Svelte-Calculator-App

Goal

The goal of this project was to expand my frontend skills using another JavaScript framework (Svelte) to amplify my toolset.

This project was a challenge from Frontend Mentor.

Here I try focus on the logic of the app and handle basic operations of a basic calculator.

• Handle components
• Folder structure
• Svelte stores
• Testing with Jest and Testing-Library

Stack

This project use the default template for Svelte apps. The framework lives at https://github.com/sveltejs/template.

• Svelte
• Javascript
• HTML5, CSS3
• Node
• Jest, Testing-Library
• Vercel (deploy).

Commands

Dev

yarn dev

Starts the site in development mode.

Navigate to localhost:5000. You should see your app running.

By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the sirv commands in package.json to include the option --host 0.0.0.0.

If you're using Visual Studio Code we recommend installing the official extension Svelte for VS Code. If you are using other editors you may need to install a plugin in order to get syntax highlighting and intellisense.

Building and running in production mode

To create an optimised version of the app:

npm run build

You can run the newly built app with npm run start. This uses sirv, which is included in your package.json's dependencies so that the app will work when you deploy to platforms like Heroku.

Single-page app mode

By default, sirv will only respond to requests that match files in public. This is to maximise compatibility with static fileservers, allowing you to deploy your app anywhere.

If you're building a single-page app (SPA) with multiple routes, sirv needs to be able to respond to requests for any path. You can make it so by editing the "start" command in package.json:

"start": "sirv public --single"

Deploy

This app was deployed at Vercel.
