将 Cumulo Reel 的 server entry 迁到 Calcit 0.20.0 的 Node JS 路径,移除直接依赖 calcit-wss 与 calcit.std。新增窄的 WebSocket、文件、时间与退出信号宿主适配,保持数字 session ID、原始 Cirru EDN 消息、断线事件及备份路径语义。MD5 与随机颜色继续调用原有 npm 包,并验证返回值类型。

关联 calcit-lang/calcit#1315。

已验证:caps --calcit-version 0.20.0 --ci、默认与 server 入口严格检查、4 个 Calcit :tests、质量门禁、两个入口生成 JS、关键生成文件的 node --check。生成 JS 不再从应用命名空间引用 native-only calcit.std、calcit-wss 或 on-control-c。

仍待完成:本机 Yarn 的 npmMinimalAgeGate=1440 暂时隔离刚发布的 @calcit/procs@0.20.0。目前尚未更新 yarn.lock,也未执行 Node WebSocket 与持久化运行测试。因此此 PR 保持 Draft,不应合并。隔离期结束或得到明确许可后,更新锁文件、运行 CI 和实际消费场景,再处理 review comments。

English

Move Cumulo Reel's server entry to the Calcit 0.20.0 Node JS path and remove direct calcit-wss and calcit.std dependencies. Narrow WebSocket, filesystem, time, and shutdown host adapters preserve numeric session IDs, raw Cirru EDN messages, disconnect events, and backup-path behavior. The existing npm MD5 and random-color packages remain in use behind checked return values.

Related: calcit-lang/calcit#1315.

Verified: caps --calcit-version 0.20.0 --ci, strict checks for both entries, four Calcit definition tests, the quality gate, JS generation for both entries, and node --check for key generated files. Application namespaces no longer reference native-only calcit.std, calcit-wss, or on-control-c in generated JS.

Remaining: local Yarn enforces npmMinimalAgeGate=1440, which currently quarantines the newly published @calcit/procs@0.20.0. yarn.lock and live Node WebSocket/persistence tests are therefore pending. Keep this PR as a draft; do not merge until the lockfile, CI, live consumer acceptance, and review comments are complete.

Summary by CodeRabbit

  • Improvements
    • The server now runs on Node.js while preserving real-time messaging, client reconnections, and broadcasts.
    • Database persistence now creates missing directories, avoids rewriting unchanged data, and maintains dated backups.
    • Server startup, scheduled tasks, and interrupt handling now use Node.js runtime behavior.
  • Validation
    • Added checks for server startup and runtime behavior, including messaging, reconnections, persistence, and backups.

📝 Walkthrough

Walkthrough

The server entry now targets JavaScript/Node. Node host adapters provide WebSocket transport, persistence, scheduling, shutdown handling, local dates, hashing, and random colors. The change also updates dependencies and adds runtime tests to the compile workflow.

Changes

Node.js Server Migration

Layer / File(s) Summary
Node.js host contracts and package setup
docs/architectures/js-server-host.cirru, docs/js-server-migration.md, deps.cirru, package.json, .yarnrc.yml, .gitignore
The architecture specification and migration notes describe the Node.js host boundary. The dependency manifest and package configuration add or update the Node.js packages and compiler versions.
Node.js host adapters and server wiring
calcit.cirru, config/calcit-quality.cirru
The server entry uses Node.js host functions for startup, persistence, scheduling, WebSocket events, dates, hashing, and random colors. Client synchronization uses the new WebSocket adapter. Quality records include the new host functions.
Runtime validation and compile checks
scripts/server-runtime.test.mjs, .github/workflows/compile.yaml
Runtime tests check WebSocket events, broadcasts, reconnection, and persistence. The compile workflow checks and imports the generated server module, then runs the tests.

Merge Risk: 🔵 Low · up to e3992

If the port cannot be opened, the server may remain running without accepting clients. Handle startup failure before merging, or explicitly accept this operational risk.

当前状态:Actions 已通过(含 Yarn hardened install、生成服务端 node --check 与实际模块 import)。本地 Calcit/procs 0.20.0 的两个严格入口、4 项测试、质量门禁和页面构建也通过。

PR 仍保持 Draft:真实 WebSocket 连接已分配数字 SID,但文本消息暴露了上游 ws-edn 0.0.31 的 Buffer["to-string"]() 错误。消费者的 isBinary 布尔值误调用已在本 PR 修复;上游修复在 ws-edn #44,其 Actions 已通过。待该 PR 合并、主分支验证并发布 0.0.32 后,再升级本 PR 的 ws-edn 依赖并跑文本、二进制、断线及持久化实连验收,完成前不标记 Ready。

Runtime acceptance update: ws-edn #44 merged and 0.0.32 was released from green main CI. This PR now pins 0.0.32 and adds a Node 24 runtime gate. Locally, live WebSocket text, binary, broadcast, disconnect/reconnect with numeric SIDs, plus storage and dated-backup writes all pass. Calcit/procs 0.20.0 toolchain verification, both strict entry checks, four Calcit tests, quality gate and generated server syntax/import also pass. Latest Actions is green; no generated JS was committed. I am marking the PR ready for review. The separate whole-project calcit fix multi-entry preview limitation remains tracked in Calcit #1315.
