LambdaUtilStack

Stack props can be found in LambdaProps

Example configuration

This stack provides an L3 equivalent construct that creates a Lambda with:

1. Versioning and Aliasing, each Cloudformation deployment releases a new version and updates alias
2. Extra actions that allow configuring external interactions with the lambda by providing the scope, alias, role and other
3. SQS DLQ
4. Alarms sent to SNS topic
5. Layers support via arn, zip, parameter store arn
6. VPC support
7. Role generation per environment

Example

YourStack.ts

import { App } from 'aws-cdk-lib';
import { LambdaUtilStack } from 'aws-cdk-lib-util';

const app = new App();

  artifactPath: artifactPathCvExport,
  environmentGeneration: () => ({
    APP_NAME: nameCapitalizedCvExport,
    CV_URL: `cv.${process.env.CDK_DOMAIN_NAME}`,
  }),
  extraActions: ({ lambdaAlias }) =>
    lambdaAlias.grantInvoke(
      new ServicePrincipal('cloudformation.amazonaws.com')
    ),
  isInVpc: false,
  isProvisioned: false,
  managedPolicies: ['service-role/AWSLambdaBasicExecutionRole'],

  layers: [{ paramName: PARAM_LAMBDA_CV_EXPORT_LAYER_ARN }],
