Optimizing Mobile Web Apps for Low-Bandwidth Networks

Short summary

Mobile web apps on low-bandwidth networks require architectural rethinking: use aggressive asset splitting and service-worker caching to eliminate unnecessary requests, and substitute system fonts for custom ones to prevent layout shifts. Performance must be a foundational design constraint, not a final-pass concern. The fastest request is the one never made—load functionality strictly on-demand.

• •Asset splitting and service-worker caching eliminate unnecessary network requests
• •System fonts prevent layout shifts better than custom web fonts
• •Performance optimization should guide design decisions from the start
