json2jsii

Generates jsii-compatible structs from JSON schemas

Usage

const g = new TypeGenerator({
  definitions: {
    Name: {
      description: 'Represents a name of a person',
      required: [ 'firstName', 'lastName' ],
      properties: {
        firstName: {
          type: 'string',
          description: 'The first name of the person',
        },
        lastName: {
          type: 'string',
          description: 'The last name of the person',
        },
      },
    },
  },
});

g.addType('Person', {
  required: [ 'name' ],
  properties: {
    name: {
      description: 'The person\'s name',
      $ref: '#/definitions/Name',
    },
    color: {
      description: 'Favorite color. Default is green',
      enum: [ 'red', 'green', 'blue', 'yellow' ],
    },
  },
});

fs.writeFileSync('gen/ts/person.ts', await g.render());

Then, gen/ts/person.ts will look like this;

/**
 * @schema Person
 */
export interface Person {
  /**
   * The person's name
   *
   * @schema Person#name
   */
  readonly name: Name;

  /**
   * Favorite color. Default is green
   *
   * @default green
   * @schema Person#color
   */
  readonly color?: any;
}

/**
 * Represents a name of a person
 *
 * @schema Name
 */
export interface Name {
  /**
   * The first name of the person
   *
   * @schema Name#firstName
   */
  readonly firstName: string;

  /**
   * The last name of the person
   *
   * @schema Name#lastName
   */
  readonly lastName: string;
}

Language bindings

Once you generate jsii-compatible TypeScript source (such as person.ts above), you can use jsii-srcmak in order to produce source code in any of the jsii supported languages.

The following command will produce Python sources for the Person types:

$ jsii-srcmak gen/ts \
  --python-outdir gen/py --python-module-name person \
  --java-outdir gen/java --java-package person

See the jsii-srcmak for library usage.
