Y0data services

MongoDB-style client for connecting to Y0Data worker server Your data will save in servers y0data, so no disk will take from your server

install y0data

npm install y0data

Connect Database

const Database = require('y0data');

// Create connection with host, port, databaseId, username, password
const db = new Database(
  'localhost',  // host
  5001,         // port
  'f9b07fbe-7c8d-4f9d-9028-ebec6b3b2eea',  // databaseId
  'yousuf',     // username
  '41371755aa'  // password
);

events

db.on('authenticated', async ()=>{
  console.log(`DataBase Ready`)
  // Now you can use database methods
})

db.on('error', (err)=>{  
  console.log(`Error: ` + err)
})

db.on('connected', ()=>{
  console.log(`Connected to server`)
})

db.on('disconnected', ()=>{
  console.log(`Disconnected from server`)
})

setup collection

let customersDB = db.model('Customer', {}, 'customers')
// Now you can use customersDB methods

functions

Create

let data = await customersDB.insertOne({"money": 51}) // example output → '[Accepted Data]'
let data = await customersDB.insertOne({"_id": "123", "money": 5}) // example output → '{Accepted Data} / null'
let data = await customersDB.insertMany([{"money": 51}, {"money": 9}]) // example output → '[Accepted Data]'
/*
Data will be serialized to BSON format automatically
*/

find data

let options = {
  money: {$gte: 10}, // Get Users have money greater than or equal to 10
  age: {$gt: 50} // get Users have age greater than 50
}

let data = await customersDB.find(options) // example output → 'Array'
let data = await customersDB.find(options, {limit: 20}) // (Get Only 20 data) example output → 'Array'
let data = await customersDB.find(options, {skip: 20}) // (Skip first 20) example output → 'Array'
let data = await customersDB.find(options, {limit: 20, skip: 10}) // (Skip 10 and limit 20) example output → 'Array'

let data = await customersDB.findOne(options) // example output → 'Object/Null'
let data = await customersDB.findOne(options, {skip: 20}) // (Skip first 20) example output → 'Object/Null'
let data = await customersDB.findById('123') // (Find by ID) example output → 'Object/Null'

Update Data

let options = {
  money: {$gte: 10}, // Get Users have money greater than or equal to 10
  _id: {$in: ['123', '1234']} // get Users with IDs in array
}

let new_values = {
  $inc: {money: 50}, // Add money you can also do -50 to remove

  $push: {arr: ["1"]}, // add in array items 
  $push: {arr: "1"}, // add in array item

  $pull: {arr: ["1"]}, // delete from array items
  $pull: {arr: "1"} // delete from array item
}

let data = await customersDB.updateOne(options, new_values) // example output → 'true/false' 

let data = await customersDB.updateMany(options, new_values); // example output → 'true/false' (if update one only will return true always)

Delete Data

let options = {
  money: {$gte: 10}, // Get Users have money greater than or equal to 10
  _id: {$in: ['123', '1234']} // get Users with IDs in array
}

let data = await customersDB.deleteOne(options) // example output → 'true/false'

let data = await customersDB.deleteMany(options); // example output → 'true/false' (if update one only will return true always)

Other functions will support you

let options = {
  money: {$gte: 10}, // Get Users have money greater than or equal to 10
}

let data = await customersDB.countDocuments(options) // example output → 'Number'

Disconnect

db.disconnect() // Close connection to server
