Use Service Workers to Turbocharge Your Web Apps “You have made an excellent decision in picking up this book. If I was just starting on my learning path to mastery of Progressive Web Apps, there are not many folks I would trust more to get me there than John.” —Simon MacDonald, Developer Advocate, Adobe Software developers have two options for the apps they build: native apps targeting a specific device or web apps that run on any device. Building native apps is challenging, especially when your app targets multiple system types—i.e., desktop computers, smartphones, televisions—because user experience varies dramatically across devices. Service Workers—a relatively new technology—make it easier for web apps to bridge the gap between native and web capabilities. In Learning Progressive Web Apps, author John M. Wargo demonstrates how to use Service Workers to enhance the capabilities of a web app to create Progressive Web Apps (PWA). He focuses on the technologies that enable PWAs and how to use those technologies to enhance your web apps to deliver a more native-like experience. Build web apps a user can easily install on their local system and that work offline or on low-quality networks Utilize caching strategies that give you control over which app resources are cached and when Deliver background processing in a web application Implement push notifications that enable an app to easily engage with users or trigger action from a remote server Throughout the book, Wargo introduces each core concept and illustrates the implementation of each capability through several complete, operational examples. You’ll start with simple web apps, then incrementally expand and extend them with state-of-the-art features. All example source code is available on GitHub, and additional resources are available on the author’s companion site, learningpwa.com.

From the depression of the 1890s through World War I, construction tradesman held an important place in San Francisco's economic, political, and social life. Michael Kazin's award-winning study delves into how the city’s Building Trades Council (BTC) created, accumulated, used, and lost their power. He traces the rise of the BTC into a force that helped govern San Francisco, controlled its potential progress, and articulated an ideology that made sense of the changes sweeping the West and the country. Believing themselves the equals of officeholders and corporate managers, these working and retired craftsmen pursued and protected their own power while challenging conservatives and urban elites for the right to govern. What emerges is a long-overdue look at building trades as a force in labor history within the dramatic story of how the city's 25,000 building workers exercised power on the job site and within the halls of government, until the forces of reaction all but destroyed the BTC.

Originally published in 1983, The Making of Community Work is the outcome of a two-year study of community work in the United Kingdom. The main purpose of the study was to review the development of community work, and to suggest some of the issues in practice and training that might be important in the 1980s. Much of the first part of the book is taken up with the emergence of community work as an occupation; David Thomas tries to clarify its contribution to a number of political and social processes, and to define community work in a way which distinguishes it from other kinds of interventions. The second part of the book deals with training, research, literature and employment in community work; it includes a review of college and field-based training opportunities, and a critical discussion of the state of theory and ideology in the occupation. It was hoped it would be an important source of ideas and inspiration for the years ahead. It was the first major review of community work since its re-discovery in the 1960s; it will still be of interest to all those involved in community work, or wishing to understand its influence on other professions. The book was intended for fieldworkers, administrators, policy-makers, trainers and students in community work and in related occupations and disciplines. Thomas presents his ideas clearly, and his ability to look critically at some of the basic assumptions in community work makes for stimulating and enjoyable reading.
