DynamoDB client.

Usage

import { createClient } from "https://denopkg.com/chiefbiiko/dynamodb/mod.ts";

// if config/credentials not passed they will be read from the env/fs
const dyno = createClient();

// the client has all of DynamoDB's operations as camelCased async methods
const result = await dyno.listTables();

The client config can be omitted entirely when calling createClient. If that is the case the config will be derived from the environment and filesystem, in that order.

Prefer using temporary credentials and a session token.
