Mastering Node.js child_process: exec vs spawn and Multi‑Core Strategies
Node.js’s child_process core module enables creation of child processes to leverage multi‑core CPUs and inter‑process communication, while also allowing execution of external files or system commands; this article explores the differences and inner workings of its exec and spawn methods.
child_processis a very important core module in Node.js. Through it you can create child processes to utilize multi‑core CPU resources and implement communication between the main process and child processes; when the child process finishes, the main process obtains its result.
In addition, child_process can also invoke external files or system commands, expanding the possibilities of business logic.
The child_process methods exec and spawn differ in certain ways, and their internal implementations are examined in the original article by Safia Abdalla.
