DynoSOR

DynamoDB Structured Object Relations

This is currently a POC for a better Typescript DynamoDB ORM-like service.

Goals:

Out of the box runtime validation with zod.
Opinonated DynamoDB interface pattern.

Getting started

Install the POC

npm i -S git+https://github.com/yashvesikar/dyno-orm.git

Usage

Basic Usage

Simplest way to use is to pass the entity definition and DynamoDB client configurations directly into the createService function.

import { createService } from "dyno-orm";

const { entity: User, service: UserService } = createService(
    z.object({
        ... your attributes
    }),
    {
        client: {
            region: "us-east-1",
            ... your dynamodb client configurations
        }
    }
)

Extending BaseService

To customize and extend the BaseService the createService function takes an optional service parameter.

import { BaseService, createService } from "dyno-orm";

const entity = z.object({
        ... your attributes
    });

class CustomService extends BaseService<typeof entity>{
    async customGet() {
        // has access to BaseService attributes like this.table
        // can use super.get()
    }
}

// UserService will be an instance of CustomService
const { entity: User, service: UserService } = createService(
    entity,
    {
        client: {
            region: "us-east-1",
            ... your dynamodb client configurations
        }
    },
    CustomService
)
