Running an Express server with nodemailer and redis in a Wix site

I’d like to install a REST api that runs nodemailer and Express Node JS web application that uses redis. I’ve enabled the dev tools in Wix and installed nodemailer and redis under node_modules (see screenshot).

Where do I go from here? Any tutorials I can review?

Hello, Robert.

Check out the following links:
https://nodemailer.com/usage/
https://www.w3schools.com/nodejs/nodejs_email.asp
https://www.npmjs.com/package/redis

You can also have a look at using APIs, if you can have access to it and use either Wix Fetch or Wix HTTP Functions.

Yes but none of those links demonstrate how to upload the Node files, have redis-server running, and having for example, how to have a command for Express web server, like ‘node server/app.js’ always be running.
