    The code below should work for you:

    import mongoose, { Schema } from "mongoose";

const productSchema = new Schema(
    {
        title: String,
        description: String,
        stock: Number,
    },
    {
        timestamps: true, 
    }
);

export const Product = mongoose.model('Product', productSchema);

    Import this model when you want to use it:

    import { Product } from 'path/of/your/schema/'

const product = await Product.create({
  title: "test",
  description: "test description",
  stock: "50",
});
