Practical Svelte is for people who want to quickly create ecommerce sites that are efficient and fast, using the upcoming Svelte framework and associated tools.

This project-oriented book simplifies the setting up of a Svelte site as a starting point before beginning to explore the benefits of using Svelte in an ecommerce environment and developing it into an ecommerce offer that we can customize according to your needs. It will equip you with a starting toolset that you can use to create future projects, incorporate into your existing workflow, and that will allow you to take your websites to the next level.

Throughout this book, Ill take you on a journey through constructing the front-end UI for our example site. We will touch on subjects such as adding data sources, creating the catalog, and implementing a payment function and more showing you how easy it is to develop simple ecommerce sites that we can augment later quickly. With the minimum of fuss and plenty of practical exercises, well focus on topics such as managing data and state, styling, creating components, and more right through to producing the final result viewable from any browser!

Svelte uses nothing more than standard JavaScript, CSS, and HTML, three of the most powerful tools available for developers: you can enhance, extend, and configure your site as requirements dictate. With Svelte, the art of possible is only limited by the extent of your imagination and the power of JavaScript, HTML, and Node.js.

Practical Svelte gets you quickly acquainted with creating and manipulating ecommerce sites using tools familiar to all developers. Its perfect for website developers who are already familiar with JavaScript and are keen to learn how to leverage the Svelte framework. You may also be a developer for whom time is of the essence and simplicity is key; you need to produce efficient and properly optimized content in modern browsers using tools already in your possession.

Writing a book can be a long but rewarding process; it is not possible to complete it without the help of other people. I would like to offer a huge vote of thanks to my editors in particular, Nancy Chen and Louise Corrigan; my thanks also to Rami Morrar as my technical reviewer, James Markham for his help during the process, and others at Apress for getting this book into print. All have made writing this book a painless and enjoyable process, even with the edits!

My thanks also to my family for being understanding and supporting me while writing. I frequently spend lots of late nights writing alone, or pass up times when I should be with them, so their words of encouragement and support have been a real help in getting past those bumps in the road and producing the finished book that you now hold in your hands.

Lastly, it is particularly poignant that the book was written at a time when the world has faced global events of an unprecedented nature; it was too easy to think about those who lost the greatest thing we as humans could ever have. Having a project to work on no matter how simple or complex it might be helped me get through those tough times, and with the hope that we face a new, improved, and hopefully better future.

Wait, this new framework has a runtime? Ugh. Thanks, Ill pass.

Let me begin with a single fact: were shipping too much code to our users.

Yes, it might well be the case that tools, such as React and Angular, are all the rage nowadays. But most of them have one thing in common they each have a runtime library that must run when rendering websites using these tools. Sure, this might be a necessary evil when creating component-driven websites, but its okay, as everyone does it, right?
