Can't you just use this? It will auto set the content type to application/json
return response()->json($cached_data);

How to set content-type from API routes
I am storing data as json in Redis. When I get a cache hit, I am retrieving this json-formatted data from Redis and then decoding it before returning.
That seems like a silly step since it just get re-encoded before sending the response. So I simply returned the json straight from Redis. It saves a good 20 to 30 ms. However it is sending the data as text/html and not application/json.
When I tried setting the content type as so:
return response($cached_data)
->header('Content-Type', 'application/json');
... it simply sends the header as a part of the text/html and not a header.
Any idea how to properly set the content type from the api route file?

That sets the content type to application/json but wraps the data in quotes and essentially makes the client code think it's just a string.

@rguttersohn You can decode/parse the JSON on the client side to convert it back to its original format.

@gych Totally but that is an unnecessary decoding/encoding step. I fully recognize that 20 to 30ms is nothing in the grand scheme of things, but it would be nice to just already-encoded json as is. But I am thinking this may only be possible from routes/web.php.

@rguttersohn So why are you spending so much time and effort into “solving” this? Surely there are bigger problems in your app?

@martinbean Not a helpful response. I never said I was spending 'so much time' on this. I am hoping to remove a redundant step from my response that was unnecessarily adding time.
