In this guide, we will add a Novu Bridge Endpoint to a AWS Lambda application and send our first test workflow.

1

Run the Local Studio

The Local Studio is where you will build your notification workflows and craft the controls that will be exposed for your non-technical peers to maintain after your workflow is pushed to your Development or Production environments.

npx novu@latest dev

The dev command is your go-to command whenever you want to build and preview your changes before syncing to cloud. By default, it will start a secure tunnel that our durable cloud workflow engine will be able to communicate with, and the Local Studio web service listening on http://localhost:2022

2

Install Packages

npm install @novu/framework zod zod-to-json-schema

This will install the following packages

  • @novu/framework SDK Package
  • Zod (Recommended) - For end-to-end type safety for your Payload and Step Controls
3

Add a Novu API Endpoint

import { serve } from "@novu/framework/lambda";
import { workflow } from "@novu/framework";
import { testWorkflow } from "../novu/workflows";

module.exports.novu = serve({
    workflows: [testWorkflow],
});
4

Add a Novu Secret Key Environment Variable

Add NOVU_SECRET_KEY environment variable to your .env

NOVU_SECRET_KEY=<NOVU_SECRET_KEY>
5

Create your workflow definition

Add a novu folder in your app folder as such novu/workflows.ts that will contain 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: 'This is your first Novu Email ' + payload.userName,
        };
    },
    {
        controlSchema: z.object({
            subject: z.string().default('A Successful Test on Novu from {{userName}}'),
        }),
    });
}, {
    payloadSchema: z.object({
        userName: z.string().default('John Doe'),
    }),
});
6

Start your application

Start your AWS Lambda server with the Novu Endpoint configured.

If your Local Lambda application is running on other than 4000 port, restart the npx novu dev command with the port:

npx novu@latest dev --port <YOUR_AWS LAMBDA_PORT>
7

Test your workflow

After your application is up and running, visit the Local Studio interface that was started on http://localhost:2022 by running the npx novu dev command on the first step.

The onboarding guide will guide you to send the newly created sample workflow to your e-mail address.

8

Deploy your application

Once you have finished refining your first workflow, it’s time to sync your local changes to Novu Cloud. Novu recommends deploying your workflows similarly to how you will deploy the features that generate those notifications using your CI/CD pipeline or our CLI command.
