ts-jest VS vite

Argument of type X is not assignable to parameter of type 'never' #2610

First, you can't use jest right out of the box, becuase Jest does not support ECMA script nor Typescript. For that, you need to use another dependency like ts-jest, which is a wrapper of jest itself. And maybe even a Babel preset if I need it to work with Babel.. Let's see what we have to do to get this to work.

use ts-jest and set up Paths Re-Map

Jest's out of the box config for TS doesn't do any type checking. You can integrate https://kulshekhar.github.io/ts-jest/ or you can call ‘tsc’ yourself separately

ts-jest has had some strange performance issues and workarounds in the past, though I haven’t used it very recently so it might have fixed those by now.

Since we're working with TypeScript, we can use ts-jest, which conveniently brings Jest along for the ride:

I want to save you from manually copying the snippets one by one, so here is a Gist with the complete test file. This can be easily executed with Jest (or ts-jest for TypeScript).

See the Jest configuration docs to learn more about Jest configuration. ts-jest also has good documentation.

Using @swc/jest to compile code to CommonJS is much faster than babel-jest, ts-jest which have long cold starts when executing tests in a large project.

We'll use React with Vite, shadcn/ui (a collection of reusable components I have been wanting to try for a while), React Hook Form for form management, and Zod for schema-based form validation.

Recently, a ticket was added to our sprint with the goal of reducing packages with critical and high vulnerabilities in a legacy project. The task involved migrating a Vue 2 project using Vue CLI as the build tool to Vite.

Tools like Vite should be used to build React components and JSX into a javascript bundle that can be executed in the browser.

A simple React, Vite, and react-router setup can go a long way.
