CODEMOD ADDS TOML SUPPORT AS TYPESCRIPT NATIVE PREVIEW ADVANCES

By RepoJournal · Filed · About Node.js

The jssg-types library shipped TOML language node support overnight, expanding codemod's AST capabilities just as TypeScript's native preview build marches toward production.

Codemod released @codemod.com/jssg-types 1.6.2 [1] with native TOML language node types and a new ast-grep/langs/toml module, giving developers broader language coverage for code transformation tooling. The timing matters: TypeScript native preview ticked forward to 7.0.0-dev.20260611.2 [2], narrowing the gap to a full release and signaling the Go-based rewrite is tracking toward stability. Neither change breaks existing workflows, but the TOML addition extends codemod's reach into modern configuration file patterns that Node projects increasingly rely on. Reliability desk merged its 2026-06-17 report , while the meeting artifacts bundler fixed a naming issue [3] that was causing coordination friction across working groups.
