Node.js 25.5.0 (Current)

Notable Changes

Streamlined building process of Single Executable Applications (SEA)

This release introduces a new --build-sea command-line flag that simplifies the process of building Single Executable Applications (SEA) using Node.js.

Previously, SEA generation involved copying the executable, generating the preparation blob with --experimental-sea-config, and injecting the blob into the copy using nodejs/postject. With the new --build-sea flag, these steps are now consolidated into a single step available from Node.js core.

$ echo 'console.log("Hello")' > hello.js
$ echo '{ "main": "hello.js", "output": "sea" }' > sea-config.json
$ node --build-sea sea-config.json
$ ./sea
Hello

For the time being, backward compatibility with the postject-based SEA building process as well as the --experimental-sea-config will be maintained, until there's motivation to break it (e.g. for optimizations).

See the documentation for more details.
