javascript - 如何将类导出为根模块？

Question

我正在使用 TypeScript 构建 Node 项目。当 TS 将我的类编译为 JS 时，似乎导出了不需要的额外深度，请允许我说明一下。

TS

export class AppInfo {
    public name: string;
    public version: string;
    
    constructor(name: string, version: string) {
        this.name = name;
        this.version = version;
    }
}

生成的JS

var AppInfo = (function () {
    function AppInfo(name, version) {
        this.name = name;
        this.version = version;
    }
    return AppInfo;
})();
exports.AppInfo = AppInfo;

所以如果我想导入这个类，我必须这样做:

const AppInfo = require("./AppInfo").AppInfo;

var appInfo = new AppInfo(...);

如何告诉 TypeScript 直接导出我的类？像这样:

exports = AppInfo;

Answer 1

exports = AppInfo;

使用export =，如下所示:

class AppInfo {
    public name: string;
    public version: string;

    constructor(name: string, version: string) {
        this.name = name;
        this.version = version;
    }
}
export = AppInfo;
