const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const BlogSchema = new Schema({
  title:{
    type:String,
  }
  description:{
    type:String,
  },
  category_id:{
    type:Schema.Types.ObjectId,
    ref:"ref_to_your_category_model"
  },
  order:{
    type:Number,

  }
});
//make model with your schema
const Blog = mongoose.model("Blog", BlogSchema);

Import the package

//. for Maximun Order Number of your documents
const { MAX_DOCUMENT_ORDER } = require("mongoose-order-manager");

/*
@param model_name : your model name
@param query: query for your documents you can pass empty object if you want to get maximun order number for all documents
@ order_field: order field name e.g order
*/

// error : true if there is an error
// error_message : error message
// max_order : maximun order number

const { error, error_message, max_order } = await MAX_DOCUMENT_ORDER(
  Blog, //model name
  {}, // query object empty if you want to get maximun order number for all documents
  "order"
);

// if you want to get maximun order number for documents with specific specific query you can pass query object as second parameter

let query_obj = {
  category_id: req.body.category_id, // category_id is the field name of your category
};

const { error, error_message, max_order } = await MAX_DOCUMENT_ORDER(
  Blog, //model name
  query_obj, // query object
  "order" // order field name
);

if (error) {
  // handle error
  // if you are using express you can send error message as response
  return res.status(500).json({
    error: true,
    message: error_message,
  });
}

// if there is no error you can get maximun order number
let new_blog = new Blog({
  title: req.body.title,
  description: req.body.description,
  order: max_order + 1, // you can set order of new document as maximun order number + 1
});

await new_blog.save();

// Every time you create a new document you can set order of new document as maximun order number + 1

Update Order of a specific document with respect to other documents for higher order number or lower order number

const { UPDATE_DOCUMENT_ORDER } = require("mongoose-order-manager");

let _id = document._id; // _id of document you want to update order
let current_order = Number(req.body.current_order); // current order of the document
let past_order = Number(document.order); // past order of the document

var { error, error_message } = await UPDATE_DOCUMENT_ORDER(
  _id, // id of the document you want to update
  current_order, // current order of the document
  past_order, // past order of the document
  Blog, // model name
  {}, // query object empty if you want to update order of all documents not according to specific query
  order_field // order field name
);

// if you want to update order of documents with specific query you can pass query object as fourth parameter

let query_obj = {
  category_id: document.category_id, // category_id is the field name of your category
};

var { error, error_message } = await UPDATE_DOCUMENT_ORDER(
  _id, // id of the document you want to update
  current_order, // current order of the document
  past_order, // past order of the document
  modelName, // model name
  query_obj, // query object (optional)
  order_field // order field name
);

if (error) {
  // handle error
  // if you are using express you can send error message as response
  return res.status(500).json({
    error: true,
    message: error_message,
  });
}

const {
  CHANGE_DOCUMENT_ORDER_EXCEPT_DELETED,

var { error, error_message } = await CHANGE_DOCUMENT_ORDER_EXCEPT_DELETED(
  _id, // id of the document you want to delete
  order, // order of the document you want to delete
  modelName, // model name
  {}, // query object empty if you want to change order of all documents not according to specific query
  order_field // order field name
);

// if you want to change order of documents with specific query you can pass query object

let query_obj = {
  category_id: document.category_id, // category_id is the field name of your category
};

var { error, error_message } = await CHANGE_DOCUMENT_ORDER_EXCEPT_DELETED(
  _id, // id of the document you want to delete
  order, // order of the document you want to delete
  modelName, // model name
  query_obj, // query object
  order_field // order field name
);

if (error) {
  // handle error
  // if you are using express you can send error message as response
