用于打字稿的 eslint-plugin-jsx-a11y

Question

我正在尝试为我的打字稿反应项目设置，当我工作时它会给我 warnings/errors 如果我正在做一些不可访问的事情。我的编辑器已经给我列出错误，但我尝试设置 eslint-plugin-jsx-a11y，但我无法让它工作。

这是我的 package.json

中的 eslint 部分

  "eslintConfig": {
    parser: '@typescript-eslint/parser',
    "extends": [
      "react-app",
      "react-app/jest",
      "shared-config",
      "plugin:jsx-a11y/recommended"
    ],
    "rules": {
      "additional-rule": "warn"
    },
    "overrides": [
      {
        "files": [
          "**/*.ts?(x)"
        ],
        "rules": {
          "additional-typescript-only-rule": "warn"
        }
      }
    ]
  },

不确定我错过了什么。谢谢

你是什么意思就是无法正常工作？

从外观上看，我猜您缺少 plugins 密钥，该密钥是使用每个 eslint 任何给定插件所必需的 docs。

eslint-plugin-jsx-a11y 文档甚至在 usage 部分提到了这一点。

extends 键仅应用规则集，而 plugins 键使某些规则可用，请参阅更长的解释。

"eslintConfig": {
  "parser": '@typescript-eslint/parser',
  "extends": [
    "react-app",
    "react-app/jest",
    "shared-config",
    "plugin:jsx-a11y/recommended"
  ],
  "plugins": [
    "jsx-a11y"
  ],
  "rules": {
    "additional-rule": "warn"
  },
  "overrides": [
    {
      "files": [
        "**/*.ts?(x)"
      ],
      "rules": {
        "additional-typescript-only-rule": "warn"
      }
    }
  ]
}

If this doesn't work please elaborate on what isn't working or what errors you get.

首先让我们确保你拥有所有安装此模块

"devDependencies": {
"@types/eslint": "7.28.0",
"@typescript-eslint/eslint-plugin": "4.28.2",
"@typescript-eslint/parser": "4.28.2",
"babel-eslint": "10.1.0",
"eslint": "7.30.0",
"eslint-config-airbnb-typescript": "12.3.1",
"eslint-config-react-app": "6.0.0",
"eslint-plugin-flowtype": "5.8.0",
"eslint-plugin-import": "2.23.4",
"eslint-plugin-jest": "24.3.6",
"eslint-plugin-jsx-a11y": "6.4.1",
"eslint-plugin-react": "7.24.0",
"eslint-plugin-react-hooks": "4.2.0",
"eslint-plugin-testing-library": "3.10.2",
"eslint-webpack-plugin": "2.5.4",}

当你在 yow 脚本部分安装它们时，添加一个像这样的新道具

"lint": "eslint --config ./.eslintrc.js \"./src/**/*.ts\" \"./src/**/*.tsx\" --fix --color"

这是一个功能示例
