SailsJS : How to convert camel case to snake case in JSON response implicitly?

Question

Is there a way in sails.js to convert camelCase to snake_case while returning the JSON response using res.ok(data), where data is an object, without having explicit getters or setters in the model to do this?

Answer 1

There is also another solution that don't need to be implemented in each response.

You can define your custom hook in api/hooks folder with following content:

var snakeCase = require('snake-case');

module.exports = function (sails) {
  return {
    routes: {
      after: {
        'all /*': function overrideJsonx(req, res, next) {
          var jsonx = res.jsonx;
          res.jsonx = function (obj) {
            var res = snakeCase(obj);
            jsonx(res);
          };

          next();
        }
      }
    }
  }
};

It will work for all responses without modifying custom responses in api/response folder.
