eslint-docs

根據官方文件,教授當前 ESLint 10 的最佳實踐。適用於編寫、審查或修正 eslint.config.js(flat config、defineConfig、files、ignores、globalIgnores、extends、languageOptions、globals、parsers、processors)、設定 ESLint 規則和嚴重程度、禁用註解與行內設定、在 CI 中執行 CLI(--fix、--cache、--quiet、--max-warnings、大量抑制、格式化工具、功能標誌、MCP 伺服器)、編寫自訂規則(meta、schema、fixes、suggestions、selectors、scope、code paths)並使用 RuleTester 進行測試、建構外掛、可共享設定、自訂解析器、處理器或格式化工具、使用 Node.js API(ESLint、Linter),或從 eslintrc 遷移至 ESLint 9 或 10。觸發條件為 eslint、eslint.config.js、flat config、.eslintrc、.eslintignore、@eslint/js、js/recommended、eslint-disable、no-unused-vars、no-restricted-imports、no-restricted-syntax、RuleTester、eslint-plugin、eslint-config、FlatCompat、context.getScope is not a function、ESLint 10。

eslint-docs 是什麼?

這項技能涵蓋 ESLint 10.14.0,所有內容均基於官方文件 https://eslint.org/docs/latest/。它專注於與習慣不同的部分:flat config 的陷阱、令人意外的預設值、已移除的 API,以及文件推薦的模式。對於任何使用 ESLint 10(或正在從 eslintrc 遷移至此版本)的開發者來說,此技能至關重要,且支援所有官方文件提及的平台。它能協助使用者撰寫正確的 eslint.config.js、有效運用 CLI 與 CI、編寫自訂規則與外掛,並利用 Node.js API 進行整合。每個參考檔案中的論點結尾都標明其出處頁面,確保資訊可追溯。技能結構包含快速規則、舊版模式對照表,以及依任務分類的參考檔案,讓導覽更直觀。

ESLint 10

此技能涵蓋 ESLint 10.14.0,內容基於 https://eslint.org/docs/latest/。它專注於與習慣不同的部分:flat config 的陷阱、令人意外的預設值、已移除的 API,以及文件推薦的模式。每個參考檔案中的論點皆附有來源頁面。

如何導覽

  1. 閱讀下列快速規則。它們能抓住最常見的錯誤。
  2. 根據結尾的表格,開啟與任務相符的其中一個參考檔案。
  3. 當程式碼使用 .eslintrc、env、context.getScope() 或 FlatESLint 時,請先閱讀 references/migration.md。

快速開始

npm init @eslint/config@latest
// eslint.config.js
import js from "@eslint/js";
import globals from "globals";
import { defineConfig, globalIgnores } from "eslint/config";

export default defineConfig([
  globalIgnores(["dist/"]),
  {
    files: ["**/*.js", "**/*.mjs", "**/*.cjs"],
    plugins: { js },
    extends: ["js/recommended"],
    languageOptions: { globals: { ...globals.browser } },
    rules: { "no-unused-vars": "warn" },
  },
]);
