How does process.stdout work?

process.stdout is a writable stream provided by Node.js that represents the standard output of the current process. When you write data to process.stdout, the data is sent to the standard output of the current process. This is typically the console or terminal where the process is running, although it can be redirected to a file or another destination using shell commands. process.stdout provides a variety of methods for writing data to the output stream. For example, you can use the write() method to write a string or buffer to the output, or the end() method to signal the end of the output and close the stream. You can also use process.stdout to control various aspects of the output, such as changing the encoding of the output using the setEncoding() method or changing the color of the output using ANSI escape codes. Overall, process.stdout provides a convenient way to write output to the console or terminal in Node.js applications, and is a core component of many command-line tools and utilities.

// Write a string to stdout
process.stdout.write("Hello, world!\n");

// Write a buffer to stdout
const buffer = Buffer.from("This is some binary data.");
process.stdout.write(buffer);

// Use ANSI escape codes to change the color of the output
process.stdout.write("\x1b[31mError: \x1b[0mSomething went wrong.\n");

In this example, process.stdout is used to write data to the console. The first example uses the write() method to write a string to the output, including a newline character to move the cursor to the next line. The second example uses the write() method again, this time passing in a buffer containing binary data. The third example uses ANSI escape codes to change the color of the output. The escape code \x1b[31m sets the text color to red, while \x1b[0m resets the color to the default. This can be used to highlight important messages or errors in console output. Note that in Node.js, console.log() can also be used to write data to the console, which automatically appends a newline character to the output. However, process.stdout provides more fine-grained control over the output stream, which can be useful in some situations.
