Become a ninja with Vue 3

This ebook helps you get the philosophy of Vue 3 (currently 3.0.2), the new tools (like ES2015, TypeScript, Vue CLI...), the essential libraries (vue-router, @vue/test-utils, axios...), and each part of the framework in a pragmatic way. You will be able to kickstart your project by the end of the reading, and build your amazing apps!

If you want to go further, a Pro Pack is available with exercises to understand each step of building an application. That means tons of pragmatic code samples, tests for each step, good practices for every common use-case, and save tens of hours on your next project!

All examples use TypeScript and the Composition API to build a complete application with a router, forms, HTTP calls, tests, etc.

Our experience with Vue.js

Accessible to anyone

The ebook is at a 'pay what you want' price, with a very low minimum, so everyone should be able to read it, from students to professionals. You can also give part of the price to sponsor the framework development team. A professional package is also available and includes exercises, with instructions, unit tests and solutions, and all what's needed to hit the ground running on your first app, saving you days of learning and mistakes.
We gave to this ebook the Ninja Squad touch: a subtle mix of light tone and professional content. You can have a feel of this touch by reading our blog or the free samples of the book.

In the book, we dive into

features

The Future of JavaScript


Vue.js apps can be written in plain old JavaScript but it is much better using the ECMAScript 6 features, or even better: the type-safety of TypeScript. Several chapters are dedicated to these topics, to understand them and write beautiful code.

features

Philosophy


Vue.js is a modern JavaScript framework supercharged with awesome features: we'll explore the templating syntax, architecture choices, routing, tests, forms, etc.

features

Best practices


This ebook and these exercises are the result of countless hours spent on different projects. They contain all the best practices we encountered. We would have saved so much time if we had that book when we started! We go over kickstarting, tests, code organisation, tips for production, and more!

features

Components


The whole framework is component oriented. Vue.js has an ecosystem of component libraries and plugins which grows every day. Who never needed a chart, a map, a timepicker or a data-grid?

features

Tests


As usual, we'll spend some time talking about tests and testing strategies. And if you choose the Pro Pack, you'll have dozens of unit and end-to-end test examples for every part of your app. This will make sure your code is robust and trustworthy!

features

Performance


The Vue.js team has done an incredible job performance-wise. We'll see how that works under the hood, what can we do to go further and produce blazingly fast apps.

The Pro Pack

Switch to second gear by building a real project, step by step!

Our ebook lets you learn all the features of the framework. But for Vue.js, we decided to go further to share our expertise, by selling a Pro Pack. The Pro Pack makes you create an application skeleton, craft your first components, routes and forms. And above all it teaches you how to write tests, how to handle secured HTTP calls when your user is authenticated, how to design a reactive application, how to integrate with CSS frameworks like Twitter Bootstrap, third party libraries like Moment.js, already available components, and how to design your own (like a chart for example). If you want to completely master the framework, and be able to throw yourself with confidence in any projects, the Pro Pack is for you.

The Pro Pack contains a set of exercises, allowing you to build the PonyRacer app from scratch, confronting yourself to all these common problems in modern JavaScript applications. For each step, you receive a set of instructions corresponding to one of the ebook chapter, and a set of unit and end-to-end tests to validate your code. A NodeJS module we wrote is here to help you analyze your code and compute your score. Your turn to solve the challenge with the help of our tips! When you're done, or if you're stuck, you can check the solution we made. Our platform allows you to follow your progress, and inform you when we update the exercises. You can then switch to this new version (for free), and start again where you stopped. It's a great way to see how the best practices evolve!

Exercises list

Here are all the lessons you can follow with the Pro Pack.

animated pony

For this ebook, we needed a demo app. We could have built another TO DO list, or chat app, or Reddit clone, like there are already hundreds of. But we chose ponies. Because everybody loves a pony (a real-life unicorn). You'll learn to build an application to bet on ponies races, but above all, you'll learn about all the use-cases you may need in a real Vue.js application.

You'll learn to build components, the use the new composition API, forms, to send data to a server, to manage authentication, to build routes, to react to events, and a lot more! Give a try to our amazing PonyRacer demo application. All the code samples of this ebook are based on this app. That's also the same app that you'll learn to code step by step, exercise after exercise, with our Pro Pack.

Frequently Asked Questions

Because you always have exotic questions in your mind: we're here to bring you peace with nice answers.

 Is this ebook for me?
This ebook is for everyone wanting to discover or deepen their knowledge of Vue.js. Beginner students, experienced developers, absolute fans of other frameworks (Angular, React), and seasoned Vue.js 2.x users, everyone has found something useful in it.
But if you're already deeply familiar with Vue.js 3.x, you won't probably learn that much, besides some tips and best practices learned from our experience.
But this ebook can also be a nice gift for a friend! ;)
 I've never used Vue.js 2.x. Am I gonna understand anything?
Of course! This ebook does not require any knowledge of previous Vue.js versions.
If we point out some differences with Vue.js 2.x, you'll learn to build Vue.js apps from nothing but JavaScript.
 Your book and your exercises are full of sample code. They will be quickly out-of-date, right?
We're test addicts. Every piece of code given as example is statically analyzed and unit tested. While writing this book, we could upgrade with every Vue.js release and quickly spot every breaking change. Thus, you can be assured that every piece of code is working, and that any following Vue.js release won't break anything.Same thing for the Pro Pack: the project is fully updated and regenerated on every Vue.js release, with each step automatically tested.
 Will this book be updated with upcoming Vue.js releases?
Yes. We update this ebook very regularly, by adding new chapters, rewriting some, and migrating everything to every new Vue.js release. These updates are free for any buyer. Have a look at the full changelog. The ebook is currently written for Vue.js 3.0.2.
 Can I read a sample chapter?
Yes, even several of them! \o/
You can grab them for download in every language available (English and French), and every format available (PDF, EPUB, and HTML).
And a nice way to taste our writing style is to have a look at our blog.
 Which tools are you writing this book with?
We're writing in Asciidoc, and we're using AsciiDoctor to generate all expected formats (PDF, EPUB, and HTML). A build based on Vue CLI analyzes every sample code, tests it, before embedding it in the ebook source.
 Why a digital book?
Without even mentioning trees sparing and easy logistic, we prefer a digital ebook over a physical book because we can easily update its content, might it be a typo or a new feature of the framework. Have a look at the full changelog.
 Why share the sales with the development team ?
Let's be clear: the ebook sales won't pay for the time of its writing, ever (every technical writer will say so).
But we are happy to sponsor, even modestly, the Vue.js development team. You can retribute the authors for their work, and optionally sponsor the framework development team, whatever the ratio you want.
 Do people buy this ebook? For real?
It's just the beginning, but we certainly hope so ! Many already bought and loved our previous books, in any case :) Already 507 people bought our ebook. You can look at our sales figures, they are completely public.
 Are the files DRM-protected?
Absolutely not.
 Can I reuse this ebook commercially?
No, this is the only restriction: you may not sell it and use it commercially.
 And do I really have to provide my credit card number to a bunch of ninjas?
Pay what you want does not mean free!
You can pay with PayPal, or with your card through Stripe. In any case, we never have access to your card details.
 What do you do with my personal data?
We only collect your email, that we need to send you your purchase, your invoice, and an email from time to time to notify you when we update the ebook. You can ask us at any time to delete your email from our database (but we won't be able to send you the updates anymore).
 My company/accountant/spouse needs an invoice, are you providing one?
Yes, you'll get an invoice for every purchase. You'll even be able to customize the invoice with your own company details if you need to.
 My download link has expired. I lost my download link. What can I do?
Don't panic. Click here, enter the email address you used to buy the ebook, and you will receive a fresh download link by email. That also allows you to get the most recent version of the book.
 I would like to download the latest ebook version. It's possible, right?
Yes! Enter the enter the email address you used to buy the ebook on this page, and you will receive a new download link by email, pointing to the latest ebook revision of the book.
 Is it possible to try the Pro Pack for free?
Yes, it is. Just go to the Pro Pack platform, where you can register for a demo and enjoy the whole experience with the 6 first exercises for free.
 I want the Pro Pack for my whole team, is it possible?
Sure! You just have to input the needed quantity when buying, and you'll get an appropriate discount. Then, you can register your team members one by one, to open their access to the online platform. If you need further explanations, send us an email at contact at ninja-squad.com to talk about it.
 Do you offer trainings?
Thanks for asking! :) Yes, we offer trainings on Vue.js for every level, but also on other topics that might interest you.
