Sequelize

@adminjs/sequelize
Before reading this article, make sure you have set up an AdminJS instance using one of the supported Plugins. Additionally, you should have installed @adminjs/sequelize as described in Getting started section.
This guide will assume you have set up Sequelize using it's documentation or Nest.js documentation.
There are small differences in how you connect Sequelize to Nest.js vs other plugins, so the guide will be split into two sections accordingly.
Example model:
category.entity.ts
import { DataTypes, Model, Optional } from 'sequelize'
import sequelize from './index'
interface ICategory {
id: number;
name: string;
createdAt: Date;
updatedAt: Date;
}
export type CategoryCreationAttributes = Optional<ICategory, 'id'>
export class Category extends Model<ICategory, CategoryCreationAttributes> {
declare id: number;
declare name: string;
declare createdAt: Date;
declare updatedAt: Date;
}
Category.init(
{
id: {
type: DataTypes.INTEGER,
autoIncrement: true,
primaryKey: true,
},
name: {
type: new DataTypes.STRING(128),
allowNull: false,
},
createdAt: {
type: DataTypes.DATE,
},
updatedAt: {
type: DataTypes.DATE,
},
},
{
sequelize,
tableName: 'categories',
modelName: 'category',
}
)
Sequelize connection:
import { Sequelize } from 'sequelize'
const sequelize = new Sequelize('postgres://adminjs:[email protected]:5435/adminjs', {
dialect: 'postgres',
})
export default sequelize

Standard

Make sure you have followed the tutorial for the framework you are using in the Plugins section.
The configuration for non-Nest.js plugins is basically the same for each one of them:
  • You must import AdminJSSequelize adapter and register it
  • You must import the entities you want to use and pass them to AdminJS resources options
app.ts
// ... other imports
import * as AdminJSSequelize from '@adminjs/sequelize'
import { Category } from './category.entity'
AdminJS.registerAdapter({
Resource: AdminJSSequelize.Resource,
Database: AdminJSSequelize.Database,
})
// ... other code
const start = async () => {
const adminOptions = {
// We pass Category to `resources`
resources: [Category],
}
// Please note that some plugins don't need you to create AdminJS instance manually,
// instead you would just pass `adminOptions` into the plugin directly,
// an example would be "@adminjs/hapi"
const admin = new AdminJS(adminOptions)
// ... other code
}
start()

Nest.js

Make sure you have set up your app.module.ts according to Nest.js documentation and you have followed Nest.js plugin tutorial as well.
Your app.module.ts should have imports option which contains:
  • SequelizeModule.forRoot({ uri: '...', dialect: '...' }) to set up Sequelize
  • AdminModule.createAdminAsync({ ... }
You should also be able to get Sequelize to work if you set it up using a Nest.js database provider. The main point is to have a database connection established before AdminJS is initialized.
In your app.module.ts add these imports at the top of the file:
app.module.ts
import * as AdminJSSequelize from '@adminjs/sequelize'
import AdminJS from 'adminjs'
Following this, register AdminJSSequelize adapter somewhere after your imports:
app.module.ts
AdminJS.registerAdapter({
Resource: AdminJSSequelize.Resource,
Database: AdminJSSequelize.Database,
})
This will allow you to pass Sequelize models for AdminJS to load. If we use the Category entity that we used as en example earlier, you should import it into app.module.ts and pass it into resources in your adminJsOptions:
app.module.ts
// ... other imports
import { Category } from './category.entity'
// ... other code
AdminModule.createAdminAsync({
useFactory: () => ({
adminJsOptions: {
rootPath: '/admin',
resources: [Category],
},
}),
}),
// ... other code
