Svelte 3 Up and Running

By: Alessandro Segala

Overview of this book

Svelte is a modern JavaScript framework used to build static web apps that are fast and lean, as well as being fun for developers to use. This book is a concise and practical introduction for those who are new to the Svelte framework which will have you up to speed with building apps quickly, and teach you how to use Svelte 3 to build apps that offer a great app user experience (UX). The book starts with an introduction to Svelte 3, before showing you how to set up your first complete application with the framework. Filled with code samples, each chapter will show you how to write components using the Svelte template syntax and the application programming interfaces (APIs) of the Svelte framework. As you advance, you’ll go from scaffolding your project and tool setup all the way through to production with DevOps principles such as automated testing, continuous integration, and continuous delivery (CI/CD). Finally, you’ll deploy your application in the cloud with object storage services and a content delivery network (CDN) for best-in-class performance for your users. By the end of this book, you’ll have learned how to build and deploy apps using Svelte 3 to solve real-world problems and deliver impressive results.

Linting and enforcing style conventions

Lastly, there's one more tool we will set up: ESLint. This is a linter, or in other words, a static code analyzer (that is, it inspects the code without running it) that is used for enforcing style conventions.

Tabs or spaces? Use semicolons or not? These are just two of the many style options developers have opinions about, sometimes really strong ones too! Regardless of what your preferences are, when you work in a team it's important to ensure that everyone writes code following the same styling conventions to keep the code base clean and readable.

ESLint is another open source tool that's almost ubiquitous among JavaScript developers, and it's a highly customizable linter. It allows you and your team to define rules for how the code should be written, and it can be used as part of your CI pipeline to enforce them. Even better, in many cases, ESLint can fix issues automatically, with the --fix switch!
