Vue.js London

There's a lot to gain from adding animations to your site or app. Beyond their visual appeal, you can guide the user's attention, cover up slow to load components and elements, and reveal sections of a page without the user wondering where it came from. This talk will cover the built-in ways Vue.js helps you animate your site, and how for more complicated animations you can hook into third party libraries. It'll also cover the basics of animation itself—what to animate, what not to animate—and how you can use animations to enhance your website without harming the experience of people with disabilities.

UI components are built on user flows or state graphs. To manage these states, we usually resolved to boolean variables system like isLoading. But this proves to be buggy and hard to maintain as the codebase grows. There is a better solution. In my talk, we will explore how we can fully control our app's states and develop a more adaptive UI system to users' behavior while keeping the codebase scalable with state machines, in real time.

Most of the people in our industry know what Lighthouse or Page Speed Insights are and use them regularly. Unfortunately, most of them have no idea how they work which leads to terrible misconceptions and misunderstandings, especially for non-tech business owners. In this talk, I want to help everyone make better use of these tools by explaining how they work, what's their goal, and how to interpret the data to come to the right conclusions.

Building an online store these days is not an easy task. With so many competitors Time to Market is the key to success. That's why we decided to build an integration between Vue Storefront- Lightning-Fast Frontend Platform for Headless Commerce, and Vendure - modern, headless GraphQL-based e-commerce framework. Both tools are built using modern JavaScript stack (Nuxt.js and Nest.js) and have several out of the box integrations like search engines, CMS's, payments, and so on. Also, both projects have a huge community of Open Source contributors who support the development process. In this presentation, I will show you how fast you can create your store with VSF and Vendure.

Optimising developer experience with Nuxt 3 - a tour through the ways the new version of Nuxt will save time and make your life easier. We'll explore the new nitro-powered isomorphic fetch, dive into Nuxt 3's more powerful dynamic routing, and along the way tour a host of other features that will give you superpowers.

Dive deeply into the architecture of our massive Vuex store.

This solution will always be easy to scale, read, and maintain no matter how huge your app is.

Vue 3 may still sound new to many users, but it's actually been released for over a year already. How did Vue 3 evolve during this period? Why did it take so long for the ecosystem to catch up? What did we learn from this process? What's coming next? We will discuss these questions in this talk!

Explain about NuxtJS codebase refactor and challenges facing to implement Vue 3, Vite and other packages.

When we think about Vuex, Pinia, or stores in general we often think about state management and the Flux patterns but not only do stores not always follow the Flux pattern, there is so much more about stores that make them worth using! Plugins, devtools, server side rendering, TypeScript integrations, ... Let's dive into everything beyond state management with Pinia with practical examples about plugins and devtools to get the most out of your stores.

Topic: State Management.

Participants:

• Kia King Ishii – Vue.js Core Team. Author of Vuex ORM
• Eduardo San Martin Morote – Vue.js Core Team
• Vanessa Otto – Lead Frontend Developer at Zavvy, a co-host of the podcasts expect(Exception), Working Draft, and Ausbaufähig.

Frontend frameworks like Vue are vulnerable to unsanitized inputs to execute malicious code. The patterns that allow for this are generally understood, but there are still some cases when your apps might still be at risk. Learn how you can implement automated application security to keep your apps safe.

Developers often look at abstractions as being "the closer to the metal, the better," meaning that as abstractions become further removed from the lowest possible level, the more you give up in terms of performance and features. But abstractions work as a spectrum also. We'll look at how we can adjust our view of abstractions and what kind of examples we can use to better understand that abstractions have less to do with programming and more to do with where we deploy.

In this lightning talk, you will see: 1. The lack of visibility on Vue.js applications. 2. How to install the Sentry Vue.js SDK. 3. How you can use Sentry to identify errors and slowdowns within your Vue.js App.

Rust is a new language for writing high-performance code, that can be compiled to WebAssembly, and run within the browser. In this talk you will be taken through how you can integrate Rust, within a Vue application, in a way that's painless and easy. With examples on how to interact with Rust from JavaScript, and some of the gotchas to be aware of.

How many times did you implement the same flow in your application: check, if data is already fetched from the server, if yes - render the data, if not - fetch this data and then render it? I think I've done it more than ten times myself and I've seen the question about this flow more than fifty times. Unfortunately, our go-to state management library, Vuex, doesn't provide any solution for this.

For GraphQL-based application, there was an alternative to use Apollo client that provided tools for working with the cache. But what if you use REST? Luckily, now we have a Vue alternative to a react-query library that provides a nice solution for working with server cache. In this talk, I will explain the distinction between local application state and local server cache and do some live coding to show how to work with the latter.

Forms on the web have always been with us, yet it still feels like you always have to fight them to make validation work as you planned - and even with the significant improvements modern day libraries and frameworks give us, maintenance is mostly a hassle.

Vest is a new breed of form validations framework. It draws its syntax and style from Unit Testing frameworks like mocha or Jest (hence the name), which brings the elegance and declarative nature of these frameworks to the world of form validation, greatly reducing the overhead it takes to write, maintain and reuse validations in your JS apps.

This will be fast & furious! I will show you the fastest possible way to connect your Nuxt.js (Vue.js) project to the headless CMS and deploy it in seconds. You should know a thing or two about Nuxt.js, headless CMS in general or JAMstack as there will be no time to describe the concepts in detail. In the end, you will be furious how insanely good the JAMstack is!

Brief intro to the new features of Vue 3 and Vite, then focus on how those features / mindset affect the way we think of tooling and DX. Which leads to my Vitesse project and several unplugins that enhance the Vue developer experience even further (will do some short demos in between). Finally, introduce the ways to use those new features in the existing Vue 2 apps today and make the migrations easier.

Vue.js is a frontend framework. But the different modules, such as the reactivity engine can be imported on its own. Let's have some fun and explore possible use cases for Vue reactivity in the backend.

A CI/CD pipeline seems straightforward to implement and maintain. Yet it can often quickly become a tedious time sink and a source of universal frustration on many teams. From flaky builds, to long running builds, to flaky long running builds, the sources of frustration are endless. With the goal to ship more and faster as well as to compete in an ever changing industry, we can (and must) do better.

This talk will cover best practices for performance, stability, security, and maintainability of CI/CD pipelines, each supported with practical examples and counterexamples and tailored towards Vue.js developers.

Migrating to Vue 3 can be an important task (depending on your project's size). At Crisp, we recently migrated our app (250K lines of code) from Vue 2.6 to Vue 3.2 in about 2 weeks.

In this talk, we will share our learnings so you can benefit from our experience. We will talk about:

• The major differences between Vue 2 and Vue 3
• Dilemmas we've encountered and how we dealt with them
• Vue 3 migration strategy

What is the best way to structure a Vue.js application so that it can scale to meet all your users' needs ? There are multiple patterns established by the Vue community and the programming community at large that can be adopted in order to make your codebases more predictable, maintainable, and extendable.

The Vue 3 Reactivity and Composition API offers developers flexible techniques to work with reactive data. They enable a new and modern approach to handling State Management. Developers can now effortlessly implement local and global stores. Vuex has been one of the most used First-party plugins for Vue 2. Let's have a look at the advantages and tradeoffs of using Composables instead of Vuex.

Table of Content:

• Using Vue 3 without Options API
• Local and global state management with Composables
• Vuex-like store using provide/inject

With the introduction of Composition API into the Vue ecosystem, many are curious as to what they should pick. Options API? Composition API? Which is best? What are the tradeoffs? In this talk, we'll examine the two approaches so that you can make the right decision for your app.

On Stackoverflow, people usually do have the exact same struggles daily. Let me quickly review most of them and give you some solutions on how to solve them. On top of giving you tips on how to solve your bugs faster!

The web is an ever-changing platform and so are the websites we create. With new technologies and possibilities come new challenges for both developers and SEOs. In this session, we will talk about how developers and SEOs can become a team and solve challenges together. We will look into a few scenarios where this collaboration can bring success to a project.

Forms can be hard in frontend. Whether your forms are simple or complex, they share common pain points like value tracking, user interactions, validation, and submission. We will look at how vee-validate helps you address those issues, and how to apply progressive enhancements to your forms and input components.

Migrating your Vue 2 app over to Vue 3 doesn't have to be painful. This talk walks you through the process.

The Jamstack way of building the web is highly optimized for speed and performance. This is because the assets required to build Jamstack sites are pre-generated at build time and readily available to users.

However, this introduces a huge overhead for developers and enterprises building large sites as the build times can quickly get out of hand.

Lately, we've seen new patterns and techniques emerge from the community that solves this overhead in very practical ways.

In this session, I'll go over these patterns (Sharding, ISR, DPR, DSG) and show our viewers and 2million+ other Jamstack developers how to leverage them to build large sites without the overhead on lengthy build times.

Vite is a new build tool, created to make web developers of any kind happier and more productive. Vite is created by Evan You and significantly improves the frontend development experience.

In this talk you will learn what Vite is, why it is so great, and why you want to use it ASAP. You will also learn how to use Vite with Vue.js or React, and what Vitepress is and how to use it.

Alex Kyriakidis, founder of Vue School, will also answer the most frequently asked questions around Vite, including production use, Vite and test runners, what it means for Nuxt, and many more.

Learn about the newest features coming to the next version of the framework. See how the core team approached porting Vuetify from Vue 2 to the Vue 3 composition api. Preview updates to core features such as the new layout system, improved testing methodologies, expanded customization options, updates to css utility classes, and much much more.

With Chakra UI, we are able to override component styles to express custom design systems with accessible Vue components. This talk explores the new theme API in v1 and how you can use it to quickly build custom UIs for your application.

Whether you're creating niche content or building a website for a client you must have your Nuxt project ready to support any SEO technique. Alba will present us the resources that can help your website to grow in search engines and how to implement them in Nuxt.
