Node.js 如何将VSCode Intellisense与transpiled TypeScript NodeJS类一起使用

因此，我有一个TypeScricpt Nodejs控制器，我使用以下脚本传输了TypeScript：

"scripts": {
    "build": "npm run clean && mkdir dist && tsc -p .",
    "clean": "rm -rf dist"
},

打字稿被传输了，但我面临的问题是。现在，当我测试传输的源代码时，我期待以下内容：

当我需要该类并尝试创建该类的新实例时，我希望看到所需的构造函数参数的提示

我希望当我使用例如

instanceObj.

编写任何东西之前，应该使用内置类方法提示我

当我在谷歌搜索时，我遇到了这样一个问题：

VS code不知道参数是什么，因为您没有任何类型定义，例如，在TypeScript synax中描述接口的.d.ts文件。

• 但后来我意识到，我有所有这些，但仍然没有按预期工作

我的控制器身份验证文件

我认为这是调用类或对象时的标准代码行为（我将省略代码中的登录，因为我避免使代码变长，但仅使用一种方法，我的问题应该是可重现的）

下面的代码是TypeScript类：

interface Auth {
  SignUp(request: Request, response: Response): Response;
  Login(request: Request, response: Response): Response;
}
class AuthController implements Auth {
  userModel: Model<Document>;
  userSession: Document;
  hashRounds: number;
  mailTransporterUser: string;
  mailTransporterPass: string;
  passwordLength: number;

  constructor(
    userModel: Model<Document>,
    userSessions: Document,
    hashRounds: number,
    mailTransporterUser: string,
    mailTransporterPass: string,
    passwordLength: number
  ) {
    this.userModel = userModel;
    this.userSession = userSessions;
    this.hashRounds = hashRounds || 15;
    this.mailTransporterUser = mailTransporterUser;
    this.mailTransporterPass = mailTransporterPass;
    this.passwordLength = passwordLength || 8;
  }

  SignUp(request: Request, response: Response) {
    const form: Formidable.IncomingForm = new Formidable.IncomingForm();

    try {
      form.parse(request, async (error, fields, files) => {
        if (error) {
          return response
            .status(500)
            .json({ msg: "Network Error: Failed to sign user up" });
        }

        const { username, email, password, verifiedPassword } = fields;

        if (!username || !email || !password || !verifiedPassword) {
          return response.status(400).json({ msg: "All fields are required" });
        }

        if (password.length < this.passwordLength) {
          return response.status(400).json({
            msg: `Password has to be at least ${this.passwordLength} characters long`,
          });
        }

        if (password !== verifiedPassword) {
          return response.status(400).json({ msg: "Password's do not match" });
        }

        const isUserAlreadyExisting = await this.userModel.findOne({
          email: email,
        });

        if (!isUserAlreadyExisting) {
          return response
            .status(400)
            .json({ msg: "Account with this email already exist" });
        }

        const salt: string = await Bcrypt.genSalt(this.hashRounds);
        const hashedPassword: string = await Bcrypt.hash(password, salt);

        const newUser = new this.userModel({
          username: username,
          email: email,
          password: hashedPassword,
        });

        const savedUser = await newUser.save();
      });
      return response.status(201).json({ msg: "Account successfully created" });
    } catch (error) {
      console.error(error);
      return response
        .status(500)
        .json({ msg: "Network Error: Failed to signup user" });
    }
  }
}

希望在这个问题上得到帮助，我真的不知道我在类文件中的这个问题哪里出了问题：

类AuthController实现了Auth{

，你的意思是在这个前面写

导出默认值

，您的意思是像

const AuthController=require（“/Auth”）

？为什么不使用标准的

import AuthController from“/Auth”

，当我使用require intellisense时无法给出提示，但使用import时效果很好。我相信这是因为require是动态的，所以它在运行时才知道类型。@Krispies对于我在问题中提到的第一个问题，我省略了某些代码方法，以避免这方面的冗长代码，我也省略了ed to

export defualt

…尝试同时使用ES6导入和ES5，但保持不变没有intellisense，我不确定，但我相信更多的是我这边的TypeScript配置，但我无法指出有什么错你能将整个项目放在github上吗？你可以省略任何敏感信息，而且.d.t都生成正确吗？你应该ldn不需要在问题中发布这些内容。@Krispies很抱歉延迟了一段时间的回复，所以你不会相信解决这个问题的方法就是将

类型

添加到

package.json

并将其指向我的

index.d.ts

文件，然后类文件中的一切都开始工作：

类AuthController实现Auth{

，你的意思是在前面写

export default

吗？当你说“当我需要这个类时”，你的意思是像

const AuthController=require（“/Auth”）

？为什么不使用标准的

从“/Auth”导入AuthController呢
