@reionjs/vitest

Vitest helpers for Reion: boot a real HTTP server from reion.config.*, inject a small request client into tests, and tear down automatically.

Install

bun add -d vitest @reionjs/vitest

Peer dependencies: reion, vitest.

Setup with CLI

Use Reion CLI for automatic setup:

reion add -p @reionjs/vitest

This setup does:

• installs @reionjs/vitest (handled by reion add)
• installs vitest (unless you use --skip-install)
• creates vitest.config.ts if it does not exist
• sets package.json script: "test": "vitest run"

When creating vitest.config.ts, setup prompts whether to add alias config:

• optional @ alias (@ -> ./src) for projects using tsconfig paths

If vitest.config.ts already exists, setup leaves it unchanged.

Usage

import { describe, it, expect } from "@reionjs/vitest";

describe("API", () => {
  it("GET /api/hello", async ({ request }) => {
    const res = await request.get("/api/hello");
    expect(res.status).toBe(200);
  });
});

• Use describe / it from this package (not plain vitest) so the suite gets a Reion server from process.cwd() + reion.config.*.
• For custom setups, use createTestServer() and createRequestClient() directly.

See the docs: Plugins → Vitest helpers.
