What is the behavior of an AngularJS controller when it encounters the res.json(false) value?

In my AngularJS controller, I am sending an HTTP request to an API. The API can respond with either res.json(true) or res.json(false) depending on a certain condition.

However, it seems like the controller is not handling this as expected. I am interested in seeing how someone else might approach this:

function MyCtrl($scope, $http) {
  $http.get('/api/call').
    success(function(data, status, headers, config) {
      console.log(data); // --> This outputs false
      if (data) { // --> Here, I would expect this to fail, but it does not
        console.log("true"); // --> This also gets displayed
      }
    });
  1. Should I change the response from the API so that it returns something different than res.json(false)?
  2. Should I update the code above to check for if (data === false) instead?

Answer №1

sendResponse(true) // not in JSON format
sendResponse({ status: true }) // in JSON format
