I have just released a tool called TypeDoc that generates html api documentation pages out of TypeScript *.ts files.
The documentation generator runs the TypeScript compiler and extracts the type information from the generated compiler symbols. Therefore you don’t have to include any additional metadata within your comments.
If you want to try it out, simply install and run the tool through npm:
npm install typedoc --global typedoc --out path/to/documentation/ path/to/typescript/project/
If you want to know what a documentation created with TypeDoc looks like, head over to the GitHub page of the project:
