pedestal | For testing purpose | Content Management System library

this is my code:

I finished a pedestal clojure app and used the repl to start the server which it starts. I can only curl and can't access the project on any browser with localhost:8080. I did the frontend with Clojurescript/Shadowcljs which works fine in the browser, so it can't be an overall issue via localhost (a host issue).

To further check issues I followed step by step this tutorial app (just to be 100% sure), and it too only loads via curl and not in the browser as the tutorial states it should be able to load in the browser (not changing any code).

I am using Windows wsl2 with all my apps of varies languages but this one with clojure and pedestal won't load in the browser no matter if I even try the dockerfile included.

Thank You for any help you can give me on this situation because I am lost.

I am trying to build on the Pedestal tutorial app available here.

I am trying to add cljs functionality and trying to setup a unified clojurescript and clojure environment.

My deps.edn file looks as follows:

I am using the beginner guide in the pedestal guide but when trying to use use a namespace (require 'test) I get the following error messge: “Execution error (FileNotFoundException) at user/eval2012 (REPL:1). Could not locate test__init.class, test.clj or test.cljc on classpath.”

The same thing happens when trying (require 'hello)

I am using lein repl.

I have a directory called test and under src theres is a file called test.clj

test/src/test.clj:

First time poster and inexperienced coder here. I've wanted to make my Discord bot read the Binding of Isaac wiki to send information such as item descriptions when the user sends a command such as "!effect (itemname)"

Example:

User: !effect diplopia
Bot: Effect: Duplicates all pickups and pedestal items in the current room, then disappears.

Link used in example: https://bindingofisaacrebirth.gamepedia.com/Diplopia

I haven't tried too much since I don't know where to start, but I have looked around for quite a bit but it all either seems to complicated for someone of my skill level or unrelated to what I'm trying to do.

Any help is appreciated. Thanks in advance.

I've a Clojure application with Pedestal & Reitit and I need the origin header param to be mandatory.

So I want to format a file of strings which can span over multiple lines and are seperated by empty lines. The result should have every string in one line and remove the empty lines.

After some fiddeling I found this regex to be what I was searching for (\n)(?:[^\n]) but then I noticed that it also selects the first character from the next line which is bad.

Example lines:

I wrote a web service to generate estimates of Pi, using lazy sequences in Clojure and various infinite series formulae (Euler, Leibniz). The Clojure service sends these estimates over a Server-Sent Events channel. Currently a HTML/JS view is using Vue.js to consume the SSE events and display them.

It works pretty well as a service with a single node, as long as the connection for the SSE channel isn't closed. But as of now it doesn't persist or back up the state of the reductions (the position in the infinite series) to recover from a failure if the connection is closed or the service dies. Also, since the state is contained in local memory in the service (in the Clojure sequence value), there is no horizontal scalability, as there would be if the long-term memory state lived in Redis for example. In this case, just adding new nodes won't offer a way to actually divide the work -- it would just duplicate the same series. Using Redis to offload long-term memory state is the kind of setup I'm used to with stateless web services, to streamline a horizontal-scaling and fault tolerance strategy.

In this stateful case, I'm kind of at a loss as to how to scale the Clojure service with a distributed, multi-node solution, that could process series terms in parallel. Maybe there could be a dispatching "master" service that delegates sequence ranges to different nodes, receives the results from the nodes concurrently (via Redis pub/sub), aggregates them mathematically and yields a resulting SSE stream for the view? And in that case, the master service would use an infinite series of numbers spaced by about a thousand, to yield the range bounds, which the parallel nodes could use to initialize non-infinite Clojure sequences (likely still lazy)? Surely in this case I'd need to mark which sequence ranges are complete as they come in, with a retry strategy in the case of node failure during the processing of a range.

I am studying Kubernetes Stateful Sets to become familiar with deployment patterns for stateful services, though I haven't yet encountered a pattern or solution that fits this specific problem. Were this a stateless service, the Kubernetes solution would be kind of obvious, but a stateful approach leaves me with a blank slate in the Kubernetes environment.

Can anyone point me in a good direction for the architecture here? Assuming I do want to keep the state of series terms encapsulated in Clojure lazy sequences (that is, in local service memory), am I on the right track in my strategy to divide the work?

Here is the relevant code for the single-node Clojure service:
