TinyFrameJS

TypeScript reimplementation of MightyPork/TinyFrame.

• Original author: @cpsdqs
• Current maintainer: @MeetinaXD

Background

The original JavaScript port is no longer available, so this repository reconstructs the protocol runtime in TypeScript and adds a Vitest suite that exercises checksum variants, request/response flows, and all listener types.

During the rewrite several legacy issues were fixed:

• Frame assembly used bitwise & instead of |, corrupting peer flag propagation.
• After validating the header checksum the parser state was not reset, and it never entered the data phase correctly when payloads existed.
• Buffer length accounting included checksum bytes twice, so transmitted payloads were truncated.

Development

pnpm install
pnpm run build  # produce ESM+CJS bundles via tsdown
pnpm test       # run vitest
