Client sample

Using the WebSocket-client sample bundle

The WebSocket-client sample bundle in samples/websocket-client shows how to set up a simple WebSocket client that will ping a server every second.

Prerequisites

You will need a working nodecg-io installation. If you have non yet take a look at installation guide. You may need to install this bundle, so take a look at the “Try an included sample”-Guide. It will also tell you how to log in and how to use the GUI.

For simplicity's sake this sample will rely upon the websocket-server sample.

Configure the WebSocket-client sample bundle

Please set up the WebSocket-server bundle first and then follow these steps:

  1. In NodeCG, create a new ws-client service instance.

  2. Enter the address of the sample server. This has to be a URL following the pattern ws://localhost:<port>.

    {
    "address": "ws://localhost:7777"
}

    After entering it, click save.

  3. Set the sample's (websocket-client) dependency to be the newly created service instance (of type websocket-client).

  4. A websocket-client has been connected and the console should display if a ping is sent or a pong is received.
