【nodejsシェルアプリ開発】Node.jsのSEA(Single Executable Applications)を試してみよう

            
            pkg has been deprecated with 5.8.1 as the last release.
There are a number of successful forked versions of pkg already with various feature additions.
Further, we’re excited about Node.js 21’s support for single executable applications.

Thank you for the support and contributions over the years.
The repository will remain open and archived.

            Single-executable support is tested regularly on CI only on the following platforms:

Windows
macOS
Linux (all distributions supported by Node.js except Alpine and all architectures supported by Node.js except s390x)

This is due to a lack of better tools to generate single-executables that can be used to test this feature on other platforms.
