如何使用带有Loopback的TypeScript [英] How to use TypeScript with Loopback

问题描述

我使用Strongloop的Loopback作为REST框架和ORM。我想将TypeScript用于我的业务逻辑。但是，Loopback需要具有特定形状的JavaScript来支持其框架。例如：

I'm using Loopback from Strongloop as a REST framework and ORM. I want to use TypeScript for my business logic. However, Loopback requires JavaScript with a specific shape to support their framework. For example:

module.exports = function(Person){

    Person.greet = function(msg, cb) {
      cb(null, 'Greetings... ' + msg);
    }

    Person.remoteMethod(
       'greet', 
        {
          accepts: {arg: 'msg', type: 'string'},
          returns: {arg: 'greeting', type: 'string'}
        }
    );
}; 

什么是生成上述JavaScript代码的TypeScript代码？

推荐答案

什么是生成上述JavaScript代码的TypeScript代码？

What is the TypeScript code that will generate the above JavaScript code?

您可以直接使用此代码（JavaScript是TypeScript）。如果您对 module.export 感到好奇，可以使用TypeScript的 - 模块commonjs 编译标志来获取类型识别这样的方式：

You can just use this code as it is (JavaScript is TypeScript). If you are curious about module.export you can use TypeScript's --module commonjs compile flag to get that in a Typeaware manner like this:

function personMixin(Person){
    Person.greet = function(msg, cb) {
      cb(null, 'Greetings... ' + msg);
    }

    Person.remoteMethod(
       'greet', 
        {
          accepts: {arg: 'msg', type: 'string'},
          returns: {arg: 'greeting', type: 'string'}
        }
    );
};

export = personMixin; // NOTE!
