This is a guide intended at users of yarn modern. For those who are using yarn classic (1.x), you can do something similar to the pnpm guide.

​
1. Create transactional workspace

Create a new folder called transactional inside of where you keep workspace packages (generally ./packages/*). Include a new package.json and do not forget to add this to the workspaces of your monorepo’s package.json.

​
2. Set linker either to node-modules or to pnpm

Currently, React Email can only work with yarn’s node-modules and pnpm install modes so you will need to set it to one of these two on your .yarnrc.yml file:
.yarnrc.yml
nodeLinker: node-modules

​
3. Install dependencies

Install React Email in the transactional workspace.
packages/transactional
yarn add react-email -D -E
yarn add @react-email/components react react-dom -E

​
4. Add scripts

Include the following script in your package.json file.
packages/transactional/package.json
{
  // ...
  "scripts": {
    "dev": "email dev"
  }
  // ...
}

​
5. Write your emails

Create a new folder called emails, create a file inside called MyEmail.tsx and add the following example code:
packages/transactional/emails/MyEmail.tsx
import { Button, Html } from "@react-email/components";
import * as React from "react";

export const MyEmail = () => {
  return (
    <Html>
      <Button
        href="https://example.com"
        style={{ background: "#000", color: "#fff", padding: "12px 20px" }}
      >
        Click me
      </Button>
    </Html>
  );
}

export default MyEmail;

​
6. Run preview server

Start the email previews development server:
packages/transactional
yarn dev

​
7. See changes live

Visit localhost:3000 and edit the emails/MyEmail.tsx file to see the changes.
