Reactjs 如何在React应用程序中导入我的typescript文件中的js模块（具有绝对路径）？

我正在我的React应用程序中集成typescript，它有大量的代码。我在React组件上应用了一些应用程序级HOC，如下所示：

import React from 'react';
import HOC1 from 'app/hocs/hoc1';
import compose from 'recompose/compose;

class MyComponent from React.Component {
     ...component stuff...
}

export default compose(HOC1())(MyComponent);

但现在我在应用程序中添加了typescript，无论何时导入

import HOC1 from 'app/hocs/hoc1';

上面说

TS2307: Cannot find module 'app/hocs/hoc1'.

我不想将类型定义添加到所有HOC中。解决方案是什么？为什么会出现这个错误

[EDIT]我也在

tsconfig

中使用

baseUrl

。我的文件夹结构是

/Project/configs/tsconfig
/Project/src/app/hocs

在tsconfig中，我通过文档给出了

baseUrl

作为

。/src

另一次编辑 我的网页包配置如下所示：

    {
        test: /\.(t|j)sx?$/,
        loader: 'happypack/loader?id=jsx-without-proptypes',
        include: [
          path.resolve(__dirname),
          path.resolve(__dirname, '../src'),
        ],
      },

上定义的别名也没有起作用。

使用别名 要将导入映射到正确的文件，您需要使用webpack配置中的

config.resolve.alias

字段

在您的场景中，将出现以下情况：

const config = {
  resolve: {
    alias: {
      'app': path.resolve(__dirname, 'src/app/'),
    },
  },
};

我不是100%确定我做得对，但我也在tsconfig中指定

路径

键，如下所示：

"baseUrl": "./src",
"paths": {
  "@common/*": ["./common/*"],
  "@moduleA/*": ["./moduleA/*"],
  "@moduleB/*": ["./moduleB/*"],
}

---

而且似乎还可以

@

前缀只是我在

tsconfig.json

中区分模块和npm依赖项的一种方法，你是否有

“allowJs”：true

？此外，如果你要导入本地模块，你需要在路径中使用

/

来指定，例如

从“/app/hocs/HOC1”导入HOC1“允许“：true

在我的tsconfig中，没有任何方法可以代替导入所有内容，因为导入100个文件会使我在这里键入的内容相对混乱。我的代码中没有键入错误。@AjayGaur，它不编译吗？总是犯同样的错误？还是IDE是抱怨的对象？@AjayGaur，正如您在

src

上定义的

context

一样。如果

config.resolve.alias

mapping

'app'：“../src/app'

有效，您能试试吗？我的

tsconfig
