vitest VS vite

I will not go into detail about migrating your unit tests, as every project has its own test setup, and generalizing it would be very difficult. You can read and learn more about both of them in JEST docs and Vitest docs.

Using something like Vitest, Jest, or Mocha didn't work because:

However, I discovered a great combination that transformed my API call testing in TypeScript: Vitest and Mock Service Worker (MSW). Their well-crafted design makes them incredibly easy to use, enhancing the overall testing experience.

Next we’ll install Vitest and happy-dom to the project by running:

vitest is a testing framework similar to jest that integrates well with projects using Vite. It allows us to reuse plugins and configurations already set up in the vite.config.ts, making the test setup process easier.

For more detailed information on Vitest, refer to the official documentation. fficient Testing in Your React Projects with Vitest.

Vitest

Are you looking to migrate from Jest to Vitest for your React application? Look no further.

In addition to those tools, a new testing framework has emerged named Vitest. Vitest is built on top of Vite and has many exciting features to keep improving the overall developer experience for writing tests. This post shows you how to set up Vitest in your existing Angular project.

Initialize the Project Use Vite to create a new React app with this command:

In Vite, legacy browsers can be supported via the official @vitejs/plugin-legacy plugin, it also provides Browselist like configuration.

I have a silly react project that I’m working on that I made using create-react-app. By default, these kinds of projects build and run using react-scripts which uses webpack under the hood for building projects. Vite is generally known to be faster than Webpack ⚡ so I was curious about how to swap them.

Without a transpiler in the process, the jsx left as is: https://github.com/vitejs/vite/discussions/3448

We wanted to change the bundler to vite for two main reasons:

You can see all create-vite templates for other libraries. You can also learn more about vite in its documentation website.

After we have installed the Node environment, we can use Vite to install. Because the use of Vite has a higher version of Node.js requirements, so I recommend that you install a relatively new Node.js. currently I use the version for v18.15.0.

import { defineConfig } from 'vite' import riot from 'rollup-plugin-riot' export default defineConfig({ root : process.cwd() + '/client', plugins : [riot()], build: { minify : 'esbuild', /** https://vitejs.dev/config/build-options.html#build-minify */ target : 'esnext' /** https://vitejs.dev/config/build-options.html#build-target */ } })

As of this writing, initializing a Hattip project requires some manual commands. However, keep in mind that a zero-config development environment based on Vite is in the works.
