Import from existing databases

Creating a Sequelize schema from existing databases can be done thanks to the integration with Luna Modeler. The following workflow explains how to load existing databases and create a Sequelize project.

  1. Load existing database structure to Luna Modeler
  2. In Luna Modeler copy selected tables
  3. Run Meteor Modeler and create a new empty project
  4. Paste the selected object to your Sequelize project
  5. Objects will be converted to Sequelize automatically

Frequently Asked Questions
What is a Sequelize schema design tool?

A Sequelize schema design tool is software that lets you visually design and document Sequelize ORM models, associations, and field definitions without writing boilerplate code manually. Meteor Modeler lets you draw Sequelize model diagrams, define BelongsTo, HasOne, HasMany, and BelongsToMany associations graphically, and then automatically generate the corresponding Sequelize ORM scripts ready to use in your Node.js project.

Which Sequelize associations does Meteor Modeler support?

Meteor Modeler supports all four core Sequelize association types: BelongsTo, HasOne, HasMany, and BelongsToMany. You draw associations visually between models on the diagram canvas, and Meteor Modeler generates the correct Sequelize association code including join tables for many-to-many relationships.

Is there a free version of Meteor Modeler?

Yes. Meteor Modeler includes a freeware version for smaller projects with no time limit. For larger projects, a paid Basic Edition is available as a one-time purchase. There is also a 14-day free trial of the full edition, with no credit card or account required to download.

How does Meteor Modeler integrate with Luna Modeler?

Meteor Modeler integrates with Luna Modeler via copy-and-paste. Open an existing relational database in Luna Modeler, copy the tables you want, then paste them into a new Meteor Modeler project. The objects are automatically converted to Sequelize models — fields, data types, and relationships are mapped across — so you can generate Sequelize code from an existing SQL database schema without manual rewriting.

What scripts can Meteor Modeler generate?

Meteor Modeler generates Sequelize ORM scripts (model definitions with fields, data types, validations, and options) and Sequelize Module scripts (which include the association code linking models together). You can generate scripts for a single selected model or for the entire project at once. Custom templates are also supported, letting you generate any text-based output — code snippets, CSV files, UI components — from your Sequelize model definitions.
