Can anyone point me in the right direction for coercing a request parameter that has the inst? spec attached? We’re using json-transformer and the payload is JSON

jaime.sangcap18:04:10

Do you have the middleware and coercion in the route data? Then I think you just need to have the request header content-type to "application/json"?

ikitommi04:04:03

yes, it should just work if you have the coercion configured on. examples have good starting point with the needed mw configuration (and to test stuff)

hello all. Can't seem to find in the documentation how to declare optional query parameters by default all parameters are defined as required

{:swagger {:tags ["path"]}
          :get     {:summary    "Forward Path Search"
                    :parameters {:query {:src string? :dst string? :network string?}
                                 }
                    :handler    (fn [{{{:keys [src dst network]} :query} :parameters}]
                                  (path/path-search-handler src dst network))
                    }}

jaime.sangcap18:04:03

I'm trying to learn spec myself as well, it may not be the best solution. Assuming src and dst are required, and network as optional.

(s/def ::src string?)
(s/def ::dst string?)
(s/def ::network string?)

# Then define parameters as
{:parameters {:query (s/keys :req-un [::src ::dst] :opt-un [::network])}
EDIT: s here is
[clojure.spec.alpha :as s]

gary00118:04:43

ahh that worked

"in": "query",
"name": "network",
"description": "",
"type": "string",
"required": false

glad to help 🙂

ikitommi04:04:52

you can also use ds/opt if you use the data-spec syntax, see https://cljdoc.org/d/metosin/spec-tools/CURRENT/doc/data-specs

ikitommi04:04:30

a doc PR would be awesome to have an example of optional parameter, in both ways. Would anyone have time for that?

jaime.sangcap08:04:34

@ I'll review the docs, and see if I can contribute an example. Just for clarification, what do you mean by "in both ways"?

ikitommi08:04:58

looking forward! with both way, I mean - using data-specs and normal spec1 keys syntax for optional keys

ikitommi08:04:54

(optional keys should be documented also for plumaric schema and malli, but that’s a separate thing)

Funny when you join a channel to ask a question, and it’s just been answered 🙂

Hello! Can I use clj-ajax with reitit to get data from backend or I must use reitit on both frontend and backend? Sorry for the probably noobish question, but I'm really tired of all this frontend stuff 😓
