Transforming Little Engine into Epic Engine — Create React App to Vite Migration

Introduction If you've worked with React, you've likely encountered Create React App (CRA)—a command-line tool designed to simplify the process of bootstrapping new React projects. CRA provided a zero-config setup by bundling essential tools like Webpack, Babel, and ESLint, allowing developers to start coding immediately without dealing with complex configurations. However, as modern development practices evolve, CRA’s capabilities have become increasingly limited. According to the official React documentation: "Although Create React App makes it easy to get started, there are several limitations that make it difficult to build high-performance production apps. In principle, we could solve these problems by essentially evolving it into a framework." Why Migrate from CRA? At Playsimple, our internal dashboard (Little Engine) relied on CRA until now, but as our application scaled, we began facing several issues that significantly affected our development speed and efficiency. Some challenges faced using CRA:
