Event parameter validation
Similar to action parameter validation, the event parameter validation is supported.
Like in action definition, you should define params in even definition and the built-in Validator validates the parameters in events.
// mailer.service.js
module.exports = {
name: "mailer",
events: {
"send.mail": {
// Validation schema
params: {
from: "string|optional",
to: "email",
subject: "string"
},
handler(ctx) {
this.logger.info("Event received, parameters OK!", ctx.params);
}
}
}
};The validation errors are not sent back to the caller, they are logged or you can catch them with the new global error handler.
