React + TypeScript + Vite + Vitest + jsdom + React Testing Library

This is an application developed to demonstrate technical proficiency in building and testing a React application.

How to run it?

• Run pnpm dev to run the application.

How to test it?

• Run pnpm vitest to run the unit tests.

Aplication stack

pnpm

• I choose pnpm as the package manager because its fast and disk-efficient. Instead of duplication dependencies in every project's node_modules folder, it downloads packages to a single global store and creates hard links to them.

Vite

• Vite is a fast frontend build tool that makes the development environment very fast and optimize the code for production.

React + Typescritp

• I didn't choose it, it's the required lib of the challenge. But it's curently my main stack so I can talk a little bit about it. React is one of the most used technologies of the world, it's very popular because of its ecosystem(community, libraries, tutorials and job opportunities), and versatility on creating applications as SPA's.
• Talking about Typescript, it's an open-source, statically typed superset of JavaScript developed by Microsoft that makes our loved JavaScript get typed strongly improving the code development experience.

Vitest + jsdom + React Testing Library

• Vitest was created to make testing just work for Vite apps. By building on top of Vite, Vitest natively understands your Vite config and is able to reuse the same resolve and transform pipelines.
• To simulate a browser and create an environment to test the application I choose jsdom, that is a library recommended by the vitest documentation.
• Testing JavaScript programs in simulated environments such as jsdom or happy-dom has simplified the test setup and provided an easy-to-use API, making them suitable for many projects and increasing confidence in test results.
• The last one but no less important, React Testing Library that was not a choice as well but its the most complete and common tool for testing React applications, providing tons of functions for manipulate and get TSX elements.
