Directly Implement the soap.ts as follow:
import * as express from 'express';
import * as http from 'http';
let soap = require('soap');

export class SoapServer {

    private server;

    constructor(listenPort: number, address: string) {
    }

    public async init()  {

    }

    public async start() {
        let soapService = {
            CalculatorService: {
                CalculatorPort: {
                    add: function(args) {
                        let n = args.a + args.b;
                        return { value: n };
                    },
                    subtract: function(args) {
                        let n = args.a - args.b;
                        return { value: n };
                    }
                }
            }
          };

        let app = express();
        let xml = require('fs').readFileSync('/Users/hluo/company/code/services.soapexport.auth/wsdl/calculatorService.wsdl', 'utf8');
        app.listen(3000, function(){
           soap.listen(app, '/calculatorService', soapService, xml);
        });
    }

}
