PeregrineDb - Lightweight CRUD Extensions for Dapper.Net

Image of a Peregrine, from the RSPB

PeregrineDb is a small and fast Dapper.Net extension library to perform CRUD statement with POCO models.

Build status

Project aims

  1. Provide fast and lightweight CRUD extensions for Dapper
  2. Should be able to run against multiple different databases in the same project
  3. Thread safety should be guarenteed

I was using the fantastic Dapper.SimpleCRUD library and found it incredibly easy to use. However, two things drove me to write this library - I have a project which uses SqlServer and Postgres databases side-by-side, and unfortunately Dapper.SimpleCRUD does not support this. Second, I found it was missing a few crucial optimizations which was doubling the time taken to easily insert many rows.

DBMS Support

Currently, the following DBMS are supported. More will be added (e.g. SQLite) when there is demand for them:

  • Microsoft SqlServer 2012 and above
  • PostgreSQL

Features

Don't forget, for practical examples of usage, you can also browse our extensive unit tests suite.

Comparison
