B.TwilioSdkLayer

An AWS CDK based lambda layer containing Twilio SDK for python.

Description

This library is intended to simplify Twilio SDK dependency management in AWS architectures where Twilio logic is being handled with lambda functions. Simply include this layer when creating a lambda function to enable Twilio functionality.

NOTE! In order to use this layer, a docker command must be available on your machine. It is because the CDK runs a bundling command on a docker container to create the Twilio dependency.

Remarks

Biomapas aims to modernise life-science industry by sharing its IT knowledge with other companies and the community. This is an open source library intended to be used by anyone. Improvements and pull requests are welcome.

from b_twilio_sdk_layer.layer import Layer as TwilioLayer
from b_cfn_lambda_layer.package_version import PackageVersion

Function(
    scope=stack,
    id='MyCoolFunction',
    function_name='MyCoolFunction',
    code=Code.from_asset('/path/to/your/code'),
    handler='index.handler',
    runtime=Runtime.PYTHON_3_8,
    layers=[TwilioLayer(
        stack,
        'MyCoolTwilioLayer',
        twilio_sdk_version=PackageVersion.from_string_version('7.4.0')
    )],
)
