This VS Code extension was developed during a hackathon at the 2016 MVP Global Summit. This extension allows you to auto-generate UML diagrams for TypeScript applications:
Please do not expect this to be a production-ready extension: IT IS JUST AN EXPERIMENT.
I decided to share the repo because it could be used as a reference in the development of VS Code extensions.
You can use this repo to find out the following:
- How to use the TypeScript language service to access the AST generated by the TypeScript compiler.
- How to traverse the AST.
- How to access user-geerated source code from a VS Code extension.
- How to create custom VS Code commands.
- How to render a new page after triggering custom VS Code commands.
This repo is divided in two main components.
The core folder exposes a function named getDiagram.
This function expects an array of paths to be passed as an argument. The paths should point to some TypeScript source files.
The getDiagram function uses other core components:
- Parser: Traversed the TypeScript AST to create a
EntityDetailsdata structure. - Serializer: Transfroms
EntityDetailsdata structure into the UML DSL. - Renderer: Transforms the DSL into a SVG class diagram.
The function returns a Promise<string>. If the promise
is fulfilled, the returned string value will contain a svg diagram.
Contains the actial VS Code extension. It declares a new custom command. When the command is executed the current source file is passed to the code to get a class diagram. The diagram is then displayed in a new panel.

- Display inheritance relationships
- Display composition relationships
- Display "implements"
