Generates Backbone models with typed subclasses for using Backbone.js with TypeScript and its type system.

Getting Started

models are declared as YAML, such as

  content: string[]
  done: optional bool
  person: A

  name: readonly string

and generates code in the form of

class _Model extends Backbone.Model {
  get_member() : member_type { return this.get('member'); }
  set_member(val : member_type) : void { this.set('member', val); }
  fromJSON(json) : { ... }
  • members declared optional do not raise an exception if missing from a json loaded in fromJSON.

  • members declared readonly do not have set_member generated.

the type for each member is a typescript type and must not contain spaces

Do not use the _Model classes directly! Instead, you must subclass them. For a minimal model, this typically means

class Model extends _Model {}

but usually you'll want to add methods.

Grunt plugin

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-backbone-typescript-accessor-generator --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


The "backbone_typescript_accessor_generator" task


In your project's Gruntfile, add a section named backbone_typescript_accessor_generator to the data object passed into grunt.initConfig().

  backbone_typescript_accessor_generator: {
    options: {
      // Task-specific options go here.
    your_target: {
      // Target-specific file lists and/or options go here.

Usage Examples

backbone_typescript_accessor_generator: {
  dynamic_mappings: {
    files: [
        expand: true,
        cwd: 'ts/',
        src: '*.models.yml',
        dest: 'ts/',
        ext: '-models.ts'
