Description

Hello, welcome to the ‘Mastering Live(View) programming in Go’ course. With this course you are going to add a value to your existing Go Lang knowledge by getting familiar with several web development techniques known as a 'LiveView' programming model introduced within a last several years. We will focus on several topics popular when building web applications and we take a look on how to implement those features using a Live(View) techniques where JS usage is not needed or minimized at least. We are going to see how Live(View) programming approach makes web app development easier to do a more solution oriented. What is LiveVew programming approach / model?LiveView provides rich, real-time user experiences with server-rendered HTML. The LiveView programming model is mostly declarative: instead of saying "when event ABC happens, change XYZ on the page", events in LiveView are managed by handlers bound to event id. Once the state changes, LiveView will re-render the relevant parts of its HTML template(calculate diff) and push it to the browser, which updates itself in the most efficient manner. This means developers write LiveView templates as any other server-rendered HTML and LiveView does the hard work of tracking changes and sending the relevant diffs to the browser using websocket communication. This approach was widely popularized by Phoenix Framework and there are implementations for many major languages or platforms.Topics covered by this course:During a course we create basic web application in Go Lang with Live(View) approach. Main topics include:LiveView inspired programming - technical infoKey Live(View) concepts explainedThermostat - interactive application without JSImplementation of Pub/Sub communicationEnhancing thermostat - implementation of chat, clock, JS hooksLive(View) in popular frameworksIntegration of Live(View) application with NATS serverImportant part of this course is to realize 'what we don't need to do' when using Live(View) approach. Simplification can be huge and old saying that 'the best code is the code you don't have to write' proves here.Summary:The goal of this course is to make a guidance in Live(View) programming world. We use pragmatic approach by building real applications and exploring Live(View) programming model in practical way.GitHub repository:The source code is available through the link attached to the last lecture in this course. You can clone the repo and use the code snippets we are building in this course.
