# Migrate to Oxlint

Guides users through migrating a JavaScript/TypeScript project from ESLint to Oxlint using the @oxlint/migrate tool. Covers automated migration, config review, and handling unsupported features.

**Install:** `git clone https://github.com/Ohh-889/skyroc-admin`

## README

This skill guides you through migrating a JavaScript/TypeScript project from ESLint to [Oxlint](https://oxc.rs/docs/guide/usage/linter/).

## Overview

Oxlint is a high-performance linter that implements many popular ESLint rules natively in Rust. It can be used alongside ESLint or as a full replacement.

An official migration tool is available, and will be used by this skill: [`@oxlint/migrate`](https://github.com/oxc-project/oxlint-migrate)

## Step 1: Run Automated Migration

Run the migration tool in the project root:

```bash
npx @oxlint/migrate
```

This reads your ESLint flat config (`eslint.config.js` for example) and generates a `.oxlintrc.json` file from it. It will find your ESLint config file automatically in most cases.

See options below for more info.

### Key Options

| Option                      | Description                                                                                                                     |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
| `--type-aware`              | Include type-aware rules from `@typescript-eslint` (will require the `oxlint-tsgolint` package to be installed after migrating) |
| `--with-nursery`            | Include experimental rules still under development, may not be fully stable or consistent with ESLint equivalents               |
| `--js-plugins [bool]`       | Enable/disable ESLint plugin migration via `jsPlugins` (default: enabled)                                                       |
| `--details`                 | List rules that could not be migrated                                                                                           |
| `--replace-eslint-comments` | Convert all `// eslint-disable` comments to `// oxlint-disable`                                                                 |
| `--output-file <file>`      | Specify a different output path (default: `.oxlintrc.json`)                                                                     |

If your ESLint config is not at the default location, pass the path explicitly:

```bash
npx @oxlint/migrate ./path/to/eslint.config.js
```

## Step 2: Review Generated Config

After migration, review the generated `.oxlintrc.json`.

### Plugin Mapping

The migration tool automatically maps ESLint plugins to oxlint's built-in equivalents. The following table is for reference when reviewing the generated config:

| ESLint Plugin                                       | Oxlint Plugin Name |
| --------------------------------------------------- | ------------------ |
| `@typescript-eslint/eslint-plugin`                  | `typescript`       |
| `eslint-plugin-react` / `eslint-plugin-react-hooks` | `react`            |
| `eslint-plugin-import` / `eslint-plugin-import-x`   | `import`           |
| `eslint-plugin-unicorn`                             | `unicorn`          |
| `eslint-plugin-jsx-a11y`                            | `jsx-a11y`         |
| `eslint-plugin-react-perf`                          | `react-perf`       |
| `eslint-plugin-promise`                             | `promise`          |
| `eslint-plugin-jest`                                | `jest`             |
| `@vitest/eslint-plugin`                             | `vitest`           |
| `eslint-plugin-jsdoc`                               | `jsdoc`            |
| `eslint-plugin-next`                                | `nextjs`           |
| `eslint-plugin-node`                                | `node`             |
| `eslint-plugin-vue`                                 | `vue`              |

Default plugins (enabled when `plugins` field is omitted): `unicorn`, `typescript`, `oxc`.
Setting the `plugins` array explicitly overrides these defaults.

ESLint core rules are usable in oxlint without needing to configure a plugin in the config file.

### Rule Categories

Oxlint groups rules into categories for bulk configuration, though only `correctness` is enabled by default:

```json
{
  "categories": {
    "correctness": "error",
    "suspicious": "warn"
  }
}
```

Available categories: `correctness` (default: enabled), `suspicious`, `pedantic`, `perf`, `style`, `restriction`, `nursery`.

Individual rule settings in `rules` override category settings.

`@oxlint/migrate` will turn `correctness` off to avoid enabling additional rules that weren't enabled by your ESLint config. You can choose to enable additional categories after migration if desired.

### Check Unmigrated Rules

Run with `--details` to see which ESLint rules could not be migrated:

```bash
npx @oxlint/migrate --details
```

Review the output and decide whether to keep ESLint for those rules or not. Some rules may be mentioned in the output from `--details` as having equivalents in oxlint that were not automatically mapped by the migration tool. In those cases, consider enabling the equivalent oxlint rule manually after migration.

## Step 3: Install Oxlint

Install the core oxlint package (use `yarn install`, `pnpm install`, `vp install`, `bun install`, etc. depending on your package manager):

```bash
npm install -D oxlint
```

If you want to add the `oxlint-tsgolint` package, if you intend to use type-aware rules that require TypeScript type information:

```bash
npm install -D oxlint-tsgolint
```

No other packages besides the above are needed by default, though you will need to keep/install any additional ESLint plugins that were migrated into `jsPlugins`. Do not add `@oxlint/migrate` to the package.json, it is meant for one-off usage.

## Step 4: Handle Unsupported Features

Some features require manual attention:

- Local plugins (relative path imports): Must be migrated manually to `jsPlugins`
- `eslint-plugin-prettier`: Supported, but very slow. It is recommended to use [oxfmt](https://oxc.rs/docs/guide/usage/formatter) instead, or switch to `prettier --check` as a separate step alongside oxlint.
- `settings` in override configs: Oxlint does not support `settings` inside `overrides` blocks.
- ESLint v9+ plugins: Not all work with oxlint's JS Plugins API, but the majority will.

### Local Plugins

If you have any custom ESLint rules in the project repo itself, you can migrate them manually after running the migration tool by adding them to the `jsPlugins` field in `.oxlintrc.json`:

```json
{
  "jsPlugins": ["./path/to/my-plugin.js"],
  "rules": {
    "local-plugin/rule-name": "error"
  }
}
```

### External ESLint Plugins

For ESLint plugins without a built-in oxlint equivalent, use the `jsPlugins` field to load them:

```json
{
  "jsPlugins": ["eslint-plugin-custom"],
  "rules": {
    "custom/my-rule": "warn"
  }
}
```

## Step 5: Update CI and Scripts

Replace ESLint commands with oxlint. Path arguments are optional; oxlint defaults to the current working directory.

```bash
# Before
npx eslint src/
npx eslint --fix src/

# After
npx oxlint src/
npx oxlint --fix src/
```

### Common CLI Options

| ESLint                    | oxlint equivalent                              |
| ------------------------- | ---------------------------------------------- |
| `eslint .`                | `oxlint` (default: lints the cwd)              |
| `eslint src/`             | `oxlint src/`                                  |
| `eslint --fix`            | `oxlint --fix`                                 |
| `eslint --max-warnings 0` | `oxlint --deny-warnings` or `--max-warnings 0` |
| `eslint --format json`    | `oxlint --format json`                         |

Additional oxlint options:

- `--tsconfig <path>`: Specify tsconfig.json path, likely unnecessary unless you have a non-standard name for `tsconfig.json`.

## Tips

- You can run alongside ESLint if necessary: Oxlint is designed to complement ESLint during migration, but with JS Plugins many projects can switch over fully without losing many rules.
- Disable comments work: `// eslint-disable` and `// eslint-disable-next-line` comments are supported by oxlint. Use `--replace-eslint-comments` when running @oxlint/migrate to convert them to `// oxlint-disable` equivalents if desired.
- List available rules: Run `npx oxlint --rules` to see all supported rules, or refer to the [rule documentation](https://oxc.rs/docs/guide/usage/linter/rules.html).
- Schema support: Add `"$schema": "./node_modules/oxlint/configuration_schema.json"` to `.oxlintrc.json` for editor autocompletion if the migration tool didn't do it automatically.
- Output formats: `default`, `stylish`, `json`, `github`, `gitlab`, `junit`, `checkstyle`, `unix`
- Ignore files: `.eslintignore` is supported by oxlint if you have it, but it's recommended to move any ignore patterns into the `ignorePatterns` field in `.oxlintrc.json` for consistency and simplicity. All files and paths ignored via a `.gitignore` file will be ignored by oxlint by default as well.
- If you ran the migration tool multiple times, remove the `.oxlintrc.json.bak` backup file created by the migration tool once you've finished migrating.
- If you are not using any JS Plugins and have replaced your ESLint configuration, you can remove all ESLint packages from your project dependencies.
- Ensure your editor is configured to use oxlint instead of ESLint for linting and error reporting. You may want to install the Oxc extension for your preferred editor. See https://oxc.rs/docs/guide/usage/linter/editors.html for more details.
