Guys, do you know how to find Clojurescript React and React-Native template to buy ?

Hi re-framers! I'm working my way through the todomvc example ( https://github.com/Day8/re-frame/tree/master/examples/todomvc ), and could use some insights.. So, our goal should be to have all of application state in app-db, so that the view can be derived from that only source. Despite this, there are some properties that are defined as "component-local" ratoms, such as the editing flag at https://github.com/Day8/re-frame/blob/01c63cc4b30591510acf415479b8e6d0614d5c1b/examples/todomvc/src/todomvc/views.cljs#L29 . This way app-db is no longer a definitive app state store, is it? Or, should we not consider "editing" to be part of the application state? If so, how do you decide what is state (as in: part of app-db) and what isn't...?

Hey friends, I'm trying to initiate a save file dialogue using day8-re-frame.http-fx. I see that hte file is being downloaded in the network tab as I can see the preview. But I'm unsure of how to handle this

(rf/safe-reg-event-fx
 :download-something
 (fn [{:keys [db]} _]
   {:http-xhrio {:method :get
                 :uri "/test"
                 :on-success [:do-something]
                 :on-failure [:do-somethingelse]
                 :format (ajax/transit-request-format)
                 :response-format (ajax/transit-response-format)}}))

Hi @petr, I think your server should return the response with Content-Disposition header. https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition

Hmm that might be it

I'll give that a shot

Even with that header it still doesn't appear to work

HTTP/1.1 200 OK
Content-Type: image/png
Content-Disposition: attachment
X-Xss-Protection: 1; mode=block
X-Frame-Options: SAMEORIGIN
X-Content-Type-Options: nosniff
Content-Length: 51601
Server: http-kit
Date: Mon, 25 Feb 2019 16:22:32 GMT

One option is to use a js-library such as https://github.com/eligrey/FileSaver.js/ to handle the download. Though (AFAIK) Content-Disposition header is the preferred way when the file comes from the server.

Try providing also filename=“something.png” in the header

Content-Disposition: attachment; filename="something.png"

Oh I see what's happening

Ehhh, the problem is probably that you can’t trigger file download with AJAX-request.

So if I take a look inside of my on-failure handler. There is this:

"EEEEEEEEEEEEE" {:response nil, :last-method "GET", :original-text "����JFIF���\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b\...

You could just href to the endpoint?

It looks like its getting the binary data, but I need to push that to a file for the user to enter the dialogue

I can use an href

That would probably be the best.

But I like this more as I can theoretically handle 400s - 500s

Though.. It’s possible also to get the blob from Ajax-request and hand it over to filesaver.js and let it do some magic to popup the dialog

@petr you can check this out https://github.com/lipas-liikuntapaikat/lipas/blob/dev/webapp/src/cljs/lipas/ui/reports/events.cljs#L52-L76 and https://github.com/lipas-liikuntapaikat/lipas/blob/dev/webapp/src/cljs/lipas/ui/effects.cljs#L17-L20

Oh yes

This is exactly what I needed

Thank you so much

Np!

Hello everyone,How to dispatch events from figwheel REPL ? #newbie-question #help

when i dispatch above code from REPL? I get error "RuntimeException Invalid token: ::events/initialize-db"

@anish.developer the double colon in ::events/initialize-db refers to an alias. If for example you were to require a namespace such as (require '[my-re-frame.events :as events]) the keyword ::events/initialize-db would then expand to a fully qualified keyword :my-re-frame.events/initialize-db. So it depends on how your reg-event-db is defined, if you have used something like :events/initialize-db (with a single colon) then it is already fully qualified and you can just use it as is with the single colon, if you defined it like ::initialized-db then it will take on the name of the current namespace and you with have to either refer to the the fully qualified key or alias the namespace using require.

thanks @sofra

@sofra i have defined db as follows

so if i have dispatched event like (re-frame/dispatch-sync [:my-re-frame.events/initialize-db]) which is equivalent to (re-frame/dispatch-sync [::events/initialize-db])

i get error "event handler registered for: :my-re-frame.events/initialize-db"

i think its because of "::"

now i am bit confused about namespaces
