Novu Framework allows you to use Zod to define the Control and Payload schemas for your workflows.

​
Add Zod to your project

1

Install Zod Packages

npm install zod zod-to-json-schema
Novu requires the zod-to-json-schema package to generate JSON schemas from your Zod definitions.
2

Use Zod in your workflow

After installation, the Zod schemas can be used interchangeably with the controlSchema and payloadSchema options in your workflow definitions.
import { workflow } from '@novu/framework';
import { z } from 'zod';

export const testWorkflow = workflow('test-workflow', async ({ step, payload }) => {
    await step.email('send-email', async (controls) => {
        return {
            subject: controls.subject,
            body: 'Hello, World!',
        };
    },
    {
        controlSchema: z.object({
            subject: z.string().default('A test subject'),
        }),
    });
}, {
    payloadSchema: z.object({
        userName: z.string(),
    }),
});

​
Controls and Payload UI

When you define a controlSchema for a step, Novu will automatically generate a UI for the controls in the workflow editor.
  • Form Input Title - Will be derived from the key of the Zod schema. Unfortunately Zod does not support custom titles at this point.
  • Form Input Type - Will be derived from the Zod schema type, with support for string, number, boolean, and enum and array types.
  • Default Value - Will be derived from the Zod schema default value.
  • Validation - Will be derived from the Zod schema validation rules, including min, max, email, url, regex and etc…
