Progressive Web Apps (PWAs) have gained significant attention since their introduction in 2015 due to their ability to leverage web standards and APIs like Service Workers and Web App Manifests, offering notable advantages over traditional mobile apps. The Ionic team, fully invested in the PWA trend, has developed a comprehensive resource called "The Architect’s Guide to Progressive Web Apps" to assist developers and digital architects in understanding and implementing PWAs effectively. This guide provides practical advice on deploying PWAs as part of a broader app strategy, highlighting key resources needed for development. With predictions from firms like Gartner suggesting that by 2020 half of all mobile apps could be PWAs, and major brands like Twitter and Pinterest investing heavily in them, the guide aims to furnish a solid foundational understanding for those new to the technology. The document promises to evolve with advancements in PWA techniques and invites feedback to ensure it remains a relevant and useful resource.
