๐ŸคŸ Lexe: Package a Node App into a Single Executable Node actually has a mechanism for creating single executable applications and there are numerous other tools to do it, but Lexe takes the approach of using Amazonโ€™s lightweight LLRT engine to make binaries of under 10MB in size. Note, however, "Lexe is not a drop-in replacement for Node.js. It only supports a subset of Node.js APIs." Ray-D-Song

Nodeโ€™s Fastify framework has a mature plugin for Vite integration (explained in detail here), including @fastify/react which just hit version 1.0 and makes it easy to create fast, featureful (though obviously less so than Next.js) React apps atop Fastify. How fast? Very, it seems. Jonas Galvez
