Vue.js is a JavaScript framework for building user interfaces that has gained popularity recently. It is smaller in size than Angular and React but provides similar functionality like virtual DOM and one-way data binding. Vue.js applications can range from simple single-page apps to complex projects with nested components. Key aspects of Vue.js include reusable components, templates with directives like v-if and v-for, lifecycle hooks, and the use of Vuex for state management and Vue Router for routing. The ecosystem around Vue.js continues to grow with tools, libraries, and support from companies using it in production.
I talked about Vue.js at @agenciasomadev. In this talk I showed the basics about the Vue.js JavaScript Framework and it's simplicity. I hope you enjoy :)
Vue comes with a simple and minimalistic core that is perfect for simple, single page applications that don't require heavy overheads. Vue works primarily on the ViewModel with two-way data bindings and is designed to be simple and flexible, allowing developers to mold the layer as they see fit.

Creating Modular Test-Driven SPAs with Spring and AngularJSGunnar Hillert
Single-page Applications (SPA) are all the rage these days and with them there is an avalanche of new tools, libraries and frameworks we need to know. But what does this mean for us as Spring developers? In this session we will give you an overview of the current landscape and illustrate the choices the Spring XD team has made for its user interface. What do I use to write SPA applications? How do I integrate them into existing Spring-based backends? How do I build them? Can I integrate them into my existing Gradle or Maven build processes in order to achieve complete build automation? How do I integrate realtime messaging using Spring's SockJS/WebSocket support? In this talk we will answer these and many more questions. We will cover frameworks such as AngularJS, Bootstrap, RequireJS; tools like Bower, Grunt, Gulp; and also talk about testing using Karma and Protractor.
Introduction to web application development with Vue (for absolute beginners)...Lucas Jellema
In this slide deck I show you how you can easily and quickly create quite rich web applications with Vue 3 – without having to study complex concepts or understand many technical details. I have only recently learned how to work with Vue 3 myself and now is the best time for me to share my learning experience (and my enthusiasm) with you. I know what I found essential to understand and what most got me excited in these early steps (what was a little bit hard to grasp). I believe that I can present my steps and guide you to experience the same fun and have a similarly gratifying experience. I am not an expert in this subject – I have barely learned how to walk and that is why I can help you with these first steps with Vue.
In this deck, I do not explain how Vue works. I do not really know that. I will show you how to work with it and how to create web applications that are functional, appealing, fast and responsive.
The approach I am taking is straightforward:
• I will tell you a little bit about web development, browsers and reactive frameworks
• I will show the hello world of Vue applications
• I will explain about components and nesting, events, data binding and reactive behavior and demonstrate these concepts
• I will introduce Vue UI Component libraries – and with no effort at all we will launch our application to the next level – with rich components to explore, manipulate, visualize data collections
• We will publish the web application from our development environment to where the whole world could see it – using GitHub Pages
• As bonus topic – we discuss state management
At the end of this session you will be able to quickly create a simple yet rich web application with Vue 3. You have a starting point to further evolve your skills with the many online resources I am convinced that you will enjoy your newfound powers and the simplicity and power of Vue 3.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Summary
Got really popular at the beginning of 2017. Laravel community started pick it up at about 2016
It passed ReactJS in terms of “github” popularity stars (151k vs 140k) at the time of writing
It didn’t come up out of one of the big tech companies (Google, Amazon, Facebook). Evan You was at Google but it all started from the community effort
It’s a view!
Vue is a progressive framework for building user interfaces.
Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects.
On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.
It is in the same space on what react does. It is about what Angular 2 tries to do, but in a way easier format, although i didn’t tried it
The idea is that Vue is all about everything that is interacting to what people are seeing on the screen. How it appears there, in a nice unidirectional flow. Start from one place and you control everything that appears on the screen
You have a nice standard way of handling user interaction (click events,touch screen events, etc)
Vue also took advantage of loads of lessons learned from React. We got things like Virtual DOM. Virtual DOM is what makes single place apps way faster than it used to be. For example jQuery, if you have 500 items, and if you want to change something in them, you have to select all of them and modify that property for them, or destroying the elements and recreating them. Browser doesn’t like that. It is very slow
Virtual DOM makes it a lot faster by maintaining a model of what is already there and what it needs to do.
In the Vue instance here, we have the html part. The id which is the “app” id where the app is hooking into the element and thus everything inside the div is controlled by Vue.
When a Vue instance is created, it adds all the properties found in its data object to Vue’s reactivity system. When the values of those properties change, the view will “react”, updating to match the new values.
Although not strictly associated with the MVVM pattern, Vue’s design was partly inspired by it. As a convention, we often use the variable vm (short for ViewModel) to refer to our Vue instance.
When you create a Vue instance, you pass in an options object. The majority of this talk describes how you can use these options to create your desired behavior. For reference, you can also browse the full list of options in the API reference.
A Vue application consists of a root Vue instance created with new Vue, optionally organized into a tree of nested, reusable components. For example, a todo app’s component tree might look like this:
So the previous example looks just like HTML. What makes it special is this ID. This is the reference where Vue is hooking into the element and is controlling the entire nodes inside it.
If you have not used AngularJS before, you probably don’t know what a directive is. Essentially, a directive is some special token in the markup that tells the library to do something to a DOM element. In Vue.js, the concept of directive is drastically simpler than that in Angular. A Vue.js directive can only appear in the form of a prefixed HTML attribute that takes the following format:
Vue.js uses an HTML-based template syntax that allows you to declaratively bind the rendered DOM to the underlying Vue instance’s data. All Vue.js templates are valid HTML that can be parsed by spec-compliant browsers and HTML parsers.
Under the hood, Vue compiles the templates into Virtual DOM render functions. Combined with the reactivity system, Vue is able to intelligently figure out the minimal number of components to re-render and apply the minimal amount of DOM manipulations when the app state changes.
If you are familiar with Virtual DOM concepts and prefer the raw power of JavaScript, you can also directly write render functions instead of templates, with optional JSX support.
Vue components are a nice vue innovation where they do exactly what each developer knows: html css and javascript. So why not...put it all together and make it all together and make it all part of the view framework.
The idea in Vue is that you can combine all of them in a single Vue file ( might get some folks triggered about css being declared on a separate file but css is actually defined per component base). In react community and later angular they are kinda adopting react as well

What you can also do with a Vue component is take leverage of pre-processors. In the time between react and angular was first made, this hole eco-systems was made up, starting with say gulp, and then webpack and rollup and other pre-processors.The entire idea is that you are not writing code that is executing in the browser anymore. This means that you are a lot freer about the code that you want it to be structure the way you want it to be. There is no such way to have a .vue file be loaded in the browser, it is just source, not executable code.
Even though we are losing a bit of functionality with this, there are debuggers and tools that doesn’t tend to be a problem. React and Angular do the same thing, all modern web development runs through some pre-processor. That’s how we have typescript.
The batteries are all included. Because vue sits in the same place as react did at the view layer, it’s taken all the different lessons learned and it copied them.
Basically if you do something in react, you can do it in view. For example the flux related libraries for maintaining state.
Officially endorsed one: Vuex
Vue.js uses an HTML-based template syntax that allows you to declaratively bind the rendered DOM to the underlying Vue instance’s data. All Vue.js templates are valid HTML that can be parsed by spec-compliant browsers and HTML parsers.
Under the hood, Vue compiles the templates into Virtual DOM render functions. Combined with the reactivity system, Vue is able to intelligently figure out the minimal number of components to re-render and apply the minimal amount of DOM manipulations when the app state changes.
If you are familiar with Virtual DOM concepts and prefer the raw power of JavaScript, you can also directly write render functions instead of templates, with optional JSX support.
Vuex helps us deal with shared state management with the cost of more concepts and boilerplate. It's a trade-off between short term and long term productivity.
If you've never built a large-scale SPA and jump right into Vuex, it may feel verbose and daunting. That's perfectly normal - if your app is simple, you will most likely be fine without Vuex. A simple store pattern may be all you need. But if you are building a medium-to-large-scale SPA, chances are you have run into situations that make you think about how to better handle state outside of your Vue components, and Vuex will be the natural next step for you.
