Usage

CJS

const { Schema, Model } = require('suyotechdb');

const userSchema = new Schema({
  name: { type: String, required: true,default : "" },
  email: { type: String, required: true, default: "" },
  age: { type: Number, default: 18 },
});

// define database path where to save files
const database_path  = "./db"; 

const User =  new Model('users',database_path, userSchema);

ESM

import { Schema, Model } from 'suyotechdb' ;

const userSchema = new Schema({
  name: { type: String, required: true,default : "" },
  email: { type: String, required: true, default: "" },
  age: { type: Number, default: 18 },
});

//define database path where to save files
const database_path  = "./db"

const userModel =  new Model('users',databse_path, userSchema);

CRUD Operations

createOne

Use the createOne function to add a new item

userModel.createOne({
  name : "suyog",
  email : "test@domain.com",
  age : 20,
})

insertMany

Use the insertMany function to add a new item

const users = [
{
  name : "suyog",
  email : "test@domain.com",
  age : 20,
},
{
    name : "user2",
  email : "email@domain.com",
  age : 26,
}
]

userModel.insertMany(users)

findOne

Use the findOne function to find one document

const user = userModel.findOne({name : "suyog"})
console.log(user); // { id: ksldf09-ksdjflsd-sdkfsld, name: 'suyog',email : "suyog@gmail.com",age : 20 } 

findAndDeleteOne

Use the findAndDeleteOne to find first matching document and delelte.

const query = {name : "suyog"}
const result = userModel.findAndDeleteOne(query)
console.log(result) // deleted successfully

findOneAndUpdate

Use the findOneAndUpdate to find first matching docuemnt and update.

const query = {name : "suyog"}
cosnt updateData = {age : 30}
const result = userModel.findAndDeleteOne(query,updateData)
console.log(result) // updated successully

udpateMany

Use the udpateMany to find first matching docuemnt and update.

const query = {name : "suyog"}
cosnt updateData = {age : 30}
const result = userModel.updateMany(query,updateData)
console.log(result) // updated successully

deleteMany

Use the deleteMany to find first matching docuemnt and update.

const query = {name : "suyog"};
const result = userModel.deleteMany(query);
console.log(result) // updated successully

find

This is special query which can use many different chained operations

• It supports following operation for query operators
  • $in - Finds value in field
  • $nin - Check not in values
  • $eq - Equals to
  • $ne - Not equals to
  • $gte - Greater Than
  • $lte - Less Than
• Chained Functions
  • sort - Sort by given query
  • limit - Limits Documents
  • skip - Skips Documents
  • select - Select or deselect based value 0 or 1 respectively
  • distinct - Distinct Field Values
  • count - Count of find query result
  • exec - Function need after find or chained to return data.

const query  = {age  :{$gte: 10}}
const result = userModel
          .find(query)
          .sort({name : 1})
          .limit(5)
          .skip(2)
          .select({name : 1})
          .exec()
