Personalize the Loopback response following a successful save operation

I'm working on a Loopback 2.x application where I have models for Conversations and Messages, with a relationship of "Conversation has many messages." My goal is to receive a customized JSON response for the POST conversations/:id/messages endpoint, rather than the default response. I attempted to create a remote hook for the __create__messages method, but it didn't produce the desired outcome:

Conversation.afterRemote('__create__messages', function(ctx, next) {
  ctx.result.data = {
    success: 'yes'
  };
  next();
});

Despite this code, the default response still persists. How can I provide a custom JSON response for a remote method? Examples I've come across only cover customization at the model level or for all methods, such as in these resources: multiple models, multiple methods

Answer №1

Perhaps you could experiment with the code snippet provided below. It's important to note that manipulating data before a method finishes, rather than after, is crucial for achieving your desired outcome. Waiting until after the response has been created may hinder your goal. Feel free to test this out and let me know if it meets your requirements (make sure to replace any methods as needed for your specific case).

   Conversation.observe('before save', function(context, next) {
        var instance = context.instance || context.data;
        if (!instance) return next();
        // Your custom code here
        next();
      });
