Retrieving jq results as one list object, vs a stream of members

Question

Hi i am trying in shell script to get a list of consul service tags for myApp passing nodes, using jq.

when i have something like this..

curl 'http://127.0.0.1:8500/v1/health/service/myApp?dc=a&passing=true' \
  | jq '.[].Checks[1].ServiceTags[]' 

output is..

"a"
"b"
"c"
"d"

I want to know if i could get it as a list. I want the output in this way..

 ["a","b","c","d"]

can you please suggest options..

Answer 1

Instead of

jq '.[].Checks[1].ServiceTags[]' 

Try

jq '[.[].Checks[1].ServiceTags[]]' 

The extra [] instruct jq to collect the values into an array.
See Array construction: [] in the jq Manual.
