Blocks

Integrations can create custom blocks for documents. Blocks are small unit of content in a page document (like a paragraph, table, embed, etc.).
Define a custom block
Custom blocks are defined in the integration's manifest file:
blocks:
  - id: helloworld
    title: Hello World
All blocks defined in an installed integrations will be listed in the insertion palette for all editors of the space.
Execution flow for a block
Rendering of custom blocks is controlled in the integration's code and executed in the GitBook backend.

    actor User
    User ->>+ GitBook: Insert block in the editor
    loop Every interaction with the block
        GitBook ->>+ Integration: Execute rendering of the block with current props & state
        Integration ->>- GitBook: Return ContentKit output for the block
        GitBook ->>- User: Render UI in the editor
        User -->+ GitBook: Interact with the block, updating the state or props
    end
Render a basic block
Block are being rendered in the ContentKit format.
import { createComponent, createIntegration } from '@gitbook/runtime';
​
const helloWorld = createComponent({
  componentId: 'helloworld',
  async render() {
    return (
      <block>
        <box>
          <text>Hello world</text>
        </box>
      </block>
    );

});
