@snailycfx/nexus-transformer

TypeScript compiler transformer for @snailycfx/nexus.

Automatically injects event parameter metadata at compile time, enabling @EventHandler() to resolve event types without manual configuration.

Installation

npm install @snailycfx/nexus-transformer
npx ts-patch install

Setup

Add the transformer to your tsconfig.json:

{
    "compilerOptions": {
        "plugins": [
            { "transform": "@snailycfx/nexus-transformer" }
        ]
    }
}

How it works

The transformer scans your code at compile time for methods decorated with @EventHandler() and injects a NexusMetadata.define() call with the event class type automatically.

Before:

@EventHandler()
public onWaveStarted(event: WaveStartedEvent): void {
    print(event.getWave())
}

After (generated):

NexusMetadata.define("paramtypes", [WaveStartedEvent], target, "onWaveStarted")
@EventHandler()
public onWaveStarted(event: WaveStartedEvent): void {
    print(event.getWave())
}
