Erreur d'exécution lors de l'utilisation de socket.io dans la classe dactylographiée fournie par webpack

Question

J'essayais de faire usage de socket Web via socket.io dans un serveur de noeud écrit en tapuscrit avec expressjs. Livré avec webpack.

Le code serveur recherche comme suit:

import * as Express from "express"; 
import * as SocketIO from "socket.io"; 
import * as Http from "http"; 

const app = Express(); 

app.get("/", (reqest: Express.Request, response: Express.Response) => { 
    response.sendFile(process.cwd() + "/dist/index.html"); 
}); 

app.use(Express.static("./dist/")); 

const server = app.listen(3210,() => { 
    console.log("Listening to port"); 
}); 

const io = SocketIO.listen(server); 

La dernière ligne provoque les problèmes mentionnés plus tard.

Le webpack.config.js lui correspondant:

module.exports = [ 
    { 
     entry: "./server/main.ts", 
     output: { 
      path: "./dist", 
      filename: "server.js" 
     }, 
     debug: true, 
     devtool: "source-map", 
     module: { 
      loaders: [ 
       { 
        test: /\.ts$/, 
        loader: "ts-loader" 
       } 
       , { 
        test: /\.json/, 
        loader: "json-loader" 
       } 
      ] 
     }, 
     target: "node", 
     node: { 
      fs: "empty", 
      net: "empty" 
     } 
     ts: { 
      configFileName: 'server.tsconfig.json' 
     } 
    } 
]; 

Mais à la fin webpack imprime les avertissements suivants:

Est-ce que quelqu'un sait ce que j'ai mal fait?

Answer 1

import * as SocketIO from "socket.io"; 

devrait être:

import SocketIO from "socket.io-client";
