spine-core-aws-common

Common code used across Spine projects in AWS

Installation

Simply add the pre-built package to your python environment.

The latest version can be obtained with the following curl command if your system has it present:

package_version=$(curl -SL https://github.com/NHSDigital/spine-core-aws-common/releases/latest | grep -Po 'Release v\K(\d+.\d+.\d+)' | head -n1)

Or you can set a specific version:

package_version="0.2.3"

Alternatively the main page of this repo will display the latest version i.e. 0.2.3, and previous versions can be searched, which you can substitute in place of ${package_version} in the below commands.

Quick example

from spine_aws_common import LambdaApplication

class MyApp(LambdaApplication):
    def initialise(self):
        # initialise
        return

    def start(self):
        # do actual work
        # to set response for the lambda
        self.response = '{"my new response":true}'
        return

# create instance of class in global space
# this ensures initial setup of logging/config is only done on cold start
app = MyApp(additional_log_config='/path/to/mylogconfig.cfg')

def lambda_handler(event, context):
    return app.main(event, context)

API Gateway example

from spine_aws_common import APIGatewayApplication
from aws_lambda_powertools.event_handler.api_gateway import Response

class MyApp(APIGatewayApplication):
    def get_hello(self):
        return Response(
            status_code=200, content_type="application/json", body='{"hello":"world"}'
        )

    def get_id(self, _id):
        response_dict = {"id": _id}
        return Response(
            status_code=200,
            content_type="application/json",
            body=json.dumps(response_dict),
        )

    def configure_routes(self):
        self._add_route(self.get_hello, "/hello")
        self._add_route(self.get_id, "/id/<_id>")

# create instance of class in global space
# this ensures initial setup of logging/config is only done on cold start
app = MyApp(additional_log_config='/path/to/mylogconfig.cfg')

def lambda_handler(event, context):
    return app.main(event, context)
