fable-compiler/fable-promise

This system is an F\# library that provides interoperability with JavaScript asynchronous patterns, specifically focusing on Promise handling and AsyncIterable support. It enables F\# code to interact with JavaScript's for-await...of semantics and simplifies error handling through Result type conversions. The project has recently modernized its infrastructure by migrating to .NET 10 and Fable 5, replacing legacy build tools with EasyBuild and updating its test suite to Scriptorium.

Users can now iterate over JavaScript async iterables using the new AsyncIterable module, which provides create, createCancellable, and iter functions to bridge F\# code with JS for-await...of semantics. Additionally, the Promise module now includes a SettledValue.toResult helper to easily convert Promise.allSettled results into F\# Result types for simpler error handling.

The custom F\# build tooling in the \tools\ directory, specifically \Main.fs\ and \ShellJs.fs\, has been removed. This eliminates the local Fable-based wrapper around the \shelljs\ Node.js library, indicating a shift away from using these specific F\#-based shell utilities for build or publishing tasks.

The build system has been replaced with an EasyBuild project, introducing a new CLI interface for managing development workflows. Users can now run tests with the 'test' command (supporting a watch mode) and publish NuGet packages via the 'release' command. Additionally, Husky is now integrated to automatically install Git hooks and enforce commit message linting and code formatting on pre-commit.

The core Promise library has been significantly refactored to improve usability and clarity. The public API now includes explicit XML documentation and examples for key functions such as create, sleep, lift, reject, bind, map, and iter. The type signatures have been standardized (e.g., using 'T1/'T2 for generic parameters in bind and map) to enhance type inference and readability. Additionally, the internal implementation has been cleaned up, removing unused imports and private helper functions, resulting in a more maintainable and user-friendly interface for handling asynchronous operations.

Fable.Promise · high confidence

The project has migrated its build infrastructure from npm-based scripts to a .NET-centric workflow using EasyBuild and Fable 5. This change introduces a new .NET SDK 10 requirement (global.json), replaces the legacy FSharpLint configuration with Fantomas for code formatting, and updates the build scripts (build.sh/build.bat) to invoke the new EasyBuild project. Additionally, the repository now includes an .editorconfig for consistent F\# formatting, a new Nacara-based documentation configuration, and updated .gitignore rules to exclude Fable output artifacts and the new deploy folder.

The test suite has been ported from a custom setup to the Scriptorium testing framework, replacing previous assertion helpers with Scriptorium's \Nib.Assertion\ and \Quill.Test\ modules. This change also introduces new tests for \AsyncIterable\ support, verifying iteration, cancellation, error handling, and cleanup behaviors, alongside updated tests for Promise/Thenable interoperability.

tests · high confidence

The project has been upgraded to target .NET 10 (previously .NET Standard 2.0) and Fable.Core 5.2.0 (previously 2.0.2). The build system has been replaced with EasyBuild, introducing new dependencies like Spectre.Console.Cli and SimpleExec, while the test suite has migrated from Mocha to Scriptorium. Additionally, the source library now includes AsyncIterable support and utilizes the Fable.Package.SDK for packaging.
