## Diagram Plugin - Cdk Graph
`@aws-prototyping-skd/cdk-graph-plugin-diagram`

[](https://aws.github.io/aws-prototyping-sdk/typescript/cdk-graph-plugin-diagram/index.html)
[](https://github.com/aws/aws-prototyping-sdk/tree/mainline/packages/cdk-graph-plugin-diagram)
This plugin generates diagrams utilizing the [cdk-graph](https://aws.github.io/aws-prototyping-sdk/typescript/cdk-graph/index.html) framework.
> More comprehensive documentation to come as this package stabilizes.
> **Disclaimer:** This is the first **cdk graph** plugin, it is highly *experimental*, and subject to major refactors as we gain feedback from the community.

### Quick Start
```python
// bin/app.ts
// Must wrap cdk app with async IIFE function to enable async cdk-graph report
(async () => {
const app = new App();
// ... add stacks, etc
const graph = new CdkGraph(app, {
plugins: [new CdkGraphDiagramPlugin()],
});
app.synth();
// async cdk-graph reporting hook
await graph.report();
})
// => cdk.out/diagram.dot
// => cdk.out/diagram.svg
// => cdk.out/diagram.png
```
> This plugin currently only supports `async report()` generation following the above example. **Make sure to wrap the cdk app with *async IIFE*.**

### Next Steps
* [ ] Battle test in the wild and get community feedback
* [ ] Improve image coverage and non-image node rendering
* [ ] Add drawio support
* [ ] Add common filter patterns and helpers
* [ ] Enable generating diagrams outside of synthesis process (maybe CLI)
* [ ] Implement interactive diagram, with potential for dynamic filtering and config generation
* [ ] Support using interactive diagram as config generator for other plugins (or as separate plugin that depends on this)
