Application hot deployment method, device and system

The invention discloses an application hot deployment method, device and system. According to the invention, when an updated data resource is detected, the page displayed by a browser can be updated in dependence on the updated data resource. Relative to an application module or a file, the granularity of the data resource is smaller, thus, compared with the prior art, the application hot deployment method is advantaged in that synchronization of finer-granularity data resources can be achieved, furthermore resource synchronization time delay can be reduced; when an updated data resource is detected, the page can be updated in dependence on the updated data resource immediately, the resource synchronization time delay can be further reduced, and the user experience is improved. 本申请公开了种应用热部署方法、装置和系统。本申请中，当检测到有更新的数据资源时，可根据该更新的数据资源更新浏览器显示的页面。方面，由于数据资源相对于应用模块或文件来说，其颗粒度更小，因此与现有技术相比，本申请实施例可以实现更细粒度的数据资源同步，进而可以降低资源同步时延；另方面，当检测到有更新的数据资源时，可立即根据该更新的数据资源更新页面，因此更进步地降低了资源同步的时延，提高用户感受。
