Error Handling

Most of SDK's functions report their success or failure using an object with callbacks.

JavaScript

auth
  .passwordResetByMail("admin@example.com")
  .then(() => {
    // This function will *not* be called in case of `Error`.
  })
  .catch((error) => {
    // This will be called.
    // error is an instance of DrupalError with details about the error.
    if (error.getErrorCode() === DrupalError.CONNECTION_FAILED) {
      alert("Uh oh, connection failed! please try again later.");
    }
    if (error.getErrorCode() === DrupalError.INVALID_JSON) {
      alert(
        "Uh oh, recieved invalid response from server! \
            Please contact administrator."
      );
    }
  });
