string-width calculates the visual width of a string, accounting for Unicode characters and grapheme clusters. It's essential for terminal-based applications or user interfaces where precise character width is needed for alignment, formatting, or truncating text to fit within a defined space. Unlike string.length, this package accurately reflects how wide a string renders on the screen, considering both single and double-width characters.
String-width's release frequency is sporadic. Initial releases occurred in 2015-2017, with periods of inactivity. 2019 saw a flurry of releases, including versions 3.1.0, 4.0.0 and 4.1.0. Activity continued in 2021 and 2022, then picked up in 2023-2024. August 2025 saw the release of version 8.0.0, after a period of no releases.
String-width npm package downloads show a generally increasing trend from February 2024 to July 2025, peaking at over 1 billion downloads. August 2025 downloads are significantly lower, but this is likely due to the month being incomplete as of today, August 27, 2025.
