PostgreSQL, MySQL, and SQLite3 storage for BackboneORM.

BackboneSQL provides an interface for BackboneORM models to persist to SQL databases.

Please checkout the website for examples, documentation, and community!

Schema definition

Fields are specified in the models schema property. Each (non-relation) field corresponds to a database column.

Each field must have a type and may be provided with the additional options.

An auto-incrementing field named id is automatically created as the primary key for each model.

To supply options the field descriptor is passed as an array, with the first item being the field type and a settings object as the second.

Available types

All types supported by Knex are available. Add column specific options along with the settings object for the field. The first letter of the type name is optionally capitalized, while the remainder must be camelCase.

Common field options

These options may be applied to any field. Note that column options are currently only applied when the columns are created.

• nullable: Defaults to true. Set to false to throw an error on null values.
• indexed: Defaults to false. Set to true to create an index on the column.
• unique: Defaults to false. Set to true to create a unique constraint on the column.

CoffeeScript schema example

SQLSync = require('backbone-sql').sync

class Project extends Backbone.Model

  # Database connection and table name are specified with the urlRoot
  urlRoot: 'postgres://username:password@localhost:27017/my_database/projects'

  # Schema defines the fields for the model's table
  schema:
    created_at: 'DateTime'
    type: ['Integer', nullable: false]
    name: ['String', unique: true, indexed: true]

  # Kick it off by setting the model's sync to an SQLSync
  sync: SQLSync(Project)

JavaScript schema example

var SQLSync = require('backbone-sql').sync;

var Project = Backbone.Model.extend({

  // Database connection and table name are specified with the urlRoot
  urlRoot: 'postgres://username:password@localhost:27017/projects',

  // Schema defines the fields for the model's table
  schema: {
    created_at: 'DateTime',
    type: ['Integer', {nullable: false}],
    name: ['String', {unique: true, indexed: true}]
  }
});

// Kick it off by setting the model's sync to an SQLSync
Project.prototype.sync = SQLSync(Project);
