Decoder Caching

• json and jwt decoders are now caching. Extracting multiple parameters from the same json/jwt property will only decode from json/jwt once.
• bug fix on Mandatory checks. Empty values are also checked.

Fixed calling mandatory validation statically

• Mandatory validators can be used statically

Min and Max Length validators

• Added MinLength and MaxLength validators
• Added ability to pass custom error messages to validators

Extract decorators can group errors

• extract_from_event and extract_from_context can now group errors

Grouping Validation Errors

• Added group_errors flag to both extract and validate decorators. By setting this flag to True, all errors for all parameters will be grouped together and returned as a list of key/value objects, where the key is the name of the validated property, and the value is a list of all the errors found when validating that parameter.
• Regular Expression validators do a full match now instead of a search.

New validators

• Added Maximum Value validator
• Added Minimum Value validator

Moved examples to its own repo

Examples have been moved to https://github.com/gridsmartercities/aws-lambda-decorators-examples, so new test.pypi releases can be tested against that repo easily.

Schema Validator

• Added schema validator. Check out SchemaValidator here

CORS

Added cors decorator, which can add cors headers to the response of the decorated function (lambda)

Handle All Exceptions Decorator

• Added the handle_all_exceptions decorator that is able to catch any type of exception and return a 400 message back.
• Made the Exception friendly message optional in the handle_exceptions decorator.
