You can now use Zod Schemas for defining your payload and step controls schemas. The Framework SDK will infer those zod schemas and provide a run-time validation and autocompletion for usage.

Here is an example of a Zod-based validation:

import { workflow } from '@novu/framework';
import { z } from 'zod';

workflow('comment-workflow', async ({ step }) => {
  await step.email('digest-email', async (controls) => ({
    subject: controls.subject,
    body: 'body'
  }), {
    controlSchema: z.object({
      subject: z.string().default('Hi {{subscriber.firstName}}'),
      openAiModel: z.enum(['gpt-3.5-turbo', 'gpt-4o']).default('gpt-4o'),
      aiPrompt: z.string().default('Produce a concise comment digest'),
    })
  });
}, { 
  payloadSchema: z.object({
    name: z.string(),
    comment: z.string() 
  }) 
});

Common usecases

• Validate trigger payload contents to make sure that null or undefined data ends up in your notifications.

• Provide default values for non-required attributes

• Create custom validation logic based on backend logic

• Define UI step controls and expose UI elements from zod schemas
