configuration file for dev settings

[LeoTuet]

After seeing a lot of issues relating to dev server configuration like #248 and #372, I think it makes sense to introduce a config file like react-email.config.js (similar to next having next.config.js or vite with vite.config.ts) on top of commandline args. This file could then also be typed which makes configuration more intuitive.

I would also be happy to implement it :)

Can you share more on this and how this would work. I had some early thoughts on this when creating react-email but still wasn't 100% sure.

react-email would expose a function called e.g configureReactEmail which has a typed object as a param and just return the object again.

Then you would import and default export this function into your react-email.config.js

import { configureReactEmail } from "react-email"

export default configureReactEmail({
	srcDir: "src"
})

(Its the same as just having export default {} in react-email.config.js. The function is just purely there to enable type hinting)

Then it is possible to create a function/variable which just imports the default export of react-email.config.js

const config = (await import(`${projectRoot}/react-email.config.js`)).default

I'd love for us to stay away from this as much as we can:
