# eslint-plugin-strict-dependencies
ESLint plugin to define custom module dependency rules.
NOTE: `eslint-plugin-strict-dependencies` uses tsconfig, tsconfig.json must be present.
## Installation
```
npm install eslint-plugin-strict-dependencies --save-dev
```
## Supported Rules
- strict-dependencies
- module: `string` (Glob or Forward matching string)
- Target module path
- targetMembers: `string[]`
- Target member name
- e.x. `["Suspense"]` in `import { Suspense } from 'react'`
- allowReferenceFrom: `string[]` (Glob or Forward matching string)
- Paths of files where target module imports are allowed.
- allowSameModule: `boolean`
- Whether it can be imported by other files in the same directory
- excludeTypeImportChecks: `boolean`
- Whether to exclude type import checks
- e.x. `import type { Suspense } from 'react'`
### Options
- resolveRelativeImport: `boolean[default = false]`
- Whether to resolve relative import as in the following example
- `src/components/aaa.ts`
```typescript
import bbb from './bbb';
```
- `resolveRelativeImport = false`: Resolve as `./bbb` (excluded from lint target)
- `resolveRelativeImport = true`: Resolve as `src/components/bbb`: (included from lint target)
- pathIndexMap: `object[default = null]`
- In eslint-plugin-strict-dependencies, path alias resolution is performed based on the paths specified in the tsconfig.
- By default, the value with an index number of `0` is used, but you can specify an option to use a value with any index number.
- Specify it as in the following example:
- `tsconfig.json`
```json
{
"compilerOptions": {
"*": ["aaa/*", "bbb/*"]
},
}
```
- `pathIndexMap = { "*": 1 } `: `"bbb/*"` is used.
## Usage
.eslintrc:
```js
"plugins": [
"strict-dependencies",
],
"rules": {
"strict-dependencies/strict-dependencies": [
"error",
[
/**
* Example:
* Limit the dependencies in the following directions
* pages -> components/page -> components/ui
*/
{
"module": "src/components/page",
"allowReferenceFrom": ["src/pages"],
// components/page can't import other components/page
"allowSameModule": false
},
{
"module": "src/components/ui",
"allowReferenceFrom": ["src/components/page"],
// components/ui can import other components/ui
"allowSameModule": true,
// components/ui exclude type import checks
"excludeTypeImportChecks": true
},
/**
* example:
* Disallow to import `next/router` directly. it should always be imported using `libs/router.ts`.
*/
{
"module": "next/router",
"allowReferenceFrom": ["src/libs/router.ts"],
"allowSameModule": false
},
/**
* example:
* Disallow to import Suspense from react. it should always be imported using `libs/react.ts`.
*/
{
"module": "react",
"targetMembers": ["Suspense"],
"allowReferenceFrom": ["src/libs/react.ts"],
"allowSameModule": false
},
],
// options
// {
// "resolveRelativeImport": true
// "pathIndexMap": { "*": 1 }
// }
]
}
