TypeScript 经常出现问题，并且更喜欢 import 而不是 require

只要有可能，我都会尝试使用import over require但在某些情况下这会破坏类型检查。处理这个问题的正确方法是什么？是否可以导入？不是全部require可以替换为import's?

Left: Property 'get' does not exist...

Right: import * as convict from "convict";代替require("convict");

Left:

"use strict";

import * as Busboy from "busboy";
import * as convcit from "convict";
import * as config from "./config";
import * as express from "express";
import * as helmet from "helmet";
import * as logger from "morgan";
import * as path from "path";

import * as requestDebug from "request-debug";
import * as requestJs from "request";

// [ts] Property 'get' does not exist on type 'typeof "PrizmDoc-Node.js-Sample/config"'.
if (config.get("env") !== "production") {
    requestDebug(requestJs);
}

...

Right:

//let convict = require("convict");

import * as convict from "convict";

const config = convict({
    "env": {
        "doc": "The application environment.",
        "format": ["production", "development", "test"],
        "default": "development",
        "env": "NODE_ENV"
    },

...

module.exports = config;

不幸的是，这是您的依赖项之一的类型问题，convict。看着@types/convict source:

https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/convict/index.d.ts#L122 https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/convict/index.d.ts#L122

他们使用导出定义export = ...，根据 Typescript 手册：

https://www.typescriptlang.org/docs/handbook/modules.html https://www.typescriptlang.org/docs/handbook/modules.html（参见“export =and import = require()“ 标题）

breaks import * from ...进口。所以，你有点卡在这一点上了。
