Real-World Svelte

Lifecycles in Svelte

Svelte is a frontend framework. You can use Svelte to build websites and web applications. A Svelte application is made up of components. You write a Svelte component within a file with .svelte extension. Each .svelte file is one Svelte component.

When you create and use a Svelte component, the component goes through various stages of the component lifecycle. Svelte provides lifecycle functions, allowing you to hook into the different stages of the component.

In this chapter, we will start by talking about the various lifecycles and the lifecycle functions in Svelte. With a clear idea of lifecycles in mind, you will then learn the basic rule of using the lifecycle functions. This is essential, as you will see that this understanding will allow us to use the lifecycle functions in a lot of creative ways.

This chapter contains sections on the following topics:

  • What are Svelte lifecycle functions?
  • The rule of calling lifecycle functions
  • How to reuse and compose lifecycle functions

Technical requirements

Writing Svelte applications is very easy and does not require any paid tools. Despite the added value of most paid tools, we decided to use only free tools to make the content of this book available to you without any limitations.

You will require the following:

Description

Svelte has quickly become a popular choice among developers seeking to build fast, responsive, and efficient web applications that are high-performing, scalable, and visually stunning. This book goes beyond the basics to help you thoroughly explore the core concepts that make Svelte stand out among other frameworks. You’ll begin by gaining a clear understanding of lifecycle functions, reusable hooks, and various styling options such as Tailwind CSS and CSS variables. Next, you’ll find out how to effectively manage the state, props, and bindings and explore component patterns for better organization. You’ll also discover how to create patterns using actions, demonstrate custom events, integrate vanilla JS UI libraries, and progressively enhance UI elements. As you advance, you’ll delve into state management with context and stores, implement custom stores, handle complex data, and manage states effectively, along with creating renderless components for specialized functionalities and learning animations with tweened and spring stores. The concluding chapters will help you focus on enhancing UI elements with transitions while covering accessibility considerations. By the end of this book, you’ll be equipped to unlock Svelte's full potential, build exceptional web applications, and deliver performant, responsive, and inclusive user experiences.

I switched from React to Svelte 4 a few months ago, and this book has been an incredible resource. It explains complex problems exceptionally well, and I was pleasantly surprised by its clarity. I absolutely loved it. The author is truly talented. Thank you!

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
