Why Resend need React to work in Express??

[AlejandroMora15]

I am develop an API in express with Typescript, and I am using Resend to send emails. I followed the instructions of the official doc page: https://resend.com/docs/send-with-express.

In local works perfectly. However, when I try to deploy in prod creating the build, I get this error:

node_modules/resend/dist/index.d.ts(1,24): error TS7016: Could not find a declaration file for module 'react'. '/opt/render/project/src/node_modules/react/index.js' implicitly has an 'any' type.

I cannot find any solution. Why Resend need React to work in express?

@AlejandroMora15 you don't need react to send an email with resend on an express server.

Did you use react components in the email body?

I did not need to install react for using the example
const { data, error } = await resend.emails.send({ from: "Acme <onboarding@resend.dev>", to: ["delivered@resend.dev"], subject: "hello world", html: "<strong>it works!</strong>", });

The problem is when I install Resend in my express BE, it also install React!
