ASP.NET+Core+2+and+Angular+5-Packt+Publishing(2017).pdf下载

It's only been a year since I wrote ASP.NET Core and Angular 2, but it definitely feels a lot more, at least from a web developer's perspective. Modern web technologies are still improving at lightning-fast speed, with an increasing, perceptible, and measurable interest being in the client-side aspects of the game. Angular, React, and VueJS collected no less than 150,000 * questions in the latest 18 months, which is more than 250 per day--and the trend is still growing. That's to be expected, since most of the major conceptual changes that occurred between 2015 and 2017 have been hitting the clients way more than the servers; we switched from a reactive approach of doing stuff--that led us to build responsive, resilient, elastic, and message-driven Single-Page Apps (SPAs)--to a progressive way of seeing things--which materialized into Progressive Web Apps (PWAs). The change of perspective is slight, yet prominent; far from being a different paradigm, what we've seen was nothing less than the natural and inevitable evolution of the same original concepts. Compared to the SPA revolution that took place in 2015-2016, the rise of Progressive Web Apps is not a game-breaking event; we can say that PWAs inherit all the major concepts that were already part of the Reactive Manifesto and bring them further on with brand new features--such as Service Workers--that would not have been possible without some relevant client-side accomplishments such as HTML5, modern browsers, and ECMAScript 6. PWAs are a much expected improvement in the present that also emphasizes its increasing distance from the past. At the same time, PWAs are not meant to be the future, not because they won't become a standard--they definitely will--but because they will also improve and, eventually, collapse into something else. This is how the client side of the moon always worked and--hopefully--always will.
