Discuss Spawn() method.
Used to launch a new process and execute a command. It streams the input/output data of the child process (stdout and stderr) in real-time.
- 1
Returns: A object, with access to stdout and stderr as streams.
- 2
The result of the spawn function is a child process instance that implements EventEmitterAPI.
- 3
Suitable for handling large amounts of data because it streams results
- 4
Gives you fine-grained control over the child process's input/output.
- 5
Use it when you need to run a command, and you expect real-time output (e.g., streaming logs from a CLI tool).
- 6
The child_process.spawnSync() function provides equivalent functionality in a synchronous manner that blocks the event loop until the spawned process either exits or is terminated.
- 7
Handlers for events can be attached or registered to the child instance created.
- 8
The spawn method is used to create child processes for long-lived, I/O-intensive tasks. It's more efficient than exec for processes that need to stream data.
- 9
The child_process.spawn() method spawns the child process asynchronously, without blocking the Node.js event loop.
