From bbe810236e1c6134f17c07bdf8ea604819112487 Mon Sep 17 00:00:00 2001 From: Miguel Angel Simon Sierra Date: Sat, 1 Aug 2026 01:17:40 +0200 Subject: [PATCH] ci(studio): gate load, open-project time and eager bundle size Runs the two-arm load gate on the dev arm at CI budgets against a real 3,000-clip project generated at run time, plus the eager bundle byte check on every studio PR. The bundle check enforces a ratchet at 870,000B rather than the 600KiB target. The target needs a Node-only AST/DOM stack out of the browser bundle, which is its own unit; enforcing it now would mean a permanently red check, and a permanently red check gets muted. The ratchet cannot be regressed past and every run reports the remaining gap. --- .github/workflows/ci.yml | 68 +++++++++++++++++++ .../studio/src/lib/studioLoadBudgets.test.ts | 1 + packages/studio/src/lib/studioLoadBudgets.ts | 9 +++ .../studio/tests/e2e/studio-bundle-budget.mjs | 18 ++++- 4 files changed, 94 insertions(+), 2 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 110457f1cf..c608c98966 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -503,6 +503,74 @@ jobs: kill $SERVER_PID 2>/dev/null || true + studio-load-gate: + name: "Studio: load and open-project gate" + needs: [changes] + if: needs.changes.outputs.studio == 'true' + runs-on: ubuntu-latest + timeout-minutes: 15 + steps: + - uses: actions/checkout@34e114876b0b11c390a56381ad16ebd13914f8d5 # v4 + - uses: oven-sh/setup-bun@0c5077e51419868618aeaa5fe8019c62421857d6 # v2 + - uses: actions/setup-node@49933ea5288caeca8642d1e84afbd3f7d6820020 # v4 + with: + node-version: 22 + - run: bun install --frozen-lockfile + # vite.config.ts is loaded by Node and resolves workspace packages through + # their "node" export condition, so the dists must exist first. + - run: bun run --filter '@hyperframes/{parsers,lint,studio-server}' build + - run: bun run --cwd packages/core build + - run: bun run --cwd packages/core build:hyperframes-runtime + + # Cheap, no browser: runs on every studio PR.
