@picadeck/prisma-parser

Prisma schema parser for Picadeck Schema Visualizer. Reads .prisma schema files and converts them into UniversalSchema for interactive visualization.

Installation

npm install @picadeck/prisma-parser @picadeck/core

No peer dependency on Prisma is required -- this package reads .prisma files directly using @mrleebo/prisma-ast.

Usage

import express from "express";
import { schemaVisualizer } from "@picadeck/core";
import { parsePrismaFile } from "@picadeck/prisma-parser";

const app = express();

app.use(
  "/schema",
  schemaVisualizer({
    parser: () => parsePrismaFile("./prisma/schema.prisma"),
    models: [],
    theme: "dark",
  })
);

app.listen(3000);

API

parsePrismaFile(filePath)

Reads a .prisma file from disk and parses it into a UniversalSchema.

import { parsePrismaFile } from "@picadeck/prisma-parser";

const schema = await parsePrismaFile("./prisma/schema.prisma");

parsePrismaSchema(schemaContent)

Parses a Prisma schema string directly (useful when the content is already in memory).

import { parsePrismaSchema } from "@picadeck/prisma-parser";

const content = fs.readFileSync("./prisma/schema.prisma", "utf-8");
const schema = parsePrismaSchema(content);

Framework Agnostic

Prisma uses a .prisma DSL file regardless of your backend framework. This parser works the same whether you use Express, NestJS, Fastify, or any other Node.js framework.
