Filter the response of an action with output

Total.js 5 · total5@0.0.19 actionssecurity Executed against Total.js 5

output has the same syntax as input, but it is applied to the response: only the declared fields are sent, converted to their types. Declare it on every action that reads from a database and you cannot leak a field by accident.
