Learnings from ts-blank-space

tags: TypeScript, type erasure, type stripping

ts-blank-space

As part of my work on the JavaScript Tooling team at Bloomberg I have implemented an experimental (not yet used in production) package to transform TypeScript into JavaScript using a somewhat novel approach.

This is a description of what I learned from implementing the idea. The source code will be open sourced soon - it just needs some regular IP approval.

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

// This is Node script that uses Puppeteer (headless Chrome) to measure the decode time
