lambda_router: Python Helpers for AWS Lambdas
lambda_router is a Python package that provides a few helpers for writing Python-based AWS Lambda functions.
Its main goal is to reduce the boilerplate code when writing lambda functions that need to handle multiple routes.
Getting Started
Install with:
$ pip install lambda_routerCreating a basic, single-route app:
import lambda_router
config = lambda_router.Config()
# Load all environment variables prefix with JSR_.
config.load_from_environment(prefix="JSR_")
app = lambda_router.App(name="example_lambda", config=config)
app.route()
def main(event):
# This is the main route of your lambda
return {"message": "success"}Or a multi-route app that uses the type field in the lambda event for routing:
import lambda_router
config = lambda_router.Config()
# Load all environment variables prefix with JSR_.
config.load_from_environment(prefix="JSR_")
app = lambda_router.App(name="example_lambda", config=config, route=lambda_router.routers.EventField(key="type"))
app.route("route_one")
def main(event):
return {"message": "success from route_one"}
app.route("route_two")
def main(event):
return {"message": "success from route_two"}Contributing
