变更

趋势页(发现)新增「高级搜索 / Code Search」频道,基于 grep.app 公开仓库代码检索接口(前端直连,无需认证):

  • 匹配模式:模糊 / 全词 / 正则(RE2,互斥)+ 可叠加区分大小写
  • 关键词实时搜索(450ms 防抖,≥2 字符,AbortController 取消过期请求)
  • 仓库 / 语言 / 路径动态过滤器(facets 做选项、hits 做展示,勾选自动重搜)
  • 「只显示我收藏的仓库」开关(默认关,按 full_name 大小写不敏感本地过滤)
  • 结果卡:仓库 / 分支 / 语言 / 匹配数 + 消毒后 snippet(保留 mark 高亮)+ GitHub 文件链接 + Load More 分页
  • 新频道排除在自动拉取、全部刷新、仓库维度工具条之外;老用户持久化自动合并出新频道

文件

  • 新增:src/services/grepAppService.ts(含单测)、src/components/CodeSearchView.tsx(含单测)
  • 修改:DiscoveryChannelId += code-search、默认频道、各 discovery 状态 map、tooltip、发现页缓存清理、相关 fixture/测试期望

验证

  • npm run typecheck 通过;eslint 干净
  • 7 个测试文件 93 项通过(含新增 service 8 用例 + view 6 用例)
  • 接口实测:q=githubstarsmanager 返回 facets/hits 结构与文档一致(repo/path 为纯字符串,已做 {raw} 兼容);机房 IP 触发 Vercel Challenge,故采用浏览器直连

Summary by CodeRabbit

  • 新功能

    • 新增代码搜索频道,可通过 grep.app 搜索公共代码。
    • 支持模糊、全词和正则匹配,以及大小写、仓库、路径、语言和收藏仓库筛选。
    • 提供防抖搜索、分页加载、代码高亮和可访问的文件链接。
    • 支持筛选分面,并在搜索受限时显示可重试提示。
  • 改进

    • 代码搜索频道支持独立的加载状态、分页状态、滚动位置及缓存清理。

Changes

代码搜索频道

Layer / File(s) Summary
grep.app 服务与数据处理
src/services/grepAppService.ts, src/services/grepAppService.test.ts
新增查询 URL 构造、响应归一化、请求取消、429 识别、收藏过滤和 HTML 片段清理。测试覆盖查询参数、兼容格式、过滤和错误处理。
代码搜索界面与交互
src/components/CodeSearchView.tsx, src/components/CodeSearchView.test.tsx
新增 CodeSearchView,支持防抖搜索、模糊/全词/正则模式、大小写开关、分面筛选、收藏过滤、分页、结果链接和错误重试。
发现频道接入
src/types/index.ts, src/store/schema.ts, src/components/DiscoveryView.tsx, src/components/SortAlgorithmTooltip.tsx
新增 code-search 频道类型和默认配置。DiscoveryView 使用 CodeSearchView,并跳过通用自动加载、刷新和筛选控件。

In `@src/components/CodeSearchView.tsx`:
- Line 494: Update the pagination control condition in CodeSearchView so the
“load more” entry remains available when starredOnly is enabled, even if
visibleHits is empty; retain the existing visibleHits.length requirement when
the filter is disabled.

In `@src/services/grepAppService.ts`:
- Around line 196-211: Replace the regex-based sanitization in
sanitizeGrepSnippet with DOMParser-based recursive traversal that preserves only
the existing allowed tags and safe text/content, removing disallowed elements
and attributes including malformed or unquoted event-handler attributes before
HitCard renders the result. Add coverage for the compact div/onclick bypass case
while preserving the current sanitization behavior for permitted markup.
