Node.js - Child Processes

How can you modify this code to handle large output without buffering issues?

const { execFile } = require('child_process');
execFile('someLargeOutputScript.sh', (error, stdout, stderr) => {
  if (error) throw error;
  console.log(stdout);
});

AIncrease buffer size option in execFile call

BUse <code>spawn</code> instead of <code>execFile</code> for streaming output

CSplit output manually after execFile finishes

DNo change needed, execFile handles large output automatically

Step-by-Step Solution

Solution:

Step 1: Understand execFile buffering limits
execFile buffers all output in memory, which can cause issues with large output.
Step 2: Use spawn for streaming output
spawn returns streams for stdout and stderr, allowing processing output as it arrives without buffering limits.
Final Answer:
Use spawn instead of execFile for streaming output -> Option B
Quick Check:
Large output needs spawn streaming [OK]

Quick Trick: Use spawn for large output streaming [OK]

Common Mistakes:

Assuming execFile can handle unlimited output
Trying to split output after buffering
Ignoring buffer size limits
