✨ feat: 新增本地缓存功能 by imsyy · Pull Request #640 · imsyy/SPlayer
Summary of Changes
Hello @imsyy, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
此拉取请求的核心目标是为应用程序引入全面的本地缓存功能，以优化音乐播放和本地文件管理的性能和用户体验。通过将缓存逻辑抽象为独立的Electron服务，并将其集成到播放器和歌词管理中，显著减少了对网络资源的依赖，并提高了本地音乐库扫描的效率。此外，还扩展了本地音乐的浏览方式，新增了按文件夹分类的视图。
Highlights
- 本地缓存服务: 引入了全新的
CacheService和MusicCacheService，用于集中管理音乐和歌词的本地缓存。这包括缓存文件的写入、读取、删除、清空以及总大小计算，并支持根据大小限制自动清理旧缓存。 - 本地音乐库扫描优化: 重构了本地音乐扫描逻辑，现在使用
LocalMusicService进行管理，支持并发限制 (p-limit)、封面提取 (sharp)，并在扫描过程中通过 IPC 流式传输进度和批量歌曲数据，显著提升了用户体验和性能。 - 播放器缓存集成: 播放器现在会优先检查本地音乐缓存，减少网络请求。在线歌曲和解锁歌曲的 URL 都会尝试缓存到本地，并在网络请求失败时作为兜底方案。
- 歌词缓存: 歌词管理模块现在支持缓存原始的在线歌词数据（LRC 和 TTML 格式），避免重复下载，加快歌词加载速度。
- 新增本地音乐文件夹视图: 在本地音乐页面新增了按文件夹分类的视图，方便用户按目录浏览和管理本地歌曲。
- 设置项与用户体验改进: 新增了缓存大小限制设置，并优化了播放器进度条悬浮提示的显示逻辑。同时，本地音乐路径管理更加灵活，移除了默认音乐路径的特殊处理。
