The boilerplate code to get started creating Cross-platform Desktop Apps with Electron and Svelte as front-end technology.
The aim of this project is to provide Web Developers using svelte the power to create cross-platform desktop apps using electron.
electron enables you to create desktop applications with pure JavaScript by providing a runtime with rich native (operating system) APIs. You could see it as a variant of the Node.js runtime that is focused on desktop applications instead of web servers.
electron-builder is used as a complete solution to package and build a ready for distribution (supports Numerous target formats) Electron app with "auto update" support out of the box.
electron-serve is used for Static file serving for Electron apps.
svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app. Instead of using techniques like virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes.
concurrently is used to run multiple commands concurrently.
wait-on is used as it can wait for sockets, and http(s) resources to become available.
Note: If you wish to use npm over yarn then modify package.json by replacing yarn with npm in electron-dev and preelectron-pack scripts.
But I strongly recommend using yarn as it is a better choice when compared to npm.
