Advanced tools
Package description
@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.
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);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.
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 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.

Use StringParameter.fromStringParameterAttributes.ParameterStoreSecureString has been removed. Use StringParameter.fromSecureStringParameterAttributes.ParameterOptions.name was renamed to parameterName.newStream renamed to addStream and doesn't need a scopenewSubscriptionFilter renamed to addSubscriptionFilter and doesn't need a scopenewMetricFilter renamed to addMetricFilter and doesn't need a scopeNewSubscriptionFilterProps renamed to SubscriptionPropsNewLogStreamProps renamed to LogStreamOptionsNewMetricFilterProps renamed to MetricFilterOptionsJSONPattern renamed to JsonPatternMethodOptions.authorizerId is now called authorizer and accepts an IAuthorizer which is a placeholder interface for the authorizer resource.restapi.executeApiArn renamed to arnForExecuteApi.restapi.latestDeployment and deploymentStage are now read-only.EventPattern.detail is now a map.scheduleExpression: string is now schedule: Schedule.cdk.RemovalPolicy
to configure the resource's removal policy.applyRemovalPolicy is now CfnResource.applyRemovalPolicy.RemovalPolicy.Orphan has been renamed to Retain.RemovalPolicy.Forbid has been removed, use Retain.RepositoryProps.retain is now removalPolicy, and defaults to Retain instead of remove since ECR is a stateful resourceKeyProps.retain is now removalPolicyLogGroupProps.retainLogGroup is now removalPolicyLogStreamProps.retainLogStream is now removalPolicyDatabaseClusterProps.deleteReplacePolicy is now removalPolicyDatabaseInstanceNewProps.deleteReplacePolicy is now removalPolicyattr instead of the resource type. For example, in S3 bucket.bucketArn is now bucket.attrArn.propertyOverrides has been removed from all "Cfn" resources, instead
users can now read/write resource properties directly on the resource class. For example, instead of lambda.propertyOverrides.runtime just use lambda.runtime.stageName instead of nameFunction.addLayer to addLayers and made it variadicIFunction.handler propertyIVersion.versionArn property (the value is at functionArn)SingletonLayerVersionLogRetentionPolicyStatement no longer has a fluid API, and accepts a
props object to be able to set the important fields.ImportedResourcePrincipal to UnknownPrincipal.managedPolicyArns renamed to managedPolicies, takes
return value from ManagedPolicy.fromAwsManagedPolicyName().PolicyDocument.postProcess() is now removed.PolicyDocument.addStatement() renamed to addStatements.PolicyStatement is no longer IResolvable, call .toStatementJson()
to retrieve the IAM policy statement JSON.AwsPrincipal has been removed, use ArnPrincipal instead.s3.StorageClass is now an enum-like class instead of a regular
enum. This means that you need to call .value in order to obtain it's value.s3.Coordinates renamed to s3.LocationArtifact.s3Coordinates renamed to Artifact.s3Location.BuildSpec object.lambda.Runtime.NodeJS* are now lambda.Runtime.Nodejs*Stack APIstack.name renamed to stack.stackNamestack.stackName will return the concrete stack name. Use Aws.stackName to indicate { Ref: "AWS::StackName" }.stack.account and stack.region will return the concrete account/region only if they are explicitly specified when the stack is defined (under the env prop). Otherwise, they will return a token that resolves to the AWS::AccountId and AWS::Region intrinsic references. Use Context.getDefaultAccount() and Context.getDefaultRegion() to obtain the defaults passed through the toolkit in case those are needed. Use Token.isUnresolved(v) to check if you have a concrete or intrinsic.stack.logicalId has been removed. Use stack.getLogicalId()stack.env has been removed, use stack.account, stack.region and stack.environment insteadstack.accountId renamed to stack.account (to allow treating account more abstractly)AvailabilityZoneProvider can now be accessed through Context.getAvailabilityZones()SSMParameterProvider can now be accessed through Context.getSsmParameter()parseArn is now Arn.parsearnFromComponents is now arn.formatnode.lock and node.unlock are now privatestack.requireRegion and requireAccountId have been removed. Use Token.unresolved(stack.region) insteadstack.parentApp have been removed. Use App.isApp(stack.node.root) instead.stack.missingContext is now privatestack.renameLogical have been renamed to stack.renameLogicalIdIAddressingScheme, HashedAddressingScheme and LogicalIDs are now internal. Override Stack.allocateLogicalId to customize how logical IDs are allocated to resources.--rename, and the stack
