ra-data-simple-prisma-custom v2.1.0

React Admin + Prisma 🤝

Create a fullstack react-admin app adding just one file on the server!

Most of the examples will use Next.js but you can use any node-based server-side framework.

Installation

yarn add ra-data-simple-prisma

or

npm i ra-data-simple-prisma

or

pnpm i ra-data-simple-prisma

Frontend: import the DataProvider

import { Admin, Resource } from "react-admin";
import { dataProvider } from "ra-data-simple-prisma";

const ReactAdmin = () => {
  return (
    <Admin dataProvider={dataProvider("/api")}>
      <Resource name="users" />
    </Admin>
  );
};

export default ReactAdmin;

Backend: import the request handlers

Simplest implementation ever:

// /api/[resource].ts <= catch all resource requests

import { defaultHandler } from "ra-data-simple-prisma";
import { prismaClient } from "../prisma/client"; // <= Your prisma client instance

export default function handler(req, res) {
  defaultHandler(req, res, prismaClient);
}

With an audit log (ex. uses next-auth):

// /api/[resource].ts <= catch all resource requests

import { defaultHandler } from "ra-data-simple-prisma";
import { prismaClient } from "../prisma/client";
import { authProvider } from "../providers/authProvider";
import { getSession } from "next-auth/react";


export default function handler(req, res) {
  const session = await getSession({ req });
  defaultHandler(req, res, prismaClient, {
    audit: {
      model: prismaClient.audit_log,
      authProvider: authProvider(session)
    },
  });
}

audit:

• model: Insert your audit_log table ex. prisma.auditLog
• authProvider: Insert your AuthProvider from React-Admin
• columns?: Link your database tables {id: "id", date: "created_at"}
• enabledForAction?: Enabled for which action ex. {create: true, update: true, delete: false} enabledResources?: List of resources which are to be audited. Default all.

Overrides

All dataProvider methods can be overridden for a given resource, or all.

// /api/post.ts <= override default handler for specific resource

export default function handler(req: NextApiRequest, res: NextApiResponse) {
  switch (req.body.method) {
    case "create":
      return createHandler<Prisma.PostCreateArgs>(req, res, prismaClient.post, {
        connect: {
          tags: "id",

          tagIds: {
            tag: "id",
          },
          // or

              media: "id",

        }
      )
    case "update":
