Configure channel in Perl 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
Example configuration file with all three channel types:
{
"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:
You can configure the communication channel in Perl app in many different ways using Javonet.withConfig(...)
.
Instead of providing only a configuration file path, you can also pass:
- Perl 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 Perl object, or a JSON string depending on your use case. Below you can see a code example demonstrating how to load configuration from Perl object source.
