SvelteKit VS jest

Svelte Kit for the fullstack framework It has first class support for Cloudflare Pages Svelte is a very elegant framework, and Svelte Kit is a very good meta-framework for Svelte. Svelte was probably the reason that…

This AI-powered Story Card Maker is built as a SvelteKit application with Typescript. Using Flowbite Svelte component library, the whole application was laid out. The layout for the Story Card (emulating the size of a postcard - 4" x 3") is created as an HTML Canvas using Fabric.js.

These adapters, for example, were built by the community: https://github.com/sveltejs/kit/tree/master/packages/adapter-vercel https://github.com/nuxt/vercel-builder If somebody builds a working one for Angular Universal, we will gladly add it to our Framework Presets → https://vercel.com/docs/concepts/deployments/build-step#framework-preset.

UPDATE: If you liked this project and are curious to see what it might look like as a SvelteKit app, check out this blog post by Tim Smith where he converts this existing app over.

I've played around with several platforms in the last year or so. I've landed on the following setup that works very well for me and ticks all your boxes:

A SvelteKit[0] app hosted on Cloudflare pages. The repo is hosted on GitHub and hooked up to the Cloudflare Pages app [1]. On PRs, I get preview environments. On merge, the changes get deployed to my "production" website. I write blog posts and other content in markdown, which is then processed by mdsvex[2] with very minimal setup.

Mostly, my requirements were more focused around getting the actual framework, hosting, etc. out of my way so that I could focus on writing. Gatsby and Next.js were too configuration heavy and turned me off once I scratched beyond the surface.

Behind the scenes is a simple Sveltekit-powered server function to fetch a Spotify client token then find a user's recommendation playlist and its track information. A Deno edge function to performs this data fetch and renders server-side Svelte.

It’s 2024, and you are about to start a new project. Do you reach for React, a framework you know and love or do you look at one of the other hot new frameworks like Astro, Enhance, 11ty, SvelteKit or gasp, plain vanilla Web Components?

From part 0 to part 4, we built out CryptoFlow's backend service. Though we can quickly use Postman, VS Code's ThunderClient or automated tests to see the endpoints working easily, this isn't all we want. We want to actively interact with the backend service via some intuitive user interface. Also, a layman wouldn't be able to "consume" the service we've built in the last parts. This article introduces building out the user interface of the system. We will be using SvelteKit, a framework that streamlines web development, and TailwindCSS, the utility-first CSS framework. Let's dig in!

Jest

you have selected a testing framework. In my case, it's Jest with Supertest

Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.

Jest (https://jestjs.io/)

console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

Note: I will be using Jest as testing framework throughout the examples.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.

Jest is a well-regarded JavaScript testing framework primarily designed for React applications, although its utility extends to projects using Babel, JavaScript, Node, Angular, and Vue. Created by Facebook, Jest emphasizes ensuring the correctness of JavaScript codebases. It allows developers to write tests with a familiar, feature-rich API, making the testing process swift and enjoyable​​.
