UglifyJS is a JavaScript parser, minifier, compressor, and beautifier toolkit. It's essential for optimizing web performance by reducing file sizes, making JavaScript code smaller and faster to download. UglifyJS removes unnecessary characters and comments, shortens variable names, and applies other techniques to minimize code footprint. This results in improved website loading times and a better user experience. It's widely used in build automation processes and deployment pipelines.
UglifyJS releases were infrequent. There was one release in March 2015 (version 2.4.10) and another in May 2017 (version 2.4.11). Since then, there have been no releases for over 8 years, as of August 2025. The package appears to be unmaintained.
UglifyJS downloads fluctuated significantly from February 2024 to August 2025. A peak occurred in November 2024 (76,023 downloads). Download numbers stabilized around 40,000 in early 2025, with a notable increase in June and July, before decreasing in August (incomplete data).
