chore: update Node.js from 25 to 26, nightly workflow stays on 26.0.0-nightly by Copilot · Pull Request #594 · Hack23/game

Copilot · 2026-05-05T16:49:24Z

Fix CI failure: revert nightly to 26.0.0-nightly
docs/End-of-Life-Strategy.md:
- Fix Node 26 support dates: Bug Fixes Until → Oct 2027, Security Fixes Until → Apr 2029
- Fix forward-compat note: 26.0.0-nightly (not 27 nightly)
- Fix completed milestone text: uses 26.0.0-nightly, will switch to 27.0.0-nightly when available
- Fix Future Node 27 milestone: clarify it's non-LTS, only forward-compat workflow changes
- Fix version matrix: forward-compat row → "26 nightly (26.0.0-nightly)"
- Fix TypeScript → 6.0.3, @typescript-eslint → 8.59.2
docs/FUTURE_WORKFLOWS.md:
- Rewrite overview: Node 27 non-LTS; primary workflows/package.json/devcontainer stay on 26 LTS
- Restructure Phase 1: only test-and-report-latest-node.yml changes (26.0.0-nightly → 27.0.0-nightly)
- Remove Phase 2 items that incorrectly updated primary workflows to Node 27
- Update sed commands: Node 27 section has only the nightly switch; Node 28 LTS commands are clearly separated

- Update engines.node in package.json: >=25 -> >=26 - Update devcontainer image: javascript-node:24-trixie -> 26-trixie - Update devcontainer node feature version: 25 -> 26 - Update all GitHub Actions workflows to use node-version: "26" (test-and-report.yml, release.yml, codeql.yml, copilot-setup.yml, copilot-setup-steps.yml) - Update test-and-report-latest-node.yml to node-version: "27-nightly" - Update docs/End-of-Life-Strategy.md: Node 26 as active, 27 nightly - Update docs/WORKFLOWS.md: all version references to Node 26/27 nightly - Update docs/FUTURE_WORKFLOWS.md: rewrite as Node 27 upgrade plan

Applied all changes in commit 2c8822f:

Nightly version format: "27-nightly" → "27.0.0-nightly" (matching the old "26.0.0-nightly" pattern, 4 occurrences in test-and-report-latest-node.yml)
docs/WORKFLOWS.md: actions/setup-node@v6.3.0 → v6.4.0 (3 occurrences), TypeScript 6.0.2 → 6.0.3, reference label updated to "Node.js 27 upgrade plan (Node.js 26 upgrade completed)"
docs/FUTURE_WORKFLOWS.md: Roadmap row for Node.js 27 now correctly states the primary workflow stays on Node.js 26 LTS and only test-and-report-latest-node.yml moves to 27.0.0-nightly; also updated TypeScript/eslint versions and fixed chronological ordering of EOL rows

The workflow step table still documents actions/cache@v5.0.3 for the apt and Cypress caches, but the actual workflows are pinned to actions/cache v5.0.5 (by SHA). Please update these doc entries so they match the versions in .github/workflows/test-and-report*.yml.

@copilot analyse and fix Test and Report Latest Node / prepare (pull_request)
Test and Report Latest Node / prepare (...

Fixed in commit b04c378. The CI failure was Unable to find Node version '27.0.0-nightly' — Node.js 27 nightly builds don't exist yet (Node 27 is expected October 2026). Reverted test-and-report-latest-node.yml to "26.0.0-nightly" (4 occurrences), which tests against the latest Node 26 nightly patch builds and keeps the forward-compat workflow green. The docs have been updated to note that this will advance to 27.0.0-nightly once those builds are published.

+> **Note:** Node.js 26 is an even-numbered release that will graduate to **Active LTS in October 2026**. It was released on April 22, 2026. We use Node.js 27 nightly builds in the forward-compatibility workflow (`test-and-report-latest-node.yml`) to validate readiness for the next release.



+### ✅ Completed — Upgraded to Node.js 26: May 2026

-Node.js 25 receives its final bug-fix release around **April 1, 2026**. Security-only patches continue until **June 1, 2026**.
+All CI/CD workflows, devcontainer configuration, and `package.json` have been updated to Node.js 26. The forward-compatibility workflow (`test-and-report-latest-node.yml`) now targets Node.js 27 nightly.



 | Workflow | Purpose | Current Node Version |
 |----------|---------|----------------------|
-| `test-and-report.yml` | Primary CI — stable, production-ready | **25** |
-| `test-and-report-latest-node.yml` | Forward-compat — tests next version | **25** (will become 26) |

Applied all changes in commit 5651948:

docs/End-of-Life-Strategy.md:

Node 26 support dates corrected: Bug Fixes Until → Oct 2027 (end of Active LTS), Security Fixes Until → Apr 2029 (EOL)
Forward-compat note updated to 26.0.0-nightly (not 27 nightly)
Completed milestone text now says "currently uses 26.0.0-nightly — will switch to 27.0.0-nightly once builds are published"
Future Node 27 milestone: clarified as non-LTS; only test-and-report-latest-node.yml changes
Version matrix forward-compat row: "26 nightly (26.0.0-nightly)"
TypeScript → 6.0.3, @typescript-eslint → 8.59.2

docs/FUTURE_WORKFLOWS.md:

Overview rewritten: Node 27 is odd/non-LTS; primary workflows, package.json, and devcontainer remain on Node.js 26 LTS
Phase 1 now covers only the test-and-report-latest-node.yml nightly switch (26.0.0-nightly → 27.0.0-nightly)
Removed incorrect checklist items that would have migrated primary workflows to Node 27
Sed commands section: Node 27 has one command (nightly switch only); Node 28 LTS upgrade commands are clearly separated with a "DO NOT run for Node.js 27" note
