Ligeann an modúl child_process do Node clár eile/orduithe eile (orduithe blaoisce, scripteanna, binaries eile) a rith mar phróiseas OS ar leith. Úsáideach chun uirlisí córais a ghlaoigh, obair dhomhain-CPU a rith lasmuigh den phríomhphróiseas, nó clár eile a eagrú.
Na ceithre phríomhdhóigh
exec → run a shell command, buffer all output (simple, small output)
execFile → run a file directly (no shell — safer, faster)
spawn → stream output (for large output / long-running processes)
fork → spawn a new NODE process with an IPC channel (Node-to-Node)
