plantuml-parser 0.0.12 introduces TypeScript declarations. Now you can parse PlantUML and get a fully typed result. PlantUML diagrams are awesome! In this post I first give a brief introduction into PlantUML. Then I will show how you can use plantuml-parser with TypeScript to make the most out of your diagrams.
