@erdflow/prisma

Interactive ERD from a Prisma schema — local-first, opens in your browser.

Part of the erdFlow family. Other domains (Laravel, …) ship as separate packages later.

What it does

1. Detects your Prisma schema (prisma/schema.prisma, multi-file folder, or prisma.config.ts)
2. Parses models, relations, enums, and indexes
3. Starts a local server at http://127.0.0.1:4317
4. Opens an interactive entity-relationship diagram

Example output:

✓ Detected Prisma
✓ prisma/schema.prisma
✓ 12 entities · 2 enums · 11 relations · 3 indexes
→ http://127.0.0.1:4317/

Watching schema files for changes...

Quick start

From the project (or monorepo package) that owns the Prisma schema:

npx @erdflow/prisma

Or install globally:

npm install -g @erdflow/prisma
erdflow-prisma

Explicit path

npx @erdflow/prisma --prisma ./prisma/schema.prisma
npx @erdflow/prisma --prisma ./prisma/schema
npx @erdflow/prisma --prisma ./backend/prisma/schema.prisma

Supports Prisma v6 and v7 (url-less datasource, multi-file, prisma.config.ts).

Providers: PostgreSQL, MySQL, SQLite, MongoDB (Document View instead of SQL View), and other Prisma SQL providers.

Options

| Flag | Description | | --- | --- | | --prisma <path> | Schema file or multi-file folder | | --port <number> | Server port (default 4317) | | --no-open | Do not open the browser | | --no-watch | Disable live re-parse |

npx @erdflow/prisma --prisma ./prisma/schema.prisma --port 5000
npx @erdflow/prisma --prisma ./prisma/schema.prisma --no-open

Live updates

With watch enabled (default), editing .prisma files re-parses and updates the browser over WebSocket.
