![]() ![]() It has been an opensource project from the very beginning, and is rapidly gaining notariety in many programming communities. The project was unveiled at ElixirConf in 2019, and released in 2020 as a part of Phoenix 1.5. After years of building effective infrastructure with startling scalability and reliability, he was finally ready to attack LiveView. #PHOENIX LIVEVIEW ANDROID#He wrote a book called Metaprogramming Elixir, and then shifted his attention to the Phoenix framework. Look up flight status of any flight & see live flight status maps on iPhone Android BlackBerry Palm or any mobile phone with FlightViews real time flight. When Chris McCord - creator of Phoenix - moved from a Ruby consultancy to the Elixir community, he was looking for the kind of infrastructure that would let something like LiveView flourish. The end result is that the developer’s focus shifts from things that are difficult, like managing concurrency or IO, to something that programmers are good at, writing small functions to change state. Like the entire Elixir ecosystem, this means there is a learning curve, but great velocity gains to be had once you get used to it. Paying attention to directory structure and naming conventions is much more important than in other web app frameworks. You can strongly feel the Rails influence. The size of those diffs is affected by how you write your app. (That is to say, over a WebSocket.) Well, mostly automatically. Then, the user renders the data as a string, and any changes to the data structure automatically trigger a render. Phoenix is an opinionated framework with quite a bit of magic to it. Phoenix LiveView distinguishes itself from other 'server-side reactive' frameworks ¹ by automatically sending minimal diffs over the wire. Instead, LiveView lets a programmer build a data structure in memory. It takes traditional web development, which focuses on individual tasks that render HTML, and flips the model on its head. Handle On and Off Events Then to handle those inbound events, we need to define matching handleevent callbacks. It binds a click event to the button so when it’s clicked the event is sent via the websocket to the LightLive process. The LiveView project has swept through the Elixir community like wildfire. LiveView refers to the phx-click attribute (and others like it) as a binding. Phoenix is the web development framework for Elixir, and LiveView is a Phoenix service that allows interactive page flows without JavaScript. ![]() The updates will tentatively be compldted by Feb 1, 2021. #PHOENIX LIVEVIEW UPDATE#Then, we’ll update the written content and links. LiveView is built on top of the battle-tested Phoenix platform so it can reliably handle millions of concurrent websocket connections. We’re starting by updating all of the videos. NOTE! This version of the LiveView content is under development. ![]()
