echo #

Description #

The echo filter is used to output specified characters in the returned result. It is often used for debugging.

A simple example is as follows:

flow:
  - name: hello_world
    filter:
      - echo:
          message: "hello infini\n"

The echo filter allows you to set the number of times that same characters can be output repeatedly. See the following example.

...
   - echo:
       message: "hello gateway\n"
       repeat: 3
...

Name	Type	Description
message	string	Characters to be output
repeat	int	Number of repetition times
stdout	bool	Whether the terminal also outputs the characters. The default value is `false`.
