Instance Method Summary collapse
-
#add_console_link_to_clipboard ⇒ Object
So use can quickly paste this into their browser if they want to see the function via the Lambda console.
-
#check_valid_json!(text) ⇒ Object
Exits with friendly error message when user provides bad just.
-
#client_context ⇒ Object
TODO: Hook client_context up and maek sure it works.
- #ensure_guesses_found! ⇒ Object
- #function_name ⇒ Object
- #guesser ⇒ Object
-
#initialize(provided_function_name, event, options = {}) ⇒ Call
constructor
A new instance of Call.
- #load_event_from_file(text) ⇒ Object
-
#local_run ⇒ Object
With local mode there is no way to bypass the guesser.
-
#puts(text) ⇒ Object
For this class redirect puts to stderr so user can pipe output to tools like jq.
- #remote_run ⇒ Object
- #run ⇒ Object
-
#transformed_event ⇒ Object
Returns text String for the lambda.invoke payload.

For this class redirect puts to stderr so user can pipe output to tools like jq. Example:
jets call posts_controller-index '{"test":1}' | jq .
