Fast, Effect, Simple Web Framework for Crystal. Help Kemal development https://www.patreon.com/sdogruyol
I'm getting really weird CORS issues now. Anybody here able to successfully enable CORS? This is what I'm adding in Kemal:
before_all do |env|
env.response.headers["Access-Control-Allow-Origin"] = "*"
end
static_headers do |response, filepath, filestat|
response.headers.add("Access-Control-Allow-Origin", "*")
end
Anyone else have problems with serving javascript from public directory? (Using Firefox browser) My web pages never finish loading. But it only happens for certain scripts. If I create my own javascript file it seems fine, but jquery, for instance, won't load. Even if I try it directly,
http://0.0.0.0:3000/jquery.js, the whole script will appear on the page, but the spinner never stops spinning.
Got issue with web socket on 0.35.1 reserved1 = 0, reserved2 = 1, reserved3 = 0, see crystal-lang/crystal#9522. Rollback to 0.34.0 solve the issue.
IMO might be Kemal issue, see crystal-lang/crystal#9484 re WebSocketHandler
@grkek resolved all issues when I merged mamontha's kemalcr/kemal#576 and kemalcr/kemal#577 into my own fork
Still looking for those PRs to be merged into the upstream for kemal to work on 0.35.1
Whenever the client communicates with the server, the socket disconnects - seems to be similar to: kemalcr/kemal#577
anyone know when @xavi's fix will be pushed, it seems to fix it?
It got me into Crystal :+1:
There wasn't many bugs really, hopefully maintainers will keep it compatible with the latest crystal

I wouldn't like to downgrade crystal. does this mean that I need to manually edit the dependency?
Crystal 0.35.1 [5999ae29b] (2020-06-19)
just tangencial, but the whole mindset of looking as nginx and varnish as an holly grail of speed that you can put in front of crappy slowly software is quite telling of the current state of server technologies. Not trying to be overly negative. I love nginx.
I've heard of several people exposing their kemal applications directly to the internet. The reason most people put said proxies in front of their apps is usually their absurd scale limitations
anyways, Here's a suggestion for the guides: Add an example of how to put the code inside a module and a class and how to handle objects whose lifetime transverses the request scopes. Database connections handles, etc. Such examples exist, for example in the websocket example, but they only work with the code placed directly as main code.
And here's a suggestion for kemal generaly: provide a way to add routes grammatically by calling a method. The current macros are great for many applications and have a lovely simple syntax. But they don't play well with things like loading route configurations from a file and so on. They force routes to be hardcoded at compiletime.
This can be done without breaking current functionality. Most python micro-frameworks do this. They provide an anotation based route definition, but you can still call the method used to add a route manually.

Hey everyone, I would like to leave a thank you note for sdogruyol and others that made and maintained kemal. This was a very usefull piece of software for me. I used it a few times to create small http services. Great simplicity and lightness. To the point as it should be. As it seams that the community is loosing steam, I will migrate the only active project I have that uses it to use crystal's built in web server library. I think this would be a useful piece of software as it is, but crystal is still not stable enough to guarantee an acceptable level of forward compatibility of projects like this one. Thank you! We absolutely need more pragmatism and simplicity like that shown in this project in the IT world.
