Welcome Users, Don't repeat yourself, use reusable code :) Always happy to help you,

Happy Coding ♥

Installation

$ npm install mongoose-utils-helper

Getting Started

Importing

// Using Node.js `require()`

const {
    connection, //connection function
    createModel, //function for creating mongodb model
    common_helper, //common_helper for CRUD operation
    commonFuns, // common functions
    mongoose  // mongoose package object
} = require('mongoose-utils-helper');

// Using ES6 imports
import { connection, createModel, common_helper, commonFuns, mongoose } from  'mongoose-utils-helper';

Connecting to MongoDB

First, we need to define a connection. If your app uses only one database, you should use connection() function.

connection() takes two arguments First mongodb:// URI, or the object with following properties username password, hostname, port and second agrument is to disable default console when connection is connected(default value is true).

Example:

// Using Node.js `require()`
const { connection } = require('mongoose-utils-helper');
// Using ES6 imports
import { connection } from  'mongoose-utils-helper';

let  dbUri = "mongodb://localhost/test";

const  db = connection(dbUri);

connection() function return the database connection Object.

Defining a Model

Models are defined through the createModel() interface.

Example:

import { createModel } from  'mongoose-utils-helper';
**Important!** `createModel(schema,collectionName)`  interface  required  two  arguments,

var MyModel = createModel({
    body : { type: String, default: "" },
    date : { type: Date, default: Date.now },
}, "my_model");

Once we have our model, we can then instantiate it, and save it:

MyModel.find({}, function (err, docs) {
// docs.forEach
});

You can also findOne, findById, update, etc. For more details check out the docs.

Using common_helper

Basic insert, insertMany, update, softDelete, delete, find, findOne and count operations using common_helper.xxx(Model,condition) Object.

Example:

// Using Node.js `require()`

const { common_helper } = require('mongoose-utils-helper');
// Using ES6 imports
import { common_helper } from  'mongoose-utils-helper';

let  condition = { name :  "Amitu" };
let  data = await  common_helper.find(MyModel, condition);

//output response:
{
    status : 1, //status code (1 for success 0 for fail)
    message : "Data found", // Response message
    data :<operation  output> }; // can be object, array or string
}

Using commonFuns

Example:

// Using Node.js `require()`
const { commonFuns } = require('mongoose-utils-helper');

// Using ES6 imports
import { commonFuns } from  'mongoose-utils-helper';

let  mongodbId = "5ac343820e617c07555c47f0"

let  convertedMongoObjId = await  commonFuns.convertMongoId(mongodbId);
let  convertedMongoObjId = await  commonFuns.mongooseCheckValid(mongodbId);
