@endel said in colyseus.js: server error: registeredHandler.klass is not a constructor:

Or by exporting the room usin

I'll try it the week end and come back to you later.
Thx for the help so far.

@diederik-van-remoortere

You must use typescript, I tried with babel but it was wrong.
In my repo I forgot to remove babel from the package.json

Sorry for the late reply!

I just finished a project where i'm able to run client but having .klass issue ...

please use develop branch

here it is :
https://github.com/erochOnGit/nodeGame

If you are not able to run it properly tell me i'll help you

@endel i did this it's not correct ?

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es6",
    "noImplicitAny": false,
    "sourceMap": true,
    "outDir": "build"
  },
  "exclude": [
    "node_modules",
    "**/*.spec.ts",
    "**/*.test.ts"
  ],
  "include": [
    "src/**/*.ts"
  ]
}

EDIT : I have the same error when i add "target": "es2015", to my tsconfig.json.

Hi there ! I finally succeed at running my server and my client with webpack and typescript ... but now i have a wierd error in chrome :

colyseus.js: server error: registeredHandler.klass is not a constructor

Does any one know what is it and where is it from...

I googled it and i found NOTHING it's scare me a lot ...

I found the problem by myself ... i was using colyseus server side

Hello it's my first topic here if there is rules don't hesitate to tell me :

I'm compiling my react with webpack but i would like to add colyseus ...

I run it on server side it's ok ... but when i add it to the client side it's crashing :

import React, { Component } from "react";
import ReactDOM from "react-dom";
import * as Colyseus from "colyseus"

class Salut extends Component {
    constructor(props) {
        super(props)

        this.state = {
            clientId: null
        }
    }

    componentDidMount() {
        this.client = new Colyseus.Client('ws://localhost:4000')
        this.room = this.client.join('room')

        this.setState({
            clientId: this.client.id
        })
    }

    render() {
        const { clientId } = this.state

        return (
            <div>
                Salut {clientId} !
            </div>
        )
    }
}



ReactDOM.render(
    <Salut />,
    document.getElementById("app")
);

here is my stack :

and here my webpack file :

const NodeExternals = require("webpack-node-externals");

const universalRules = [
  {
    test: /\.js$/,
    exclude: /node_modules/,
    use: {
      loader: "babel-loader",
      options: {
        presets: ["@babel/preset-env", "@babel/react"]
      }
    }
  }
];

module.exports = [
  {
    mode: "development",
    entry: "./src/web/index.js",
    output: {
      filename: "bundle.js",
      path: path.resolve(__dirname, "build")
    },
    plugins: [
      new HtmlWebpackPlugin({
        template: "src/index.html"
      })
    ],
    module: {
      rules: [...universalRules]
    },
    devServer: {
      contentBase: "./build",
      host: "0.0.0.0",
      disableHostCheck: true
    }
  }
];

I hope there is a way to fix it else i'll just open a bug on github ... it should be help full
