Notification Workflows as Code

For API documentation and reference, please visit Echo API Reference.

client.workflow('comment-on-post', async ({step, subscriber}) => {
  const inAppResponse = await step.inApp('in-app-step', async (inputs) => {
    return {
      body: renderReactComponent(inputs)
  }, {
    inputSchema: {
      // ...JSON Schema or ZOD/Ajv/Class Validators definition

  // Novu Worker Engine will manage the state and durability of each step in isolation
  const { events } = await step.digest('1 day');

  await'email-step', async () => {
    return {
      subject: 'E-mail Subject',
      body: renderReactEmail(<ReactEmailComponent events={digestedEvents} />);
  }, {
    // Step-level inputs defined in code and controlled in the novu Cloud UI by a Non-Technical Team member
    inputSchema: {
      // ...JSON Schema
    providers: {
      sendgrid: async (inputs) => {
        // Echo runs as part of your application, so you have access to your database or resources

        return {
          to: email,
          ipPoolName: 'custom-pool'
    skip: () => {
      // Write custom skip logic
      return inAppResponse.seen || subscriber.isOnline;
// Define your workflow trigger payload using json schema and custom validation;
}, {
  payloadSchema: {
    // ...JSON Schema

Embeddable Notification Center
