pnpm db:up
pnpm db:migrate
pnpm dev:mcp供前端直接对接的只读接口:
GET /api/proposals:按阶段、版本、状态和关键词检索GET /api/proposals/{id}:读取提案详情与 READMEGET /api/changes:读取一天、一周或一个月内的变化GET /api/health:API 健康检查
查询参数、响应结构和校验规则以 OpenAPI 文档为准。请求日志由 Hono logger 输出, 输入由 Zod 在数据库查询前校验。
服务启动后会立即同步一次 TC39 数据,随后每 24 小时同步;本地调试可设置
SYNC_ON_START=false。绑定到 0.0.0.0 或 :: 时必须通过逗号分隔的
ALLOWED_HOSTS 显式配置公开域名,可用 ALLOWED_ORIGINS 限制浏览器来源。
提案元数据来自 https://tc39.es/dataset/proposals.min.json,README 来自各提案
仓库。同步会校验官方 Schema 指纹和实际消费字段;上游契约变化或数据校验失败时,
日志会输出 tc39_dataset_schema_changed 或
tc39_dataset_validation_failed,本次同步不会写入数据库。
