@conarti/eslint-plugin-feature-sliced

Feature-sliced design methodology plugin.

Attention: the plugin is being actively developed and is in beta. The names of rules and configurations may change in new versions. If you find a bug, please open an issue or pull request. Feel free to contribute

Features

• Works with any framework

• Support for any aliases out of the box

import { AppButton } from "~/shared/ui/app-button";
import { AppButton } from "@/shared/ui/app-button";
import { AppButton } from "@shared/ui/app-button";
import { AppButton } from "$shared/ui/app-button";
import { AppButton } from "$@#$%%shared/ui/app-button";

• Checks for absolute and relative paths

// file: src/widgets/TheHeader/ui/TheHeader.stories.tsx

import { TheHeader } from './TheHeader'; // valid
import { TheHeader } from 'src/widgets/TheHeader'; // error: should relative
import { TheHeader } from 'widgets/TheHeader'; // error: should relative
import { useBar } from '../../../shared/hooks'; // error: should absolute

• Checks for imports from public api and fix them

// file: src/features/search-articles/...

import { addCommentFormActions, addCommentFormReducer } from 'entities/Article/model/file.ts'; // error
// fix: import { addCommentFormActions, addCommentFormReducer } from 'entities/Article';

• Sort imports

import axios from "axios";                           // 1) external libs
import { Header } from "widgets/header";             // 2.1) Layers: widgets
import { Zero } from "widgets/zero";                 // 2.1) Layers: widget 
import { LoginForm } from "features/login-form";     // 2.2) Layers: features
import { globalEntities } from "entities";           // 2.4) Layers: entities
import { authModel } from "entities/auth";           // 2.4) Layers: entities
import { Cart } from "entities/cart";                // 2.4) Layers: entities 
import { One } from "entities/one";                  // 2.4) Layers: entities 
import { Two } from "entities/two";                  // 2.4) Layers: entities
import { debounce } from "shared/lib/fp";            // 2.5) Layers: shared
import { Button } from "shared/ui";                  // 2.5) Layers: shared
import { Input } from "shared/ui";                   // 2.5) Layers: shared
import { data } from "../fixtures";                  // 3) parent
import { getSmth } from "./lib";                     // 4) sibling

Installation

You'll first need to install ESLint:

npm i eslint --save-dev

Next, install @conarti/eslint-plugin-feature-sliced and dependencies:

npm install -D @conarti/eslint-plugin-feature-sliced eslint-plugin-import
# or by yarn
yarn add -D @conarti/eslint-plugin-feature-sliced eslint-plugin-import

Note: 'eslint-plugin-import' is optional. You can skip installing this plugin if you don't need to sort imports in your code.

Quick Usage

Add @conarti/feature-sliced/recommended to extends section of your .eslintrc configuration file. It enables all rules and additional recommended configs of other eslint plugins, like eslint-plugin-import.

{
  "extends": [
    "plugin:@conarti/feature-sliced/recommended"
  ]
}

Customisation

If you want to use only plugin rules, add @conarti/feature-sliced/rules instead.

{
  "extends": [
    "plugin:@conarti/feature-sliced/rules"
  ]
}

If you only want to use certain rules, you can add them individually. To do this, you need to add @conarti/feature-sliced to the 'plugins' section of the configuration file and add the desired rules to the 'rules' section. Also now you don't need to use the 'extends' section like before

{
  "plugins": [
    "@conarti/feature-sliced"
  ],
  "rules": {
    "@conarti/feature-sliced/layers-slices": "error",
    "@conarti/feature-sliced/absolute-relative": "error",
    "@conarti/feature-sliced/public-api": "error"
  }
}
