Dzoukr/Dapper.FSharp

Dapper.FSharp is a multi-provider data access library for .NET that supports SQL Server, MySQL, PostgreSQL, and SQLite. It provides a modular architecture for building and executing queries, including conditional filtering, pagination, and output clause support. The system includes comprehensive test coverage and build automation to ensure reliability across all supported database engines.

The library has been completely rewritten to support multiple database providers, including SQL Server, MySQL, and SQLite, by introducing a modular architecture with separate builder, domain, and deconstructor modules for each provider. This change introduces new query-building capabilities such as conditional WHERE clauses (And/Or/If), pagination (Skip/Take), and support for internal types as records mapped to the database. The update also adds support for output clauses in insert and update operations, allowing users to retrieve generated values after execution.

The repository now includes a comprehensive build system and development infrastructure. A new \Build.fs\ script using FAKE automates the NuGet packaging and publishing workflow, supported by \BuildHelpers.fs\ and \BuildTools.fs\ for managing .NET and tooling commands. The solution file (\Dapper.FSharp.sln\) is updated to include the build project and organize solution items. Additionally, an \.editorconfig\ file enforces consistent code formatting, and a \docker-compose.yml\ file is added to spin up PostgreSQL, MySQL, and SQL Server containers for testing. These changes streamline the development, testing, and release process for the library.

(repo-wide) · high confidence

Added PostgreSQL test suite; Added test coverage for SQLite support; Expanded test coverage for SQL Server and MySQL database providers; Refactored test suite to support multiple database providers.

The project's build system has been updated to target .NET 10, with the build script (\Build.fsproj\) and dependencies (\paket.dependencies\) refactored to support modern .NET versions (6.0 through 10.0). This includes adding support for MySQL and SQLite, updating test and coverage dependencies (NUnit, Coverlet), and migrating the build tooling to use Paket for dependency management.
