TypeScript compiler visualizer

Create an interactive tool that visually traces TypeScript code through the compilation pipeline.

Why now

As TypeScript grows, developers need better educational tools to understand its increasingly complex type system.

Who for
TypeScript developers
Business model
Pro features and corporate licenses
Effort
A few months

Developers often struggle to debug TypeScript errors because the compilation process is opaque.

Build a web app that shows code transforming step-by-step through parsing, type checking and emit with explanations.

Monetize through corporate training packages and IDE plugin integrations.

The MVP could visualize just basic type inference before handling advanced features.

Challenge is making complex compiler concepts accessible without oversimplifying.
