Template

Man is the man page for the mongodb model. If you are not building a cli application, then you most likely do not need it. Man is a duplex stream, specifically a Transform stream with some functionalities added. Primarily, it uses full power of the NodeJs Transform Stream API. In other words, everything you can do with NodeJs Transform API you can do with cli! Cli is centrally very highly event driven. Its common use is by extension or by using object destruction to get the instance methods needed.

Installation

$ yarn add @mongodb-model/template

or

$ npm i @mongodb-model/template

Simple Usage Examples

Making api request (http request)

const CLI = require('@mongodb-model/template');
const cli = new CLI();
cli.apiGet(); //base.apiGet(your api endpoint)
cli.on('apiGet', data => console.log(data));
cli.on('apiGet-error', error => console.error(error));
 

By extension

class MyWonderfulClass extends require('@mongodb-model/template') {

    constructor(...arrayOfObjects) {

    super({ objectMode: true, encoding: "utf-8", autoDestroy: true });

    arrayOfObjects.forEach(option => {
        if(Object.keys(option).length > 0){
            Object.keys(option).forEach((key) => { if(!this[key]) this[key] = option[key];})
        }
    });

    this.autobind(MyWonderfulClass);
    this.autoinvoker(MyWonderfulClass);
    this.setMaxListeners(Infinity);
  }
};

Schema template creation example: userSchemaTemplate

const Template = require('@mongodb-model/template');

const {schema} = new Template

const userSchemaTemplate = schema({name: 'UserSchema', type: 'object'});

// The resulting userSchemaTemplate contains: 

'use strict';
/*
|--------------------------------------------------------------------------
| UserSchema Schema
|--------------------------------------------------------------------------
|
| Here we you may add more options (keys) to you schema.
|
|
*/
const Schema  = require('@mongodb-model/db-schema');

const {makeSchema}  = new Schema;

 module.exports = makeSchema("UserSchema",{

  property: "string|min:2|max:10",

 }, "object") ;

Model template creation example: userModelTemplate

const Template = require('@mongodb-model/template');

const {model} = new Template

const userModelTemplate = model({model: 'User', collection: 'users'});

// The resulting userModelTemplate contains: 


'use strict';
/*
|--------------------------------------------------------------------------------
| User Model
|--------------------------------------------------------------------------------
|
| User extends the base model (Model) class and thus has everything
| the base model has including all the basic CRUD methods or operations.
