Mobile Offline

Mobile Offline is an advanced runtime environment for Lightning web components. Available only for mobile devices, it replaces the standard Lightning components runtime and augments it with features designed specifically for mobile and offline use.

With the power of Lightning Web Components (LWC), you can create custom apps and experiences that tailor the Salesforce Mobile App to your specific business needs. LWC represents the best of the Salesforce platform, bringing modern web standards in performant, modular components that are easy to create. The goal of Mobile Offline with LWC is to help you build mobile experiences that work regardless of network conditions.

• Briefcase Builder lets you define advanced data priming strategies, customized for the objects and records that your users need access to while offline.
• A new priming engine preloads records when you prepare to go offline.
• A durable on-device cache exists for primed records, including changes made while offline.
• Lightning Data Service (LDS) is enhanced to work seamlessly with primed records. While online, LDS uses the cache as a performance enhancer. While offline, LDS allows transparent access to existing, changed, and even new records.
