Question

我正在尝试将通过初始化socket.io得到的io对象导出到打字稿中的路由器模块，我是从server.ts模块导出io对象还是在路由器模块中初始化socket.io？还是其他建议的方式？

我尝试过

Server.ts

export const io = socketIO.listen(server);

customer-router.ts

console.log(io)

计算为未定义。

Server.ts

import {Server, createServer} from 'http';
// Init express
const app = express();

// Setup socket.io
const server: Server = createServer(app);
export const io = socketIO.listen(server);

export default server;

Start.ts

import { logger } from '@shared';
// Start the server
const port = Number(process.env.PORT || 3000);
server.listen(port, () => {
    logger.info('Express server started on port: ' + port);
});

BaseRouter.ts

import CustomerRouter from './customers/Customers';

const router = Router();
const path = '/ChowApi';

// Add sub-routes
router.use(CustomerRouter.path, CustomerRouter.router);

// Export the base-router
export default { router, path };

Customer.ts

console.log(io)

export default { router, path };

我希望输出是io对象，但是实际输出是不确定的

有人帮助我解决了这个问题，以防万一有人碰到这个问题。

// server.ts

import * as socketIO from 'socket.io';
import BaseRouter from './routes/Base';

const server = createServer(app);
const io = socketIO.listen(server);

const baseRouter = BaseRouter(io);
app.use(baseRouter.path, baseRouter.router)


// BaseRouter.ts

import { Router } from 'express';

export const BaseRouter = (io) => {
  // Init router and path
  const router = Router();
  const path = '/ChowApi';

  // Add sub-routes
  const customerRouter = CustomerRouter(io);
  router.use(customerRouter.path, customerRouter.router);

  return {
    router,
    path
  };
}

export default BaseRouter;

// Customer.ts

const CustomerRouter = (io) => {

  // Init router and path
  const router = Router();
  const path = '/customers';

  return {
    router,
    path
  }
};

export default CustomerRouter;

我不知道为什么我没有想到这一点。
