OPUS
Open source knowledge base application for Teams
...The idea behind Opus (in this JS-utility ecosystem) is to provide functionality that feels native and idiomatic, helping developers quickly get things done without boilerplate. Because the library is lightweight and relies on minimal external dependencies, it is appropriate for small scripts, front-end utilities, and situations where you want to avoid over-engineering. Its simplicity also makes it easy to inspect, understand, and extend — useful traits if you prefer transparent code rather than black-box libraries.
