snowpack VS jest

Once you build a simple Vite backend integration, try not to complicate Vite's configuration unless you absolutely must. Vite has become one of the most popular bundlers in the frontend space, but it wasn't the first and it certainly won't be the last. In my 7 years of building for the web, I've used Grunt, Gulp, Webpack, esbuild, and Parcel. Snowpack and Rome came-and-went before I ever had a chance to try them. Bun is vying for the spot of The New Hotness in bundling, Rome has been forked into Biome, and Vercel is building a Rust-based Webpack alternative.

Additional features for Bun include a transpiler and package manager. As hinted at in the name, it also includes bundling features, giving you the functionality that would otherwise require another tool, such as Snowpack or rollup.js. It also has a dead code elimination feature through its JavaScript minifier.

Even, there are several bundling tools available, including popular ones like Webpack and Snowpack.

once upon a time there was this thing called Snowpack: https://www.snowpack.devwhich had a lot of promises as vite (rollup w/ esm). So I migrated a project over from CRA to this thing.While startup speed was much much faster, it actually didn't make the app useable. I timed it meticulously for both CRA and snowpack build and found that the TTI was almost identical. I am not claiming the same to be vite but it's possible and I don't have a large app to prove it..

That reminds me, wasn't there a build tool called Snowflake?

Oh, it was called Snowpack [1]. And it's no longer being actively maintained. Yeesh.

Snowpack app - a single HTML page with Snowpack configuration

The first thing we need is a JavaScript project for our app. We'll use Snowpack as our bundler. Open a terminal located in a directory for the project and type npx create-snowpack-app react-couchdb --template @snowpack/app-template-minimal. Snowpack will create a skeleton for our React application and install all dependencies. Once it's done doing its job, type cd react-couchdb to get into the newly created project directory. create-snowpack-app is very similar to create-react-app in how it sets-up your project, but it's a lot less intrusive (You don't even need to use eject at any point).

Snowpack appears to be no longer maintained.

Before you get too deep into Snowpack, be aware that they recommend using other tools now because it’s no longer maintained.

There are several testing approaches you can take to ascertain the functionality of the auth API. One way would be to automate the testing using unit tests with tools like Jest and Supertest. Alternatively, you can make use of API clients like Postman or the Thunder Client VS Code extension to test the API.

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.
