Download 1M+ code from https://codegive.com/ce8bda7 certainly! in node.js, a child process allows you to run separate processes for executing tasks. this is particularly useful for performing cpu-intensive operations, as it helps avoid blocking the event loop in node.js, which is single-threaded by nature. overview of child processes in node.js node.js provides a built-in module called `child_process` that allows you to spawn child processes. there are several methods in this module: 1. **spawn**: launches a new process with a given command. 2. **fork**: a special case of spawn that is used to create child processes that can communicate with the parent via ipc (inter-process communication). 3. **exec**: runs a command in a shell and buffers the output. 4. **execfile**: similar to exec, but directly executes a file without a shell. key concepts **non-blocking**: child processes run asynchronously. this means your main application can continue to handle requests while processing tasks in child processes. **ipc**: child processes can communicate with the parent process using messages via the `send()` method and `message` event. code examples let's explore each method with code examples. 1. using `spawn` 2. using `fork` `fork` is specifically designed for spawning node.js processes. 3. using `exec` this method is useful for running shell commands and getting the output. 4. using `execfile` this method is similar to `exec`, but it directly executes a file. when to use child processes when you need to perform cpu-intensive tasks (e.g., image processing, data crunching) without blocking the event loop. when you want to run separate scripts or commands in isolation. when you need to maintain a clean separation of different parts of your application. conclusion child processes in node.js are powerful tools for managing tasks that can be performed asynchronously, allowing your application to remain responsive. the choice between `spawn`, `fork`, `exec`, and `execfile` depends on t ... #NodeJS #ChildProcess #windows child process Node.js Node.js child process tutorial spawn child process Node.js exec child process Node.js fork child process Node.js child process management Node.js asynchronous child processes Node.js child process communication Node.js Node.js child process examples handling child processes Node.js child process events Node.js child process error handling Node.js performance child process Node.js child process vs worker threads Node.js Node.js child process use cases
