Mastering Live(View) development in Go (GoLang)

Introduction:

Welcome to the ‘Mastering Live(View) programming in Go’ course. In this course, you will enhance your existing knowledge of Go Lang by delving into modern web development techniques inspired by the ‘LiveView’ programming model, which has gained prominence in recent years. Discover how to create interactive and real-time web applications in Go without relying heavily on JavaScript.

This course explores various web development topics and demonstrates how to implement them using ‘Live(View)’ techniques, minimizing the need for JavaScript. You’ll witness how the ‘Live(View)’ programming approach simplifies web app development, making it more solution-oriented and user-friendly.

What You’ll Learn:

• Create interactive web apps in GoLang
• Utilize websockets for modern client-server communication
• Develop UI-based applications with your existing GoLang backend skills
• Employ Push techniques to update users from the backend
• Create collaborative applications using the popular LiveView approach
• Accelerate your development process with modern programming techniques
• Craft highly maintainable and easily readable application code

What is the LiveView Programming Approach/Model? LiveView offers rich, real-time user experiences with server-rendered HTML. The LiveView programming model is primarily declarative, simplifying the development process. Instead of specifying detailed event-driven behavior, events in LiveView are managed by handlers bound to event IDs. When the application’s state changes, LiveView automatically re-renders the relevant parts of its HTML template, calculates the difference, and pushes these updates to the browser via websocket communication. This means developers can write LiveView templates like any other server-rendered HTML, with LiveView handling the complexity of tracking changes and efficiently updating the browser.

The Phoenix Framework widely popularized this approach, and implementations exist for various languages and platforms.

Topics Covered by This Course: Throughout the course, we create a basic web application in Go Lang using the Live(View) approach. Key topics covered include:

• LiveView-inspired programming, including technical insights
• Explanation of essential Live(View) concepts
• Building an interactive thermostat application without relying on JavaScript
• Implementation of Pub/Sub communication
• Expanding the thermostat application to include chat functionality, a clock, and JavaScript hooks
• Integration of Live(View) into popular frameworks
• Connecting a Live(View) application with a NATS server

An integral aspect of this course is understanding what you don’t need to do when utilizing the Live(View) approach. Simplification is a significant benefit, aligning with the adage that “the best code is the code you don’t have to write.”

Summary: This course aims to serve as a guide to the Live(View) programming world. We take a pragmatic approach by building real applications and practically exploring the Live(View) programming model.
