execa

Execa is a modern alternative to child_process for executing external binaries. It provides a more user-friendly API and better defaults. Unlike exec-buffer, execa does not specifically focus on buffering binary data but is more general-purpose for executing commands.

child_process

The child_process module is a core Node.js module that provides the ability to spawn child processes. It is more low-level compared to exec-buffer and requires more boilerplate code to handle buffers and streams.

buffer

The buffer module is a core Node.js module that provides a way to handle binary data directly. While it does not execute binaries, it is often used in conjunction with other modules like child_process to manage binary data streams.
