migtool 2.5.0

Migrate is a tool for performing declarative migrations by finding differences between an expected database schema and the existing one, currently in a SQLite database. It also generates type-safe F# code with CRUD operations for your database schema.

Installation

If you just want to test the tool without installing .Net, then you can use a Docker image:

podman run -it 'mcr.microsoft.com/dotnet/sdk:10.0' bash

Inside the container run:

export PATH="$PATH:/root/.dotnet/tools"

After having .Net in your system you can run

dotnet tool install --global migtool

Quickstart

mkdir test_db
cd test_db
mig init
# generated project files with example definitions
mig status
# output shows migration for existing definitions
mig commit
# generates and executes migration
mig log
# output shows migration metadata and a summary of executed steps
mig codegen
# generates type-safe F# code with CRUD operations
