🌊 Improving Single Executable Application Building in Node — First introduced two years ago, Node has a (still experimental) feature to build single executable applications that can be deployed to machines that don’t have Node installed. This week’s Node.js 25.5 release, with its --build-sea flag, moves the final injection step into Node itself, eliminating the need for external tooling and turning what was a multi-step, low-level process into a single command.
