Question

我有一个带接口的配置变量。

//I declare my interface

interface ServerConfiguration {
  development: {
    db: {
      url: string,
      user: string,
      password: string,
    },
    webServer: {
      port: number;
      rootPath: string;
    }
  };
}

//I declare a variable that uses that interface

const config: ServerConfiguration = {
  development: {
    db: {
      url: "someUrl",
      user: "myuser",
      password: "mypassword",
    },
    webServer: {
      port: process.env.PORT || 9001,
      rootPath: rootPath,
    },
  },
};
// I export my variable
export  {config};

之后我导入它并尝试创建一个旨在使用该配置的函数

// I import my variable
import  config  = require( "./config");


// I create a function that will consume a variable that complies with that interface
function initializeDatabase(config: ServerConfiguration) {
//do stuff
}

我在这里得到错误＆＃34;找不到名称＆＃39; ServerConfiguration＆＃39;＆＃34;，出了什么问题？

Answer 1

在这里我得到错误“找不到名字'ServerConfiguration'”，出了什么问题？

单独导出每件事

export interface ServerConfiguration {
// also 
export const config: ServerConfiguration = {

并导入

import  {config,ServerConfiguration} from "./config";

使用类型信息导出typescript变量
