Scynamo - Library to convert between DynamoDB and Scala types

Scynamo is a library to map your Scala case classes/sealed traits to and from DynamoDB. For that the library uses the typeclass approach and is very similar to other libraries in the Scala ecosystem.

Overview of Features

• derive instances for your ADTs to encode/decode from/to DynamoDB
• precise error messages for nested case classes/lists/maps/...
• customize the derivation of case classes and sealed traits using options
• AttributeValue-Syntax for null-safe accessors
• provides optional syntax for encoding/decoding (see scynamo.syntax.*)
• safe: Instead of silently encoding empty {String,Number,Binary} Sets, this operation fails in scynamo, allowing you to catch the error before even reaching DynamoDB. See https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Limits.html.
