I checked the haxe official examples. While npm install and npm start worked fine locally. But when I tried to put them on my hosting's Vps it gave me this error:

[root@server colyseus-official-examples]# npm start

Hi @vishwasgagrani!

By the error message, it seems that devDependencies listed under package.json were not installed during npm install:

sh: ts-node-dev: command not found

If you use npm install --only=dev the development dependencies should be installed as well.

Let me know if that works for you!

Tried using -only=dev , but does not seems to solve the problem. Same error again. It is asking for peer dependencies though.

npm install --only=dev
npm WARN @colyseus/social@0.10.9 requires a peer of express-jwt@^5.3.1 but none is installed. You must install peer dependencies yourself.
npm WARN colyseus-examples@1.0.1 No repository field.

Anyway I looked into package.json and saw this list:

"@types/cors": "^2.8.6",
"@types/express": "^4.17.1",
"copyfiles": "^2.4.1",
"rimraf": "^2.7.1",
"ts-node": "^8.1.0",
"ts-node-dev": "^1.0.0-pre.63",
"typescript": "^3.4.5"

And after installing ts-node-dev using:
npm i ts-node-dev --save-dev

I see the server running at 2567
Listening on ws://localhost:2567

Got it working for now. Thanks.
