transducer / cljs-iota Goto Github PK

First let me say I really like using cljs-iota in cljs and I had no problem using it until this.

I'm having trouble with returning a value from a callback.

My code is:

(defn find-transactions
"search transactions associated with an address and return a vector of hashes"
[]
(println "finding transactions")
(iota-api/find-transactions iota-instance {:addresses (list address-to-search)} find-transactions-callback)
)

And the callback function is:

(defn find-transactions-callback [err hashes]
(prn "transactions found" hashes)
hashes
)

I expect this to return a vector of hashes, but i got undefined.

If I do
(.log js/console "hashes are" (find-transactions))

The callback prints to the console :

"transactions found" ["JW9QTNHDLGQYKGHLYHWHYRKTTEVUVBZSHNMLCDLBWVYPROKTCDRAMFGXMIQCEM9YIRXUSZJTEKG999999" "QYKZWELJYAMWPITSTZSXLFFERSGRPBKIOCHSE9KLENRXNBXSGSLBEYW9JUVJYP9QWBJJFKMSUDA999999"]
which means it retrieves the result that I want, but console.log prints

"hashes are" undefined

I don' t know why it doesn't return the vector of hashes.

PS: I can't return anything from the callback. Even doing

(defn find-transactions-callback [err hashes]
"hello"
)

doesnt work. If I do ((.log js/console "hashes are" (find-transactions)) i got " hashes are" nil.

PS2 : I do exactly the same with get-new-address and in the callback i do
(fn [err address] (first address))
and it returns the first address of the vector.

Do you have any idea why?
