Problem: Node.js Module System

In Node.js, there are two types of modules:

• CommonJS (CJS) – uses require()
• ES Modules (ESM) – uses import

By default, Node.js assumes you are using CommonJS unless you tell it otherwise.

This is the error I faced.

This is the fix
