In plain English

Snowpack was a frontend build tool designed to make web development faster by using JavaScript's native module system (called ESM, or ECMAScript Modules) instead of bundling everything together like traditional tools do. Rather than combining all your files into one big package every time you save, Snowpack served each file individually during development, so the browser only reloads what actually changed. This meant the development server could start in under 50 milliseconds and changes appeared in the browser almost instantly. It was positioned as a lighter, faster alternative to webpack or Parcel for day-to-day development, with built-in support for TypeScript, JSX, and CSS Modules. For final production builds, you could still plug in a traditional bundler. However, Snowpack is no longer actively maintained as of April 2022 and is not recommended for new projects. Its successor and recommended alternative is Vite, which carries forward the same ESM-based philosophy with active development and a broader ecosystem.
