Introduction

Learn how to send notifications with Remix, React email and Novu. You can check out the complete code for a working app.

​
Prerequisites

  • A Novu account
  • Node installed on your machine
  • A working Remix app

​
Follow these Steps

​
1. Install all dependencies including react email components

  npm install @novu/framework @react-email/components react-email

​
2. Integrate Novu with Remix

Within the app/routes directory, create an api.novu.tsx file. 
// app/routes/api.novu.tsx

import { serve } from "@novu/framework/remix";
import { client, signUpWorkflow } from "~/novu/workflows";

const handler = serve({
    client: client,
    workflows: [signUpWorkflow]
  });
  
export { handler as action, handler as loader };

​
3. Create an email template in your Remix app

Within the app directory, create an emails folder and add an email template file to it. In this scenario, create a vercel-invite-user.tsx file and the code below to it: 
// app/emails/vercel-invite-user.tsx

import {
    Body,
    Button,
    Container,
    Column,
    Head,
    Heading,
    Hr,
    Html,
    Img,
    Link,
    render,
    Row,
    Section,
    Text,
    Tailwind,
  } from "@react-email/components";
  
  interface VercelInviteUserEmailProps {
    username?: string;
    userImage?: string;
    invitedByUsername?: string;
    invitedByEmail?: string;
    teamName?: string;
    teamImage?: string;
    inviteLink?: string;
    inviteFromIp?: string;
    showJoinButton?: boolean;
    inviteFromLocation?: string;
    buttonText?: string
  }
  
  const baseUrl = process.env.VERCEL_URL
    ? `https://${process.env.VERCEL_URL}`
    : "";
  
  export const VercelInviteUserEmail = ({
    username,
    userImage,
    invitedByUsername,
    invitedByEmail,
    teamName,
    teamImage,
    inviteLink,
    inviteFromIp,
    inviteFromLocation,
    showJoinButton,
    buttonText
  }: VercelInviteUserEmailProps) => {
  
    return (
      <Html>
        <Head />
        <Tailwind>
          <Body className="bg-white my-auto mx-auto font-sans px-2">

  } as VercelInviteUserEmailProps;
  
  export default VercelInviteUserEmail;
  
  export function renderEmail(input: any, payload: any) {
    return render(<VercelInviteUserEmail {...input}{...payload} />);
  }

​
4. Create a Novu Workflow

Next, create a Novu workflow with an email step. This code-first notification workflow approach makes it easy for product teams to modify notification content. Within the app directory, create an novu folder and add a workflows.ts file to it. Copy/paste the code below to the recently created file. 
// app/novu/workflows.ts

import { Client, workflow } from '@novu/framework';
import { renderEmail } from '~/emails/vercel-invite-user';

export const client = new Client({

  apiKey: process.env.NOVU_API_KEY,
  /**
   * Disable this flag only during local development
   * For production this should be true
   */
  strictAuthentication: process.env.NODE_ENV !== "development"
});

export const signUpWorkflow = workflow('new-signup', async ({ step, payload }) => {
  // Send a welcome email
  await step.email('send-email', async (inputs) => {
    return {
      subject: `Welcome to sending emails with Novu & Remix`,
      body: renderEmail(inputs, payload),
    };
  }, {
    inputSchema: {
      type: "object",
      properties: {
        showJoinButton: { type: "boolean", default: true },
        buttonText: { type: "string", default: "Join the team" },
        userImage: {
          type: "string",
          default: "https://react-email-demo-bdj5iju9r-resend.vercel.app/static/vercel-user.png",
          format: "uri",
        },
        invitedByUsername: { type: "string", default: "Alan" },
        invitedByEmail: {
          type: "string",
          default: "alan.turing@example.com",
          format: "email",
        },
        teamName: { type: "string", default: "Team Awesome" },
        teamImage: {
          type: "string",
          default: "https://react-email-demo-bdj5iju9r-resend.vercel.app/static/vercel-team.png",
          format: "uri",
        },
        inviteLink: {
          type: "string",
          default: "https://vercel.com/teams/invite/foo",
          format: "uri",
        },
        inviteFromIp: { type: "string", default: "204.13.186.218" },
        inviteFromLocation: {
          type: "string",
          default: "São Paulo, Brazil",
        },
      },
    },
  });
  // JSON Schema for validation and type-safety. Zod, and others coming soon.
}, { payloadSchema: { properties: { text: { type: 'string' } } } });

5. Preview Email Workflow & Sync to Novu Cloud

Open Novu Dev Studio to preview and make changes to the email workflow as needed via the command below: 
npx novu-labs@latest echo
  1. Run the Studio

Novu Dev Studio on the first run

Note: Use the port on which your Remix app is running for the Bridge endpoint so that the Novu Dev Studio can connect to your API route as highlighted in the image above.
  1. Check out the signup email workflow and test

Preview Email workflow with Step Inputs & Payload

  1. Deploy to Novu Cloud when you’re done.
On the top right(as seen in the image above) of the Novu Dev Studio, you can sync to Novu Cloud when you’re done working locally. Note: You’ll need to create a local tunnel that the Novu Cloud environment can reach for local experimentation purposes. Ngrok is a good tunnel.

​
6. Send a Notification

Trigger a notification using the recently deployed workflow either via your Novu Cloud dashboard or code. 
import { Novu } from "@novu/node";

const novu = new Novu("<API_KEY>");

novu.trigger("new-signup", {
  to: {
    subscriberId: "789",
  }
});
Once you’ve built the workflow, you might want read one of our other guides on how to empower product teams to manage notification workflows.
