# Steiger
[](https://www.npmjs.com/package/steiger)
Universal file structure and project architecture linter.
> [!NOTE]
> The project is in beta and in active development. Some APIs may change.
> [!NOTE]
> Version 0.5.0 introduced a new config file format. We have a codemod to automatically update your config, see the [migration guide](./MIGRATION_GUIDE.md).
## Features
- Built-in set of rules to validate adherence to [Feature-Sliced Design](https://feature-sliced.design/)
- Watch mode
- Rule configurability
## Installation
```bash
npm i -D steiger
```
## Usage
```bash
npx steiger ./src
```
To run in watch mode, add `-w`/`--watch` to the command:
```bash
npx steiger ./src --watch
```
## Configuration
Steiger is zero-config! If you don't want to disable certain rules, you can safely skip this section.
Steiger is configurable via `cosmiconfig`. That means that you can create a `steiger.config.ts` or `steiger.config.js` file in the root of your project to configure the rules. Import `{ defineConfig } from "steiger"` to get autocompletion.
The config file shape is highly inspired by ESLint's config file, so if you have configured ESLint before, you'll find it easy to configure Steiger.
### Example
```javascript
// ./steiger.config.js
import { defineConfig } from 'steiger'
import fsd from '@feature-sliced/steiger-plugin'
export default defineConfig([
...fsd.configs.recommended,
{
// disable the `public-api` rule for files in the Shared layer
files: ['./src/shared/**'],
rules: {
'fsd/public-api': 'off',
},
},
])
```
> [!TIP]
> If you want Steiger to ignore certain files, add an object like this to the config array:
>
> ```js
> defineConfig([, /* … */ { ignores: ['**/__mocks__/**'] }])
> ```
Comprehensive showcase of the config file syntax
```javascript
// ./steiger.config.ts
import { defineConfig } from 'steiger'
import fsd from '@feature-sliced/steiger-plugin'
export default defineConfig([
...fsd.configs.recommended,
{
// ignore all mock files for all rules
ignores: ['**/__mocks__/**'],
},
{
files: ['./src/shared/**'],
rules: {
// disable public-api rule for files in /shared folder
'fsd/public-api': 'off',
},
},
{
files: ['./src/widgets/**'],
ignores: ['**/discount-offers/**'],
rules: {
// disable no-segmentless-slices rule for all widgets except /discount-offers
'fsd/no-segmentless-slices': 'off',
},
},
])
```
[You can see more examples here](CONFIG_EXAMPLES.md)
### Migration from 0.4.0
Version 0.5.0 introduced a new config file format. Follow the [instructions](MIGRATION_GUIDE.md) to migrate your config file.
## Rules
Currently, Steiger is not extendable with more rules, though that will change in the near future. The built-in rules check for the project's adherence to [Feature-Sliced Design](https://feature-sliced.design/).
Rule
Description
fsd/ambiguous-slice-names Forbid slice names that that match some segment’s name in the Shared layer.
fsd/excessive-slicing Forbid having too many ungrouped slices or too many slices in a group.
fsd/forbidden-imports Forbid imports from higher layers and cross-imports between slices on the same layer.
fsd/inconsistent-naming Ensure that all entities are named consistently in terms of pluralization.
fsd/insignificant-slice Detect slices that have just one reference or no references to them at all.
fsd/no-layer-public-api Forbid index files on the layer level.
fsd/no-public-api-sidestep Forbid going around the public API of a slice to import directly from an internal module in a slice.
fsd/no-reserved-folder-names Forbid subfolders in segments that have the same name as other conventional segments.
fsd/no-segmentless-slices Forbid slices that don't have any segments.
fsd/no-segments-on-sliced-layers Forbid segments (like ui, lib, api ...) that appear directly in sliced layer folders (entities, features, ...)
fsd/no-ui-in-app Forbid having the ui segment on the App layer.
fsd/public-api Require slices (and segments on sliceless layers like Shared) to have a public API definition.
fsd/repetitive-naming Ensure that all entities are named consistently in terms of pluralization.
fsd/segments-by-purpose Discourage the use of segment names that group code by its essence, and instead encourage grouping by purpose
fsd/shared-lib-grouping Forbid having too many ungrouped modules in shared/lib.
fsd/typo-in-layer-name Ensure that all layers are named without any typos.
fsd/no-processes Discourage the use of the deprecated Processes layer.
