v8.0.0 incompatible with TypeScript 7 (with workaround)

Author: johnhunterCreated Aug 26, 2026Updated Sep 9, 2026

Madge 8.0.0 declares TypeScript ^5.4.4, while current TypeScript is 7.x.x; its dependency tree resolves @typescript-eslint/typescript-estree, which accesses the removed/changed ts.Extension.Cjs surface during startup.

The following error is output:

madge --circular --extensions ts,tsx src

<project-path>/node_modules/@typescript-eslint/typescript-estree/dist/create-program/shared.js:59
    ts.Extension.Cjs,
