Installation

Getting Started

This module helps you to handle different HTTP methods in your AWS Lambda.

from lambdarest import lambda_handler

@lambda_handler.handle("get")
def my_own_get(event):
    return {"this": "will be json dumped"}

##### TEST #####

input_event = {
    "body": '{}',
    "httpMethod": "GET",
    "resource": "/"
}
result = lambda_handler(event=input_event)
assert result == {"body": '{"this": "will be json dumped"}', "statusCode": 200, "headers":{}}

Anormal unittest behaviour with lambda_handler singleton

Because of python unittests leaky test-cases it seems like you shall beware of this issue when using the singleton lambda_handler in a multiple test-case scenario.

Tests

This package uses Poetry to install requirements and run tests.

Use the following commands to install requirements and run test-suite:

$ poetry install
$ poetry run task test
