fsprojects/FSharp.Data.Adaptive
FSharp.Data.Adaptive is a reactive programming library that enables efficient, incremental updates to data structures by tracking dependencies and computing deltas. It provides adaptive and changeable collections (lists, sets, maps) alongside adaptive values, allowing systems to automatically propagate changes through a dependency graph. The library supports both F# and C# interop, with additional demos illustrating file system events and web-based usage.

How it got here
2019 · Adaptive data structures and reactive primitives
The project was renamed to FSharp.Data.Adaptive and upgraded to .NET 8, while introducing a comprehensive set of adaptive and changeable data structures (lists, maps, sets) with reactive update capabilities. This period focused on building the core infrastructure for dependency tracking, callback management, and transactional updates, alongside C# interop and demo applications.

2021–2022 · Adaptive data structures and demos
This period focused on implementing and demonstrating adaptive data structures, including bags, lists, and multi-table lookups, alongside new demo applications for file system queries and trimmed publishing. The work emphasized observability and change tracking within adaptive collections.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 29 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 3d59010304 — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
