vscode里面报:‘xxx‘ is assigned a value but never used.解决办法

const setCurPage: React.Dispatch<React.SetStateAction<number>>

已声明"setCurPage"，但从未读取其值。ts(6133)

'setCurPage' is assigned a value but never used.eslint@typescript-eslint/no-unused-vars

出现这个报错是eslint导致的，所以需要修改eslint的配置：可以看官方文档提示no-unused-vars | typescript-eslint

只需要简单添加两个配置即可：

module.exports = {
  root: true,
  env: { browser: true, es2020: true },
  extends: [
    'eslint:recommended',
    'plugin:@typescript-eslint/recommended',
    'plugin:react-hooks/recommended',
  ],
  ignorePatterns: ['dist', '.eslintrc.cjs'],
  parser: '@typescript-eslint/parser',
  plugins: ['react-refresh'],
  rules: {
    'react-refresh/only-export-components': [
      'warn',
      { allowConstantExport: true },
    ],
    "@typescript-eslint/no-explicit-any": ["off"],
    "no-unused-vars": "off",
    "@typescript-eslint/no-unused-vars": "off"
  },
}

配置完如果不立即生效，可以重启vscode就可以了：就不会报错了，只会提示
