serverless-dynamo-client

AWS DynamoDB client

This is a wrapper around the official AWS.DynamoDB SDK that:

• Plays nicely with serverless-offline by providing sane default behavior based on IS_OFFLINE environment variable.
• Looks for the AWS region config in configurable environment variable

API

Shared [options]

The following options are shared between the two methods below.

• envPrefix {string} if this is set, DDB will look for config in environment variables prefixed by envPrefix.
• region {string} if not set, DDB will look in ${envPrefix}_REGION. If envPrefix is not set, it looks at AWS_REGION. If still not found, when in serverless-offline mode, it will fall back to localhost
• endpoint {string} if in serverless-offline mode, this defaults to http://localhost:8000
• sslEnabled {boolean} defaults to true, if in serverless-offline mode, it is set to false
