Standardjs 在使用时没有未使用的变量

问题描述

在我的 Typescript React 项目中，我定义了:

导出类型 NavState = {mounted: boolean }

然后在我的组件中我使用了如下主题:

import { NavState } from '../../models/nav'类 Nav 扩展了 React.Component{状态:NavState = {安装:假}}

但我在导入中为 NavState 设置了红色下划线，它说:

'NavState' 已定义但从未使用.(no-unused-vars) 标准 (no-unused-vars)

在我的 package.json 中有这个:

 "标准": {忽略": ["node_modules/**",**/__生成__/"],"parser": "@typescript-eslint/parser",插件":[@typescript-eslint"]}

而我的 vs-code settings.json 是这样的:

{standard.autoFixOnSave":真，标准.启用":真，"standard.run": "onType",标准.验证":[{ "language": "javascript", "autoFix": true },{ "language": "javascriptreact", "autoFix": true },{ "language": "typescript", "autoFix": true },{ "language": "typescriptreact", "autoFix": true }]}

为什么 Standardjs 无法理解我使用了类型别名?我该如何解决?

解决方案

这应该可以解决问题:

import { NavState } from '../../models/nav'//eslint-disable-line

注意导入行上的注释.

In my Typescript React project, I defined:

export type NavState = { mounted: boolean }

and then in my component I used theme like:

import { NavState } from '../../models/nav'

class Nav extends React.Component<any, NavState> {
  state: NavState = {
    mounted: false
  }
}

but I got red underline for NavState in my import and it says:

'NavState' is defined but never used. (no-unused-vars)standard(no-unused-vars)

In my package.json I have this:

  "standard": {
    "ignore": [
      "node_modules/**",
      "**/__generated__/"
    ],
    "parser": "@typescript-eslint/parser",
    "plugins": [
      "@typescript-eslint"
    ]
  }

and my vs-code settings.json is like this:

{
  "standard.autoFixOnSave": true,
  "standard.enable": true,
  "standard.run": "onType",
  "standard.validate": [
    { "language": "javascript", "autoFix": true },
    { "language": "javascriptreact", "autoFix": true },
    { "language": "typescript", "autoFix": true },
    { "language": "typescriptreact", "autoFix": true }
  ]
}

Why Standardjs can't understand that I used a type alias? and how can I fix it?

解决方案

This should do the trick:

import { NavState } from '../../models/nav'  //eslint-disable-line

Notice the comment on the import line.
