Create One To One Relationship MongoDB With NodeJS and Mongoose

Data Base Input

Change value of key database on server.js

Example:

For Brand Table :
{
    name: "Microsoft"
}

For Device Table :

{
    name: "Surface Book"
    storage: "256GB"
    color: "Grey"
    code: 512GB // key code is automatically generated
    brand: {name: "Microsoft"} // automatically by reference on Brand Table
}

So you just change key name on Brand table, and change keys name, storage, color on Device table.

Run Code

$ cd
$ npm run dev
