Why not clear dict/json? How I can get len clients?

I believe len only works on array. Though I am interested in this API now, I tried looking for a way but can't find one. Even GJson doesn't seem to have a way around this.

For clarity's sake, Author is trying to get the length of clients which is an object, not an array:

"clients": {
    "84:c5:a6:2b:42:42": { }
    "f2:74:41:ef:c1:89": { }
}

Referencing PR: #746

[ralphocdol]

@CakesTwix as @svilenmarkov mentioned, there really was a way already to do this: #746 (review)

Number of entries: {{ $req.JSON.Int "result.1.clients|@keys|#" }} 

{{ range $req.JSON.Array "result.1.clients|@keys" }}
  <div>{{ .String "" }}</div>
{{ end }}
