Detection

The TypeScript adapter is favored when a tsconfig.json exists at the project root and .ts / .tsx files are present (file-count heuristic vs other adapters).

​
Analysis

The TypeScript adapter’s static analysis integration is still evolving. In current builds, deep issue finding may be limited compared to Python; the pipeline still supports blast radius construction, transforms for supported fixers (for example whitespace), and verification (syntax, imports, tests). Use Python projects for the full seven-analyzer experience until TS analysis catches up.

​
Auto-fixes

Fixers that only need text transforms (for example trailing whitespace) work on .ts / .tsx files. More complex semantic fixes follow the same verification gate as Python.

​
Verification

  • Syntax — TypeScript compiler API in check-only mode.
  • Imports — Module resolution against the project layout.
  • Tests — vitest or jest auto-detection where implemented.

​
Requirements

  • Node.js 18+
  • tsconfig.json for typical project detection
