MongoDB - simplest Schema

  1. Schema below 👇🏼 is really simplest, b/c it's more like recommendation, than require fields

    See the Pen 17 - Schema (for work with MongoDb) by Andrii (@imitator) on CodePen.

    Remember about reexport from folder in models/schemas/index.js

    const productSchema = require('./product.schema');
    module.exports = {
    productSchema,
    };
  2. Use Schema in Model in models/product.model.js
    const { model } = require('mongoose');
    const { productSchema } = require('./schemas');
    const Product = model('product', productSchema);
    module.exports = Product;

    Remember about reexport from models folder in models/index.js

    const Product = require('./product.model');
    module.exports = {
    Product,
    };

    Collection name (in example this is model("product", ...) write as a single noun.

  3. Also usually after schema added settings for mongoDb { versionKey: false, timestamps: true }, means don't add version of object, but add object created time & object updated time

    See the Pen 17_A__ Schema - with settings by Andrii (@imitator) on CodePen.

  4. Connection (binding) between collections has usually making with id. So if we would like to bind product collection with category, we add in schema field like

    See the Pen 17__B__Schema_binding_collections by Andrii (@imitator) on CodePen.

    So HTTP request will be with name, price & categoryID, actually we select one of the existing categories (means user selects on form).
    Check POST request making in this case.
