How to add Content-Type headers automatically using res.render?

[Wesley de Souza]

Whenever I use res.render, I'm assuming my template render will result an HTML, but that's not the case for every routed request.

Express does not add a Content-Type header to this response, I assume because some template engine can eventually return other stuff besides HTML, but that's not the case for most of my projects using Jade.

Is there a way of configuring Express to add this header when using the res.render?

In my quest to solve this I could only find solutions that would either require me to manually add the header before every res.render (which is not optimal), or using a middleware (which is too generic or will require additional logic outside my app structure).

res.set('content-type', 'text/plain');

res.render('index', { title: 'Express' });

Not sure why you classify using a middleware as undesireable, it's the standard approach to things like this in express.
