Best Practices for Organizing and Structuring Svelte Applications

This article provides guidance on best practices for organizing and structuring Svelte applications, including tips for modularization, code splitting, and managing state, with the goal of improving maintainability and scalability.

Introduction

When building a web application, it’s important to keep the codebase organized and structured in a way that is easy to understand and maintain. Svelte, a lightweight JavaScript framework, offers a variety of features and tools that can help developers to achieve this goal. In this article, we’ll explore some best practices for organizing and structuring Svelte applications.

Folder Structure

One of the first things to consider when building a Svelte application is the folder structure. A common approach is to have a top-level src folder that contains all of the application's source code. Within this folder, you can create subfolders for different parts of the application, such as components, pages, store, and assets.

src/
  components/
  pages/
  store/
  assets/

The components folder is where you'll store all of the reusable UI components that make up your application. These can include buttons, forms, and other elements that are used throughout the application.

The pages folder is where you'll store all of the application's pages. Each page should have its own subfolder, with a .svelte file for the markup, a .js file for the logic, and a .css file for the styles.

The store folder is where you'll store any state management code. This can include files that define stores using the writable() function, as well as any custom logic for handling actions and updates to the store.

The assets folder is where you'll store any static assets that the application uses, such as images, fonts, and other media.

Naming Conventions

When building a Svelte application, it’s important to use consistent naming conventions for files and components. One common approach is to use camelCase for file names and kebab-case for component names. This can help to make the codebase more easily readable and maintainable.
