fast-diff delivers a remarkably efficient implementation of the longest common subsequence (LCS) diff algorithm, enabling swift and accurate comparison of text strings. Optimized for speed, it excels where performance is critical, making it ideal for tasks like version control, text editors, and code comparison tools. Its focus on minimizing execution time distinguishes it from standard diff libraries, offering a substantial speed advantage, particularly when dealing with large text inputs.
The fast-diff npm package has seen sporadic releases since its initial version in October 2014. Releases occurred in June 2015, October 2016 (two versions), September 2017, October 2018 and May 2023. There have been no releases in 2024 or 2025, and long periods of inactivity between releases are normal..
Fast-diff npm package downloads show a generally upward trend from February 2024 to July 2025, peaking at over 103 million in June 2025. August 2025 downloads are significantly lower, but the month is not yet complete. Overall growth and high download numbers indicate a popular package.
