mango-repo v4.0.1

jok-mango

Simplified way 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 'jok-mango'

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

2. Create repository object for declared type

import { getRepository } from 'jok-mango'

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: 'test@jok.io',
	passwordHash: 'strong-hash',
})

const { id, version } = user

const updatedUser = await users.update(
	{ id, version },
	{
		email: 'tester@jok.io',
	},
)

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.
