A toolkit for serverless and AWS, with a focus on AWS Lambda and dynamodb.

Py aws Lambda Toolkit

This is a lightweight Python toolkit for easily and quickly creating AWS Lambda functions with the Serverless Framework. It includes the following features:

• DynamoDB shortcuts: Avoid boilerplate code for DynamoDB operations.
• HTTP event processing: Get the event of the HTTP request and parse it, splitting it into the path, query string, body, headers, etc.
• HTTP response shortcuts: Create HTTP responses with the correct format and status code.
• JWT authentication: Create and verify JWT tokens as easily as possible.
• Logger: Log messages with a format that is easy to read.
• Mappers: Remove specified fields from a dictionary or list of dictionaries.
• Parser: Convert dictionary keys to snake case or camel case.
• Password hashing: Hash passwords with salt and verify them.
• DynamoDB scan builder: Build a scan query with specified filters.
• Validator: Validate a dictionary with specified rules.
