dynamodb-cache

A simple cache with ttl support built around DynamoDB.

Usage

import { DynamoCache } from 'dynamodb-cache';

const cache = new DynamoCache<string>({
  tableName: 'my-cache-table',
  ttlAttribute: 'ttl',
  ttlSeconds: 180
});

Creating a cache with custom serialization and deserialization functions.

const cache = new DynamoCache<string>({
  tableName: 'my-cache-table',
  ttlAttribute: 'ttl',
  ttlSeconds: 180,
  // NOTE: These are the default implementations.
  serializer: (value: string) => JSON.stringify(value),
  deserializer: (value: string) => JSON.parse(value)
});

Creating the DynamoDB table

The cache is backed by a DynamoDB table that you need to create before using the module.

The requirements are:

• A single partition key on a column named key and type string.
• An optional ttl specification on a column name of your choice, we suggest ttl (Remember to specify it when constructing a DynamoCache instance)
