Cdk-dia diagrams your CDK provisioned infrastructure using the Graphviz dot language.

This Diagram was automatically generated from an AWS CDK stack

Add cdk-dia to your CDK project

npm install cdk-dia

Install Graphviz

brew install graphviz

• If you don't use brew: Graphviz installation in many environments is well documented.
• make sure Graphviz's dot binary is available in your PATH.

Synthesize your CDK application

cdk synth

Generate a CDK-DIA diagram PNG

npx cdk-dia

Generate a CDK-DIA diagram as an interactive HTML (experimental)

npx cdk-dia --rendering cytoscape-html

Globally install cdk-dia

npm install cdk-dia -g

Install Graphviz

brew install graphviz

• If you don't use brew: Graphviz installation in many environments is well documented.
• make sure Graphviz's dot binary is available in your PATH.

Generate a CDK-DIA diagram

cdk-dia

In some cases it is useful to be able to tweak a diagram. For this purpose CDK-DIA includes customizers/decorators you can use with your CDK constructs in order to tweak the diagram.

• Customization and decorators are currently only support for Typescript/Javascript CDK projects.
• In order to customize you have to add cdk-dia as a npm project dependency (globally installing it using npm i -g won't allow you to use the CdkDiaDecorator class)

Consider the following diagram of a 3-Tier CDK Stack:

In this diagram CDK-DIA collapsed the DBTier (done automatically to any CDK Level 2 (L2) construct) in order to create a diagram which contains the most important details.

One can use a decorator in order to customize the diagram and prevent CDK-DIA from collapsing the Construct.

This is done by implementing CDK's IInpectable's interface and using CDK-DIA's decorator. example:

This results in a Diagram where the DB-Tier was not collapsed providing more details:

• a full example or the above can be found at examples/decoration-example

• npx cdk-dia --help - Get possible arguments
• npx cdk-dia --stacks stackOne stackFour - only diagram chosen aws-cdk stacks
  • npx cdk-dia --stacks pipelinestack/prod/database - choose stacks by path (nested stacks, pipeline stacks)
