【问题描述】：

是否有任何方法可以 lint 或以其他方式调试 types 文件？

我有一个我所有类型的 index.d.ts 文件，但它似乎在启动时使我的应用程序崩溃。

使用 tsc 和一些基本选项可以正常工作使用tslint 工作正常。但是使用 webpack 编译器运行时出现以下错误。

文件内容很多但基本如下。我之前在导出枚举时遇到了一些问题，但基本上没有得到任何我能理解的实际错误。

// we SEND to Boto
export enum MsgTypeOut {
  TEXT = 0,
  IMAGE = 1,
  URL_LINK = 2,
  FILE = 3,
}

export interface BotoTextMsg {
  chatId: string
  messageType: MsgTypeOut.TEXT
  token?: string
  payload: {
    text: string
  }
}

webpack 配置几乎是基于 create-react-app 的香草。

const fs = require("fs")
// const path = require("path")
const NodemonPlugin = require("nodemon-webpack-plugin");

const nodeModules = {};
fs.readdirSync("node_modules")
  .filter(function (x) {
    return [".bin"].indexOf(x) === -1;
  })
  .forEach(function (mod) {
    nodeModules[mod] = "commonjs " + mod;
  });

module.exports = {
  entry: "./server/server.ts",
  output: {
    filename: "server.js",
    // path: path.join(__dirname, "/build"),
  },

  externals: nodeModules,

  // needed to fix https://github.com/webpack/webpack/issues/1599
  node: {
    __dirname: true
  },

  module: {
    loaders: [
      {
        loader: "ts-loader",
        test: /\.tsx?$/,
      },
    ],
  },
  plugins: [new NodemonPlugin()],
  resolve: {
    extensions: [".webpack.js", ".web.js", ".ts", ".tsx", ".js"],
  },
  target: "node",
};

【解决方案1】：

对于任何观看的人，该错误与导入 enums 有关。

您可以从types.d.ts 文件中导出enum...但它不会导入并以这种奇怪的方式炸毁。
