Universalify simplifies the creation of universal modules that function seamlessly in both callback-based and promise-based environments. By wrapping asynchronous functions, this package generates a single function capable of handling either callbacks or returning a promise based on the presence of a callback function. This eliminates the need for maintaining separate callback and promise versions of your module, ultimately streamlining development and reducing code duplication. It's ideal for libraries aiming for broad compatibility and cleaner asynchronous handling.
Universalify, an npm package, shows sporadic release activity. It had initial releases in 2017, with a few versions published. 2020 marked a peak with versions 0.2.0, 1.0.0 and 2.0.0. After a long pause, version 2.0.1 was release in November 2023. No releases have occurred since then until August 2025.
Universalify's npm package downloads show strong growth from March 2024 to July 2025, peaking at over 443 million. A slight decline appears in August 2025, with September 2025 downloads significantly lower, likely due to incomplete monthly data. Overall, the package indicates high and increasing usage.
