jest-light-runner VS vite

Hi! Christoph from Jest here. Your feedback is great, and 100% valid. Jest was built a long time ago when ES modules did not exist, and we are still carrying some of that legacy baggage around.

The good news is that we have never been shy about making breaking changes and we are working on cleaning the house and making many legacy components optional, all while bringing the existing community with us.

As for mocking, you don’t have to rely on Jest’s inbuilt mocking libraries and you can use the ones you like better.

If you care more about raw performance and ES module support and less about isolation, check out the jest-light-runner: https://github.com/nicolo-ribaudo/jest-light-runner

We also mentioned it in our Jest 28 blog post: https://jestjs.io/blog/2022/04/25/jest-28

I’m wondering if it’s time to consider taking a big step and making this runner the default, and give people the optionality of isolation. However, in my past experience at large companies (both first-hand and second-hand experience), the lack of isolation in tests led to major reliability problems with testing infrastructure. I’m still feeling like it’s the better default today, but maybe we should have a serious discussion about Jest’s next set of defaults.

For the frontend of "I Disappear," I leverage the automated build & deploy system provided by Netlify, which seamlessly integrates with Vite. This setup ensures that every deployment is optimized for performance, utilizing Vite’s modern build tools to enhance speed and efficiency.

Given our team's collective proficiency within the React ecosystem, we decided to leverage this expertise for our project. Initially, we contemplated utilizing Next.js; however, due to the limited practical experience with this technology among key engineers and the pressing timeline to develop the first prototype, we opted for a Single Page Application(SPA) approach. For bundling, we selected Vite, primarily due to its super fast build times, simplicity of configuration, and potential for a nearly seamless transition to server-side rendering.

We are continuing to add new project templates for various types of projects, and we've recently created one for the infamous combination of React with Vite tooling.

Vite focuses on providing an extremely fast development server and workflow speed in web development. It uses its own ES module imports during development, speeding up the startup time.

Vite and Next.js are both top 5 modern development framework right now. They are both great depending on your use case so we’ll discuss 4 areas: Architecture, main features, developer experience and production readiness. After learning about these we’ll have a better idea of which one is best for your project.

import { defineConfig } from 'vite' import react from '@vitejs/plugin-react-swc' import path from 'path' // https://vitejs.dev/config/ export default defineConfig({ plugins: [react()], server: { port: 3000 }, css: { devSourcemap: true }, resolve: { alias: { '~': path.resolve(__dirname, './src') } } })

I am currently utilizing Vite:

Without any adding any dependencies you can connect react props to raw css at runtime with nothing but css variables (aka "custom properties"). If you add CSS modules on top you don't have to worry about affecting the global scope so components created in this way can be truly modular and transferrable. I use this with vite.

Little confused as to why it has vite in it‘s name, it seems unrelated to https://vitejs.dev/
