Transformation: Convert Response
We’ll need a JSON library to convert the response into a data structure. Searching hex.pm, I found the Erlang library jsx,[22] so let’s add its dependency to our mix.exs file.

| | { :jsx, "~> 2.0" } |
| | ] |
| | end |
Run mix deps.get, and you’ll end up with jsx installed.

| project/3/issues/lib/issues/github_issues.ex | |
| | def handle_response(%{status_code: 200, body: body}) do |
* | { :ok, :jsx.decode(body) } |
| | end |
