Configuration

Necro runs zero-config. To customize which files it analyzes, add a necro.config.json to your project root.

necro.config.json

{
  "include": ["**/*.ts", "**/*.tsx"],
  "ignore": ["**/node_modules/**", "**/dist/**"]
}

Keys

Key	Type	Default	Description
include	string[]	["**/*.ts", "**/*.tsx"]	Globs of files to analyze.
ignore	string[]	["**/node_modules/**", "**/dist/**"]	Globs to exclude.

Each key you set replaces its default (values are merged per key, not concatenated). If you set ignore, include the defaults you still want:

necro.config.json

{
  "ignore": ["**/node_modules/**", "**/dist/**", "**/*.generated.ts"]
}

Declaration files (*.d.ts) and the directories node_modules, .git, dist, build, and coverage are always skipped.

What’s not configurable yet

Entry-point overrides, per-detector thresholds, and tier tuning are planned. Today, entry points are resolved automatically from package.json and your test-runner config.

See the full configuration reference for the authoritative key list.
