String Visual Width Calculator

This workflow provides a robust solution for determining the exact column width required to display any string in a terminal or console environment. It processes input strings by stripping ANSI escape codes, detecting full-width characters (common in CJK languages), accounting for emojis, and calculating the precise visual footprint. Ideal for CLI tools, command-line interfaces, and scripts needing perfect text alignment.

Key benefits include preventing layout breakage in formatted outputs like tables, progress bars, or logs, especially with international text or styled content. It saves development time by encapsulating complex Unicode handling into a simple function call, ensuring cross-platform consistency on Node.js >=8.

Use cases span automation scripts in n8n Code nodes for dynamic console reporting, IoT dashboard formatting where device logs include diverse characters, or Industrial IoT monitoring tools displaying multilingual status messages. Integrate via npm in custom nodes for enhanced text processing in workflows.
