How to read a key value after decoding json in erlang -

here short query

in erlang parsed json using

ccode = jiffy:decode(<<"{\"foo\": \"bar\"}">>). 

it returns

{[{<<"foo">>,<<"bar">>}]} 

now target value of 'foo' , should return 'bar'

any appreciated.

you can extract list of attributes of json object using pattern matching , find value key in resulting list:

{attrs} = jiffy:decode(<<"{\"foo\": \"bar\"}">>), foovalue = proplists:get_value(<<"foo">>, attrs).
