ProjGraph.Lib.EntityFramework

Entity Framework Core DbContext and ModelSnapshot analysis with Mermaid ERD generation for .NET projects.

NuGet License: MIT

Installation

dotnet add package ProjGraph.Lib.EntityFramework

Overview

ProjGraph.Lib.EntityFramework parses EF Core DbContext source files and compiled ModelSnapshot migration snapshots to produce Mermaid ERD diagrams.

It supports:

  • Discovering DbContext and ModelSnapshot files in a project directory
  • Extracting entities/tables, columns/properties (with types and nullability), and foreign-key relationships
  • Both Fluent API and data annotation configuration
  • Generating Mermaid erDiagram diagrams

Usage

Register all services:

using ProjGraph.Lib.Core;
using ProjGraph.Lib.EntityFramework;

services.AddProjGraphCore();
services.AddProjGraphEntityFramework();

Generate an ERD from a DbContext file

using ProjGraph.Lib.EntityFramework.Application;
using ProjGraph.Lib.EntityFramework.Application.UseCases;

var efAnalysisService = provider.GetRequiredService<IEfAnalysisService>();

var model = await efAnalysisService.AnalyzeContextAsync("src/Data/AppDbContext.cs");

var renderer = provider.GetRequiredService<MermaidErdRenderer>();
string diagram = renderer.Render(model);

Example output:

erDiagram
    Order {
        Guid Id PK
        string CustomerName
        DateTime PlacedAt
    }
    OrderLine {
        Guid Id PK
        Guid OrderId FK
        string ProductName
        int Quantity
    }
    Order ||--o{ OrderLine : "has"

Generate an ERD from a ModelSnapshot

var analyzeSnapshot = provider.GetRequiredService<AnalyzeSnapshotUseCase>();
var model = await analyzeSnapshot.ExecuteAsync("src/Migrations/AppDbContextModelSnapshot.cs");

Discover contexts or snapshots automatically

var discoverContexts = provider.GetRequiredService<DiscoverContextsUseCase>();
IReadOnlyList<string> contextFiles = await discoverContexts.ExecuteAsync("src/");

var discoverSnapshots = provider.GetRequiredService<DiscoverSnapshotsUseCase>();
IReadOnlyList<string> snapshotFiles = await discoverSnapshots.ExecuteAsync("src/");
