4synopsis: Dataflow programming and declarative concurrency
5description:
6 <https://streamly.composewell.com Streamly> is a framework to build
7 reliable and scalable software systems from modular building blocks
8 using dataflow programming (streaming) and declarative concurrency.
9 Powerful stream fusion framework in streamly allows high-performance,
10 modular combinatorial programming. Key features include:
11 .
12 * Performance on par with C (<https://github.com/composewell/streaming-benchmarks Benchmarks>)
13 * Simple API, similar to standard Haskell lists (<https://github.com/composewell/streamly-examples Examples>)
14 * Declarative concurrency with automatic scaling
15 * Filesystem, fsnotify, network, and Unicode support included
16 * More functionality provided via many ecosystem packages
17 .
18 Simple, unified, and powerful abstractions:
19 .
20 * Unifies streams, arrays, folds, and parsers
21 * Unified streams and arrays obviate the need for text and bytestring
22 * Unifies Data.List, list-t, and logict with streams
23 * Supports numerous time-domain combinators
24 * Interworks with other streaming libraries
25 * Arrays interwork with bytestring
26 .
27 We recommend the better-organized module documentation on the
28 <https://streamly.composewell.com Streamly homepage>.
