Easy-to-use modern TypeScript framework for building many kind of applications.

import { Alepha } from "alepha";
import { describe, it } from "vitest";

describe("alepha.events.emit", () => {
  it("should handle errors with catch option", async ({ expect }) => {
    const alepha = Alepha.create();

    alepha.events.on("echo", () => {
      throw new Error("Error in echo");
    });

    await alepha.start();

    await expect(() => alepha.events.emit("echo", {})).rejects.toThrowError(
      "Error in echo",
    );

    expect(await alepha.events.emit("echo", {}, { catch: true })).toEqual(
      undefined,
    );
