from2: Readable Stream Wrapper

from2 is a convenience wrapper for Node.js `ReadableStream` (specifically, the `readable-stream` base class), designed to simplify the creation of readable streams while correctly handling backpressure. The current stable version is 2.3.0, published in 2016, indicating the project is likely abandoned or in long-term maintenance with no active development or planned release cadence. It differentiates itself by offering an API inspired by `from` and `through2`, providing `from2.obj` for object mode streams and `from2.ctor` for creating reusable stream constructors, which can improve performance for multiple similar streams. It aims to make stream creation more approachable than direct `ReadableStream` implementation.
