Not on the current edition
This blip is not on the current edition of the Radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar Understand more

试验 ? 值得一试。了解为何要构建这一能力是很重要的。企业应当在风险可控的前提下在项目中尝试应用此项技术。

Offline first web applications provide the ability to design web applications for offline access by employing caching and updating mechanisms. The implementation requires a flag in the DOM to check whether the accessing device is offline or online, accessing local storage when offline, and synchronising data when online. All the major browsers now support an offline mode, which bootstraps the process of downloading and caching the resources such as HTML, CSS, JavaScript, images and other kinds of resources. There are some tools which help simplify offline first implementation such as Hoodie, and CouchDB also offers ability to work with a locally deployed application on a local data storage.
