Overview

This project tries to rebuild PgnViewerJS in Typescript. I try to get rid of some of the stuff I don't like any more, by using a better language, a better structure at the beginning, ... 😄

Overall plan

• Ensure that the base functionality of reading and writing PGN games is working again. Try to have unit tests for all aspects of the specification, and make that explicit.
• Have a stable, reliable build running all the time correct.
• Implement all functionality by Typescript classes.
• Only start working on the UI when the inner working is finished.

Specification

• See PGN Specification and Implementation Guide, especially the chapters
