@jokio/monzo

Library will help to work with mongodb

Features

✅ Stores _id: ObjectId field, but wraps it to the id: string

✅ Documents have version: number out of the box, and its increased by 1 every time you call update

✅ Every document has createdAt and updatedAt props

✅ Soft Delete & Hard Delete ability for documents

How to use

1. Declare data structure

import { DocumentBase } from '@jokio/monzo'

export interface User extends DocumentBase {
	email: string
	passwordHash: string
	fullname?: string
}

2. Create repository object for declared type

import { getRepository } from '@jokio/monzo'

const connectionString = `mongodb://mongo:mongo@localhost:27017/test?authSource=admin`
const client = new MongoClient(connectionString, { useNewUrlParser: true })

await client.connect()

const db = client.db()

const users = getRepository<User>(db, 'users')

3. Use repository object

const user = await users.create({
	email: '[email protected]',
	passwordHash: 'strong-hash',
})


const { id, version } = user

const updatedUser = await users.update(
	{ id, version },
	{
		email: '[email protected]',
	},
)

Performance Cost

Library calls _id.toHexString() for all retrieved items to have id: string and make developers life easier, so logical quetion is: How expensive operation is it.

| Number of Operations | Duration | |---------------------: |---------------- | | 1 | ~83 μs | | 1 000 | | | 1 000 000 | ~250 ms |
