AdminJS — Auto-Generated Admin Panel for Node.js Apps

Introduction

AdminJS is an open-source admin panel framework for Node.js applications. It connects to your existing database or ORM and automatically generates a full-featured admin UI with CRUD operations, filters, and bulk actions, requiring minimal configuration.

What AdminJS Does

• Auto-generates admin CRUD interfaces from database models
• Supports multiple ORMs and databases (Sequelize, TypeORM, Mongoose, Prisma, MikroORM)
• Provides role-based access control and authentication
• Offers customizable React-based UI components
• Handles file uploads, rich text editing, and relation management

Architecture Overview

AdminJS runs as an Express, Hapi, Koa, Fastify, or NestJS plugin that introspects your data models at startup. It generates a React single-page application served alongside your existing routes. Database adapters translate ORM-specific schemas into a unified resource model, and actions (list, show, edit, delete, bulk) are rendered automatically with customizable overrides.

Self-Hosting & Configuration

• Install the core package and the adapter for your ORM (e.g., @adminjs/sequelize)
• Mount AdminJS as a middleware plugin in your web framework
• Configure authentication via the built-in session-based auth or custom providers
• Override default components by providing custom React files
• Deploy alongside your existing Node.js application with no separate server needed

Key Features

• Zero-boilerplate admin UI generation from existing data models
• Six ORM adapters covering the most popular Node.js database libraries
• Custom actions and bulk operations for business-specific workflows
• Theming and component overrides using standard React
• Built-in dashboard with widgets for quick data summaries
