@aval-adr/eslint-config

ESLint flat config for the decided code rules (ADR-0044) that a linter matches exactly. Versioned with the adr-lint crate.

import { adrLint, adrLintTyped } from "@aval-adr/eslint-config";

export default [
  ...adrLint({
    restrictedImports: [
      { files: ["src/domain/**"], paths: ["fs"], patterns: [{ group: ["@mui/*"] }] },
    ],
  }),
];

• adrLint({ restrictedImports = [] }) returns the config array. Each entry is { files?, paths?, patterns? }; entries with the same files (absent = all files) are concatenated into ONE @typescript-eslint/no-restricted-imports option, because flat config keeps only the last options of a rule. No entries, no such object.
• adrLintTyped(options) is adrLint(options) plus the typed rule switch-exhaustiveness-check and parserOptions.projectService: true; it needs a tsconfig.json. adrLint alone sets no typed rule and no parserOptions.

Rules and the decided rule each enforces

Narrowed, and why

• errors.never-swallowed: ESLint's no-empty flags every empty block, and also catch {} // why, which the rule body allows. adr-lint/no-swallowed-catch reports only a catch with no statement and no comment anywhere in the clause (catch (e) /* why */ {} included) or on its closing-brace line.
• general.no-disabled-safety: require-description asks a reason only of the directives that suppress; eslint-enable, global(s), exported and eslint-env suppress nothing and need none.

switch-exhaustiveness-check keeps its stock options, which are the rule body: a missing case is reported even behind a silent default, and a full switch whose default assigns to never passes.

Deferred

• components.acyclic-dependencies: import/no-cycle is deferred. It needs eslint-plugin-import-x and a TS resolver in every consumer, and its lint time is unmeasured.

Dependencies

• @eslint-community/eslint-plugin-eslint-comments: the maintained home of the disable-directive rules; owning them would mean parsing directive comments ourselves. It has no build script and no runtime dependencies beyond escape-string-regexp and ignore; if abandoned, the three rules move into adr-lint/ here.
• eslint and typescript-eslint are peer dependencies the consumer already has.
