Resend react prop: pass the component and the Node SDK renders it, and it is Node-only

TL;DR

tsx import { Resend } from 'resend'; import { WelcomeEmail } from './emails/welcome'; const resend = new Resend(process.env.RESEND\_API\_KEY); const { data, error } = await resend.emails.send({ from: '[SENDER]', to: ['[RECIPIENT]'], subject: 'Welcome', react: WelcomeEmail({ name: '[NAME]' }), }); if (error) { console.error(error); }

import { Resend } from 'resend';
import { WelcomeEmail } from './emails/welcome';

const resend = new Resend(process.env.RESEND_API_KEY);

const { data, error } = await resend.emails.send({
  from: '[SENDER]',
  to: ['[RECIPIENT]'],
  subject: 'Welcome',
  react: WelcomeEmail({ name: '[NAME]' }),
});

if (error) {
  console.error(error);
}

Steps

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

The API reference describes react as the React component used to write the message, only available in the Node.js SDK. Verified live at https://resend.com/docs/api-reference/emails/send-email. The Next.js guide shows the react prop in use at https://resend.com/docs/send-with-nextjs.
