0.2.2

Added the notifyChildrenChanged() method to the StepEditorContext interface.

0.2.1

Support undo and redo. This feature is disabled by default. To enable it add the below config.

const config = {
  undoStackSize: 10,
  // ...
};

0.2.0

Editor's Context

We've changed an approach how the editors should notify the designer about changes in the definition. We've deleted revalidate() and notifiyDefinitionChanged() methods from the Designer class. Instead of this, now editors receive an editor's context.

interface StepEditorContext {
  notifyNameChanged(): void;
  notifyPropertiesChanged(): void;
}

interface GlobalEditorContext {
  notifyPropertiesChanged(): void;
}

const config = {
  // ...
  editors: {
    stepEditorProvider: (step: Step, context: StepEditorContext) => {
      // ...
      context.notifyPropertiesChanged();
      // ...
    },
    globalEditorProvider: (definition: Definition, context: GlobalEditorContext) => {
      // ...
      context.notifyPropertiesChanged();
      // ...
    }
  }
};

Type Requirments

The type of a step cannot contain special characters from now. Check the type validator.

• ✅ someType
• ✅ some-type
• ✅ some_type
• ❌ some type
• ❌ someType!

By this, we could add the type to an element's class on the SVG canvas. That allows to customize components by CSS. Check this example.

Restrictions

We added canInsertStep, canMoveStep and canDeleteStep callbacks to the StepsConfiguration. You may restrict some activity in the designer by this.

const config = {
  // ...
  steps: {
    canInsertStep: (step, targetSequence, targetIndex) => {
      return targetSequence.length < 5;
    },
    canMoveStep: (sourceSequence, step, targetSequence, targetIndex) => {
      return !step.properties['isLocked'];
    },
    canDeleteStep: (step, parentSequence) => {
      return step.name !== 'x';
    }
    // ...
  }
};
