For developers

Block development

To develop your own block, you need three essential classes.

1. block class

class [Custom]Block : IBlock

Acts as a block model

2. blockValidator class

class [Custom]BlockValidator : AbstractValidator<[Custom]Block>

Implements rules to validate user input when editing the block.

3. blockHandler class

class [Custom]BlockHandler : BlockHandlerBase<[Custom]Block>

Acts as a controller and is responsible for loading, saving and rendering the block. Override the Load and Save methods here and, if necessary, the RenderCore, and GetRoute methods if you want to use a different story template.
