# Dommel
CRUD operations with Dapper made simple.

| Build | NuGet |
| ----- | ----- |
| [![CI](https://github.com/henkmollema/Dommel/actions/workflows/ci.yml/badge.svg)](https://github.com/henkmollema/Dommel/actions/workflows/ci.yml) | [![NuGet](https://img.shields.io/nuget/vpre/Dommel.svg?style=flat-square)](https://www.nuget.org/packages/Dommel) |

<hr>

Dommel provides a convenient API for CRUD operations using extension methods on the `IDbConnection` interface. The SQL queries are generated based on your POCO entities. Dommel also supports LINQ expressions which are being translated to SQL expressions. [Dapper](https://github.com/StackExchange/Dapper) is used for query execution and object mapping.

There are several extensibility points available to change the behavior of resolving table names, column names, the key property and POCO properties. See [Extensibility](https://www.learndapper.com/extensions/dommel#extensibility) for more details.
