@ejferg @SteveALee Hi thanks for reporting the issue.. I'll have a look quite soon ;)
PS: Feel free to make a PR
from azure-function-express.
Thanks for the fix. I spent quite a bit of time with the Express code and didn't spot x-powered-by
could be disabled. The reason that header is send is not so explicit in the code and I'm not an express user.
I think I used express 2.x as your example had and I wasn't sure if newer version might have broken you mocking of the HTTP objects. I will certainly try it sometime.
I totally agree it's a great approach for an API serving JSON payloads. I wanted a solution for that and serving my static objects (index.html etc). Seems in that case I got a bit carried away :)
I might revisit it sometime. It seemed to me that Functions only support strings for buffers (ie in memory copies) rather than streaming from files. That's fine for dev but not for production.
Thanks again for getting back to me.

Has anybody found a work around?

@ejferg To be honest, after quite a bit of time looking at options, including connect rather than express, I decide this was not a good approach for several reasons.
- Many middleware keep state so do not make any sense in a Function and not in a server main loop.
- Even for static hosting, compared to other servers content will not be streamed so performance is poor
- Many features a server would manage are handled out side our function by Azure App Service, so this make little sense - eg CORS.
So while using Express and middleware seems like a neat idea in reality I don't think it makes much sense.
Here's a post I did on static serving in Azure
from azure-function-express.
@SteveALee Thank you so much for reporting this issue 😄
It's now fixed in v1.2.0
I didn't notice the error because I'm disabling x-powered-by
in all my express applications.
@ejferg @SteveALee Please give it a try and let me know.
@SteveALee Unrelated to this issue, but you consider moving from express 2.x to express 4.x as express 2.x is no longer maintained and have security and performance issues (source: http://expressjs.com/2x/)
@SteveALee This package is good (and fast enough) for managing API endpoints with routing. If you need streaming feature, feel free to make a PR.. 😃 I know Azure Function is improving and may support streaming (soon or already?).
PS: Known workaround consisting in disabling x-powered-by
in the express application instance via app.disable("x-powered-by");
