A quick tour

Click through a real model → generator → query flow. Everything is Dart-first.

Define a modelOpen docs

import 'package:sequelize_orm/sequelize_orm.dart';

part 'users.model.g.dart';

@Table(tableName: 'users', timestamps: false)
abstract class Users {
  @PrimaryKey()
  @AutoIncrement()
  @NotNull()
  DataType id = DataType.INTEGER;

  @Validate.IsEmail('Email is not valid')
  @NotNull()
  DataType email = DataType.STRING;

  @ColumnName('first_name')
  @Validate.Min(4)
  @NotNull()
  DataType firstName = DataType.STRING;

  static UsersModel get model => UsersModel();
}

DB shape stays explicit

- table: users
- columns: id (PK, autoincrement), email (NOT NULL, isEmail), first_name (NOT NULL, min 4)
- generated: typed helpers + query extensions

How it works

A simple flow you can explain in one minute.

1

Define

Annotate a Dart class with @Table and column annotations.

2

Generate

Run build_runner to get typed helpers + query extensions.

3

Run

Use the same API on Dart VM and dart2js.

High-intent shortcuts into the docs.

Install, connect, define your first model, query.

Models & Tables

Annotations, data types, naming, timestamps, PKs.

hasOne / hasMany / belongsTo, eager loading, options.

Typed where() operators, includes, ordering, pagination.

Dart-first (and strongly typed)

Build queries with typed columns and IDE autocomplete. Your model definitions power a safer query experience.

Annotations + code generation

Define tables with simple annotations and let build_runner generate model wrappers, helpers, and typed query extensions.

Same API on server + web

Run on Dart VM or dart2js without changing how you write models and queries.
