Question 1

How do I get terminal size in a Node.js child process?

Accepted Answer

Use terminal-size to reliably retrieve dimensions even when process.stdout.columns is undefined. Import the module and call terminalSize() to get an object with columns and rows, which works in non-interactive contexts.

Question 2

What's the difference between terminal-size and process.stdout.columns?

Accepted Answer

terminal-size works in edge cases like child processes or piped output where process.stdout.columns may be undefined. It ensures cross-platform reliability, while native methods fail in non-interactive environments.

Question 3

Does terminal-size work on Windows?

Accepted Answer

Yes, the README confirms that terminal-size is tested and works on macOS, Linux, and Windows, providing consistent results across different platforms without additional setup.

Question 4

How to install terminal-size in my project?

Accepted Answer

Install via npm with 'npm install terminal-size'. Then import it in your Node.js script using ES modules or CommonJS, as shown in the usage example, for quick integration.

Question 5

Can terminal-size detect when the terminal is resized?

Accepted Answer

No, terminal-size only provides a one-time size snapshot. For real-time updates, you need to implement polling or use other libraries, as this module does not include event handling for resizes.

Question 6

terminal-size vs other npm packages like 'tty'?

Accepted Answer

terminal-size is specifically designed for reliable terminal dimension retrieval in edge cases, while Node.js's built-in 'tty' module offers broader TTY handling but may not handle non-interactive contexts as effectively.
