Description

An easy-to-use mongodb library that returns promise objects

Installation

npm install easy-mongo-promise --save

Quick Start

require this packages and create a instance

const Client = require('easy-mongo-promise');

const db = new Client(url: 'mongodb://localhost:27017/users');

// or it could be like this
const db = new Client({
  url: 'mongodb://localhost',
  // If not, the default port will be configured
  prot: 27017,
  dbName: 'users'
});

find option

const Client = require('easy-mongo-promise');

const db = new Client(url: 'mongodb://localhost:27017/users');

// a collection must be specified before all operations
// with db.from('collection name')
// find option receive four parameters
/**
* [find option,return Promise]
* @param  {Object} findCondition [default: {}]
* @param  {Object} sortCondition [default: {}]
* @param  {Number} pageSize      [default: 0]
* @param  {Number} page          [default: 0]
* @return {Promise}              [description]
*/
db.from('info').find().then(res => {
  console.log(res);
});

Other operations are similar

// insert
db.from('info').insert(insertData).then(res => {
  console.log(res);
});

// update
// All you need to do is pass in the data you want to change
// Unwanted as {$set:{xx:xx}}
db.from('info').update(condition,data).then(res => {
  console.log(res);
});

//delete
db.from('info').delete(condition).then(res => {
  console.log(res);
});

Other unimplemented methods, can look like this

db.from('collection').__init()
.then(MongoClientObject => {
  // MongoClientObject.dbc represents the current collection
  MongoClientObject.dbc.find().sort({id:1}).toArray((err,res)=>{
    // close collection
    MongoClientObject.client.close();
    console.log(res);
  })
})
