Configure channel in GoLang app

Javonet allows you to reference and use modules or packages written in (Java/Kotlin/Groovy/Clojure, C#/VB.NET, Ruby, Perl, Python, JavaScript/TypeScript) like they were created in your technology.
If you have not yet created your first project, check Javonet overview and quick start guides for your technology. Javonet enables configuring the communication channel with foreign runtimes via a configuration file. Each runtime section (jvm, netcore, nodejs, python, ruby, clr, perl) can be configured independently with one of the supported channel types:

In-Memory Channel – high-performance, within-process communication

TCP Channel – for inter-process or remote communication over TCP

WebSocket Channel – ideal for browser-based or cross-platform communication

{
  "licenseKey": "your-license-key",
  "runtimes": {
    "jvm": [
      {
        "name": "default",
        "customOptions": "",
        "modules": "",
        "channel": {
          "type": "inMemory"
        }
      }
    ],
    "netcore": [
      {
        "name": "default",
        "customOptions": "",
        "modules": "",
        "channel": {
          "type": "tcp",
          "host": "127.0.0.1",
          "port": 8080
        }
      }
    ],
    "nodejs": {
      "name": "default",
      "customOptions": "",
      "modules": "",
      "channel": {
        "type": "webSocket",
        "host": "wss://127.0.0.1:443/ws",
        "port": 0
      }
    }
  }
}

To use this file, load it using:

package main

import (
	"fmt"
	Javonet "javonet.com/javonet"
)

var resourcesDirectory string = "."

func main() {
	_ = resourcesDirectory

  	// use Activate only once in your app
  	_, err := Javonet.Activate(activationcredentials.YourLicenseKey)
  	if err != nil {
  		fmt.Println("Error: " + err.Error())
  	}
  	
  	// set up variables
  	configFilePath := resourcesDirectory + "/channel-tests-config.json"
  	communicationChannel := Javonet.WithConfig(configFilePath)
  	// use communicationChannel to create runtimes to interact with
}
// use Activate only once in your app
_, err := Javonet.Activate(activationcredentials.YourLicenseKey)
if err != nil {
	fmt.Println("Error: " + err.Error())
}

// set up variables
configFilePath := resourcesDirectory + "/channel-tests-config.json"
communicationChannel := Javonet.WithConfig(configFilePath)
// use communicationChannel to create runtimes to interact with

Javonet can be used both in Node.js and in browser-based JavaScript environments.
When using Javonet.withConfig(...), you are not limited to providing a configuration file path — you can also pass:

JavaScript object – representing the configuration structure directly in code.
JSON string – containing the configuration as a raw JSON-formatted string. This flexibility allows seamless integration regardless of your runtime environment.
You can use configuration from a file, a JavaScript object, or a JSON string depending on your use case. Below you can see a code example demonstrating how to load configuration from JavaScript object source.
