Add to your ESLint config:

import fta from "eslint-plugin-fta";
import typescriptParser from "@typescript-eslint/parser";

export default [
  {
    files: ["src/**/*.ts"],
    languageOptions: {
      parser: typescriptParser,
    },
    plugins: {
      fta,
    },
    rules: {
      // Warn when complexity is between 50-60
      "fta/complexity-could-be-better": [
        "warn",
        { "when-above": 50, "when-at-or-under": 60 },
      ],

      // Error when complexity is above 60
      "fta/complexity-needs-improvement": ["error", { "when-above": 60 }],
    },
  },
];

Rules

• complexity-could-be-better: Warns when FTA score is between specified thresholds
• complexity-needs-improvement: Errors when FTA score exceeds threshold
