Example

import { DynamoDBClient } from '@aws-sdk/client-dynamodb';
import { type DynmrSchema, createDynmr } from 'dynmr';

const config = {
  user: {

    name: { type: 'S', optional: true },
    age: { type: 'N' },
    sex: { type: 'S', enum: ['male', 'female'] as const },

if (user == null) {
  throw new Error('user not found');

  age: user.age + 1,
});

await client.user.del({ dynmrId });
