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.

Adding requirements

Starting from the scaffolded project we created at the end of the previous chapter, we need to add a few modules from NPM that are specific to our journaling application. Additionally, we will need to add a pre-made script with functions that handle authentication and a style sheet with global rules.

Because these things are specific to our journaling application, they were not included in the scaffolding steps from the previous chapter, which were more generic for every application instead.

Launching the back-end service

In order for the following examples to work, you'll need to ensure that the API server is running on your laptop. Refer to the instructions in Chapter 2, Scaffolding Your Svelte Project for how to launch it.

Dependencies

Run the following command to add dependencies from NPM (because these modules are included in our application's bundle and not just used at build time, we are adding them as dependencies rather than devDependencies...
