How it work

MongoDB context

• using:

import { connectMongoDb } from "krc-mongodb";

await connectMongoDb();

• output: MongoDB connected...

Repository pattern

• Define model schema:

import { Schema } from "mongoose";

const CategorySchema: Schema = new Schema({
  categoryId: {
    type: String,
    required: true,
  },
  parentId: {
    type: String,
  },
  name: {
    type: String,
    required: true,
  },
  context: {
    type: String,
    required: true,
  },
  active: {
    type: Boolean,
  },
  createdBy: {
    type: String,
  },
  updatedBy: {
    type: String,
  },
  createdTime: {
    type: Date,
  },
  updatedTime: {
    type: Date,
  },
});

• Define model instance:

const Category = model("categories", CategorySchema);

• Define entity interface:

import { IDocument } from "krc-mongodb";

interface ICategory extends IDocument<string> {
  categoryId: string;
  parentId: string;
  name: string;
  context: string;
  active: boolean;
  createdBy: string;
  updatedBy: string;
  createdTime: Date;
  updatedTime: Date;
}

• Declare repository into service to query:

import { Repository } from "krc-mongodb";

_categoryRepository = Repository<string, ICategory>(Category);

const allCategories = _categoryRepository.find({});
