@vitest-evals/core

Shared primitives and JSON artifact schemas for vitest-evals.

This package owns dependency-light data contracts shared by the user-facing Vitest integration, GitHub reporter, and future report UIs. It validates Vitest JSON reports, reads task.meta.eval and task.meta.harness, preserves full normalized harness runs, and collects one or more JSON reports into a multi-run workspace model.

import {
  collectReportWorkspace,
  parseVitestJsonReport,
} from "@vitest-evals/core";

const report = parseVitestJsonReport(JSON.parse(rawJson));
const workspace = collectReportWorkspace(
  {
    report,
    source: "vitest-results.json",
  },
  {
    workspace: process.cwd(),
  },
);

Use this package when building report consumers that need the full JSON artifact shape, such as the GitHub reporter, local report UI, or static CI report exports. Vitest lifecycle APIs such as describeEval(...), matchers, and reporters stay in vitest-evals.

Node report consumers can use @vitest-evals/core/node for shared path, glob, directory, and JSON file readers without pulling filesystem APIs into the browser-safe main entry.
