+# @robonen/eslint
+
+Composable [ESLint](https://eslint.org) flat-config presets.
+
+## Install
+
+```bash
+pnpm install -D @robonen/eslint eslint jiti
+```
+
+> `jiti` lets ESLint load a TypeScript `eslint.config.ts`.
+
+## Usage
+
+Create `eslint.config.ts` in your project root:
+
+```ts
+import { compose, base, typescript, vue, vitest, imports } from '@robonen/eslint';
+
+export default compose(base, typescript, vue, vitest, imports);
+```
+
+Append custom config objects after presets to override them:
+
+```ts
+import { compose, base, typescript } from '@robonen/eslint';
+
+export default compose(base, typescript, {
+  rules: { 'no-console': 'off' },
+}, {
+  files: ['**/*.vue'],
+  rules: { '@stylistic/no-multiple-empty-lines': 'off' },
+});
+```
+
+## Presets
+
+| Preset       | Plugin(s)                              | Description                                    |
+| ------------ | -------------------------------------- | ---------------------------------------------- |
+| `base`       | `@eslint/js`, `eslint-plugin-unicorn`  | Core eslint + unicorn rules, global ignores    |
+| `typescript` | `typescript-eslint`                    | TypeScript rules (`**/*.ts`, `**/*.vue`)       |
+| `vue`        | `eslint-plugin-vue`                    | Vue 3 Composition API / `<script setup>` rules |
+| `vitest`     | `@vitest/eslint-plugin`                | Test file rules                                |
+| `imports`    | `eslint-plugin-import-x`               | Import rules (cycles, duplicates, ordering)    |
+| `node`       | `eslint-plugin-n`                      | Node.js-specific rules                         |
+| `stylistic`  | `@stylistic/eslint-plugin`             | Formatting rules                               |
+
+`ignores` is also exported on its own if you only want the global ignore list.
+
+## Migrating from `@robonen/oxlint`
+
+This package replaces `@robonen/oxlint`. The preset names and intent are
+preserved, with these mapping notes:
+
+- `eslint/*` rules → ESLint core rules (no prefix), e.g. `eslint/no-console` → `no-console`.
+- `typescript/*` → `@typescript-eslint/*`.
+- `import/*` → `import-x/*` (via `eslint-plugin-import-x`).
+- `node/*` → `n/*` (via `eslint-plugin-n`).
+- `@stylistic/*` and `unicorn/*` are unchanged.
+- `oxc/*` rules are oxc-exclusive and have **no ESLint equivalent**; they are
+  dropped. Their intent is largely covered by `@eslint/js` recommended and
+  `unicorn`.
+- `categories`/`env`/`ignorePatterns` (oxlint config keys) are replaced by flat
+  config equivalents: `@eslint/js` recommended, `languageOptions.globals`, and
+  the `ignores` preset.
+
+## API
+
+### `compose(...configs): FlatConfigArray`
+
+Flattens presets (arrays) and inline overrides (single objects) into one ordered
+flat config array. Later entries override earlier ones — ESLint flat-config
+semantics. Falsy entries (`false`/`null`/`undefined`) are skipped, enabling
+conditional composition.

-# @robonen/oxlint
-
-Composable [oxlint](https://oxc.rs/docs/guide/usage/linter.html) configuration presets.
-
-## Install
-
-```bash
-pnpm install -D @robonen/oxlint oxlint
-```
-
-## Usage
-
-Create `oxlint.config.ts` in your project root:
-
-```ts
-import { defineConfig } from 'oxlint';
-import { compose, base, typescript, vue, vitest, imports } from '@robonen/oxlint';
-
-export default defineConfig(
-  compose(base, typescript, vue, vitest, imports),
-);
-```
-
-Append custom rules after presets to override them:
-
-```ts
-compose(base, typescript, {
-  rules: { 'eslint/no-console': 'off' },
-  ignorePatterns: ['dist'],
-});
-```
-
-## Presets
-
-| Preset       | Description                                        |
-| ------------ | -------------------------------------------------- |
-| `base`       | Core eslint, oxc, unicorn rules                    |
-| `typescript` | TypeScript-specific rules (via overrides)           |
-| `vue`        | Vue 3 Composition API / `<script setup>` rules     |
-| `vitest`     | Test file rules (via overrides)                    |
-| `imports`    | Import rules (cycles, duplicates, ordering)        |
-| `node`       | Node.js-specific rules                             |
-
-## Rules Documentation
-
-Подробные описания правил и `good/bad` примеры вынесены в отдельную директорию:
-
-- `rules/README.md`
-- `rules/base.md`
-- `rules/typescript.md`
-- `rules/vue.md`
-- `rules/vitest.md`
-- `rules/imports.md`
-- `rules/node.md`
-- `rules/stylistic.md`
-
-## API
-
-### `compose(...configs: OxlintConfig[]): OxlintConfig`
-
-Merges multiple configs into one:
-
-- **plugins** — union (deduplicated)
-- **rules / categories** — last wins
-- **overrides / ignorePatterns** — concatenated
-- **env / globals** — shallow merge
-- **settings** — deep merge

-# node preset
-
-## Purpose
-
-Node.js-правила и окружение `env.node = true`.
-
-## Key Rules
-
-- `node/no-exports-assign`: запрещает перезапись `exports`.
-- `node/no-new-require`: запрещает `new require(...)`.
-
-## Examples
-
-```ts
-// ✅ Good
-module.exports = { run };
-const mod = require('./mod');
-
-// ❌ Bad
-exports = { run };
-const bad = new require('./mod');
-```

-# typescript preset
-
-## Purpose
-
-TypeScript-правила для `.ts/.tsx/.mts/.cts` через `overrides`.
-
-## Key Rules
-
-- `typescript/consistent-type-imports`: выносит типы в `import type`.
-- `typescript/no-import-type-side-effects`: запрещает сайд-эффекты в type import.
-- `typescript/prefer-as-const`.
-- `typescript/no-namespace`, `typescript/triple-slash-reference`.
-- `typescript/no-wrapper-object-types`: запрещает `String`, `Number`, `Boolean`.
-
-## Examples
-
-```ts
-// ✅ Good
-import type { User } from './types';
-
-const status = 'ok' as const;
-interface Payload {
-  value: string;
-}
-
-// ❌ Bad
-import { User } from './types';
-
-type Boxed = String;
-namespace Legacy {
-  export const x = 1;
-}

+## Presets
+
+| Preset | Extends | Use for |
+| --- | --- | --- |
+| `tsconfig.base.json` | — | Node / isomorphic libraries (`lib: ESNext`, no DOM) |
+| `tsconfig.dom.json` | base | Browser libraries (adds `DOM`, `DOM.Iterable`) |
+| `tsconfig.vue.json` | dom | Vue SFC libraries / apps (adds `jsx`, `vueCompilerOptions`) |
+| `tsconfig.node.json` | base | Build/test tooling files (`*.config.ts`) — adds `types: ["node"]`, no DOM |
+| `tsconfig.json` | base | Default alias for `base` (bare `@robonen/tsconfig` import) |
+
 ## Usage
 
-Extend from it in your `tsconfig.json`:
+Pick the preset that matches the package and extend it:
 
-```json
+```jsonc
+// Node / isomorphic library
+{ "extends": "@robonen/tsconfig/tsconfig.base.json" }
+```
+
+```jsonc
+// Browser library
+{ "extends": "@robonen/tsconfig/tsconfig.dom.json" }
+```
+
+```jsonc
+// Vue package, with path aliases
 {
-  "extends": "@robonen/tsconfig/tsconfig.json"
+  "extends": "@robonen/tsconfig/tsconfig.vue.json",
+  "compilerOptions": {
+    "paths": { "@/*": ["./src/*"] }
+  }
 }
 ```
 
-## What's Included
+> Path aliases resolve relative to the `tsconfig.json` location — `baseUrl` is
+> intentionally omitted (deprecated, removed in TypeScript 7.0).
 
-- **Target / Module**: ESNext with Bundler resolution
-- **Strict mode**: `strict`, `noUncheckedIndexedAccess`
-- **Module safety**: `verbatimModuleSyntax`, `isolatedModules`
-- **Declarations**: `declaration` enabled
-- **Interop**: `esModuleInterop`, `allowJs`, `resolveJsonModule`
+## Project references (DOM + Node split)
+
+Most packages contain two environments: browser/library `src` (DOM) and Node
+tooling files (`vite.config.ts`, `vitest.config.ts`, `tsdown.config.ts`). They
+are split into separate projects wired with references, so `src` never sees Node
+globals and config files never see `DOM`:
+
+```jsonc
+// tsconfig.json — solution root, tools (tsdown/vitest/editor) target src below
+{
+  "files": [],
+  "references": [
+    { "path": "./tsconfig.src.json" },
+    { "path": "./tsconfig.node.json" }
+  ]
+}
+```
+
+```jsonc
+// tsconfig.src.json — the library code
+{
+  "extends": "@robonen/tsconfig/tsconfig.dom.json",
+  "compilerOptions": {
+    "composite": true,
+    "types": [],
+    "tsBuildInfoFile": "./node_modules/.tmp/tsconfig.src.tsbuildinfo"
+  },
+  "include": ["src/**/*.ts"]
+}
+```
+
+```jsonc
+// tsconfig.node.json — build/test tooling files
+{
+  "extends": "@robonen/tsconfig/tsconfig.node.json",
+  "compilerOptions": {
+    "composite": true,
+    "tsBuildInfoFile": "./node_modules/.tmp/tsconfig.node.tsbuildinfo"
+  },
+  "include": ["*.config.ts"]
+}
+```
+
+Type-check the whole package (both projects) with `tsc -b` / `vue-tsc -b`.
+Point `tsdown` at the src project (`tsconfig: './tsconfig.src.json'`) since the
+root has no `compilerOptions`.
+
+## What's included (base)
+
+- **Target / Module**: `ESNext` with `module: Preserve` + `Bundler` resolution
+- **Strict mode**: `strict`, `noUncheckedIndexedAccess`, `noImplicitOverride`,
+  `noImplicitReturns`, `noFallthroughCasesInSwitch`, `noUncheckedSideEffectImports`
+- **Module safety**: `verbatimModuleSyntax`, `isolatedModules`, `moduleDetection: force`
+- **Type-check only**: `noEmit` (declarations/output are produced by `tsdown`)
+- **Interop**: `esModuleInterop`, `resolveJsonModule`
