This method is a syntactic sugar for calling a $lambda action.
The syntax is as follows:
{
"trigger": "twitter.get",
"options": {
"endpoint": "timeline"
},
"success": {
"type": "$render"
},
"error": {
"type": "$util.toast",
"options": {
"text": "Uh oh. Something went wrong"
}
}
}
Above is a syntactic sugar for the below "$lambda" type action call:
$lambda action is a special purpose action that triggers another action by name and waits until it returns.
This way we can define a huge size action somewhere and simply call them as a subroutine and wait for its return value.
When the subroutine (the action that was triggered by name) returns via `"type": "$return.success"` action,
the $lambda action picks off where it left off and starts executing its "success" action with the value returned from the subroutine.
Notice that:
1. we get rid of the "trigger" field and turn it into a regular action of `"type": "$lambda"`.
2. the "trigger" value (`"twitter.get"`) gets mapped to "options.name"
3. the "options" value (`{"endpoint": "timeline"}`) gets mapped to "options.options"
{
"type": "$lambda",
"options": {
"name": "twitter.get",
"options": {
"endpoint": "timeline"
}
},
"success": {
"type": "$render"
},
"error": {
"type": "$util.toast",
"options": {
"text": "Uh oh. Something went wrong"
}
}
}
The success / error actions get executed AFTER the triggered action has finished and returns with a return value.

1. Trigger was just for one-off triggering and finish. Lambda waits until the subroutine returns and continues where it left off.

1. Triggers another action by name
2. Waits for the subroutine to return via `$return.success` or `$return.error`
3. When the subroutine calls `$return.success`, continue executing from `success` action, using the return value from the subroutine
4. When the subroutine calls `$return.error`, continue executing from `error` action, using the return value from the subroutine
