ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@aws-cdk/cx-api
Advanced tools
@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.
This is a developer preview (public beta) module. Releases might lack important features and might have future breaking changes.
This API is still under active development and subject to non-backward compatible changes or removal in any future version. Use of the API is not recommended in production environments. Experimental APIs are not subject to the Semantic Versioning model.
This module is part of the AWS Cloud Development Kit project.
