Package description

What is @aws-cdk/cx-api?

@aws-cdk/cx-api is a part of the AWS Cloud Development Kit (CDK) that provides a set of APIs for interacting with the Cloud Assembly, which is the output of the CDK synthesis process. It allows developers to programmatically access and manipulate the synthesized cloud infrastructure stacks, assets, and metadata.

What are @aws-cdk/cx-api's main functionalities?

Accessing Cloud Assembly

This feature allows you to load and interact with a Cloud Assembly, which is the output directory of a CDK app synthesis. The code sample demonstrates how to load a Cloud Assembly from a specified path and log the stacks it contains.

const cxapi = require('@aws-cdk/cx-api');
const assembly = new cxapi.CloudAssembly('/path/to/cloud-assembly');
console.log(assembly.stacks);

Reading Stack Metadata

This feature allows you to read metadata from a specific stack within the Cloud Assembly. The code sample shows how to get a stack by its name and log its metadata.

const cxapi = require('@aws-cdk/cx-api');
const assembly = new cxapi.CloudAssembly('/path/to/cloud-assembly');
const stack = assembly.getStackByName('MyStack');
console.log(stack.metadata);

Listing Assets

This feature allows you to list all the assets included in the Cloud Assembly. The code sample demonstrates how to log all the assets in the Cloud Assembly.

const cxapi = require('@aws-cdk/cx-api');
const assembly = new cxapi.CloudAssembly('/path/to/cloud-assembly');
console.log(assembly.assets);

Other packages similar to @aws-cdk/cx-api

    aws-sdk

    The AWS SDK for JavaScript provides a comprehensive set of APIs for interacting with AWS services. While it does not specifically focus on the Cloud Assembly or CDK synthesis output, it allows for a wide range of AWS service interactions, including managing infrastructure, which can complement the use of @aws-cdk/cx-api.

    serverless

    The Serverless Framework is a popular open-source framework for building and deploying serverless applications. It provides functionalities for defining and deploying cloud infrastructure, similar to the CDK, but focuses on serverless architectures. It does not provide direct access to a Cloud Assembly like @aws-cdk/cx-api.

    terraform

    Terraform by HashiCorp is an open-source infrastructure as code software tool that provides a consistent CLI workflow to manage hundreds of cloud services. It allows for the definition, preview, and deployment of cloud infrastructure. While it serves a similar purpose to the CDK, it does not have a direct equivalent to the Cloud Assembly or @aws-cdk/cx-api.

Changelog

Source

0.10.0 (2018-09-27)

This release introduces a better way to "escape" L2 constructs in case of missing features by adding the ability to add arbitrary overrides for resource properties:

const bucket = new s3.Bucket(this, 'L2Bucket');

// access L1
const bucketResource = bucket.findChild('Resource') as s3.cloudformation.BucketResource;

// strongly-typed overrides
bucketResource.propertyOverrides.bucketName = 'NewBucketName';

// weakly-typed overrides
bucketResource.addPropertyOverride('BucketName', 'NewerBucketName');

Bug Fixes

  • aws-codecommit: typo in README (#780) (0e79c2d)
  • aws-ec2: fix capitalization of "VPCEndpointType" to "VpcEndpointType" (#789) (7a8ee2c), closes #765
  • docs: fix issue #718 (Aurora DB example) (#783) (016f3a8)

Code Refactoring

Features

  • aws-cloudformation: rename the CodePipeline actions (#771) (007e7b4)
  • aws-cloudformation: update the README of the module to reflect the new action names (#775) (6c0e75b), closes #771
  • aws-codedeploy: add auto-scaling groups property to ServerDeploymentGroup (#739) (0b28886)
  • aws-codedeploy: add deployment configuration construct (#653) (e6b67ad)
  • aws-codepipeline, aws-codecommit, aws-s3: change the convention for naming the source Actions to XxxSourceAction (#753) (9c3ce7f)
  • aws-elasticloadbalancingv2: support for ALB/NLB (#750) (bd9ee01)
  • tagging support for AutoScaling/SecurityGroup (#766) (3d48eb2)
  • core: resource overrides (escape hatch) (#784) (5054eef), closes #606
  • toolkit: stop creating 'empty' stacks (#779) (1dddd8a)

BREAKING CHANGES TO EXPERIMENTAL FEATURES

  • cdk: the constructor signature of TagManager has changed. initialTags is now passed inside a props object.
  • util: @aws-cdk/util is no longer available
  • aws-elasticloadbalancingv2: adds classes for modeling Application and Network Load Balancers. AutoScalingGroups now implement the interface that makes constructs a load balancing target. The breaking change is that Security Group rule identifiers have been changed in order to make adding rules more reliable. No code changes are necessary but existing deployments may experience unexpected changes.
  • aws-cloudformation: this renames all CloudFormation Actions for CodePipeline to bring them in line with Actions defined in other service packages.
  • aws-codepipeline, aws-codecommit, aws-s3: change the names of the source Actions from XxxSource to XxxSourceAction. This is to align them with the other Actions, like Build. Also, CodeBuild has the concept of Sources, so it makes sense to strongly differentiate between the two.
