Nginx反代Jsdelivr自建Npm和Github镜像加速服务

由于某些原因，jsdelivr项目的中国域名cdn.jsdelivr.net经历了备案注销，这直接导致了国内用户访问该服务时线路质量变得极不稳定。对于众多依赖jsdelivr作为静态资源加速服务的网站和应用而言，这意味着加载速度显著下降，稳定性也大打折扣。相比备案期间的表现，当前的服务水平确实难以匹敌。
值得注意的是，在构建自己的jsdelivr镜像时，建议同时配置防盗链措施，以保护您的资源免受未经授权的使用，从而确保仅限内部或授权用户能够享受加速服务。通过这样的策略，不仅能够有效提升用户体验，还能在一定程度上减轻原服务的压力，促进网络资源的合理分配与利用。
实施上述解决方案不仅能为您的用户提供更加流畅、稳定的访问体验，而且从长远来看，有助于提高您网站的整体性能表现及搜索引擎排名，进而吸引更多的流量与关注。
