# Cloud DB Access on TOIT
Below description of modified application https://github.com/mk590901/toit-rest-api. The application additionally saves meteo information to the cloud in __Firebase Realtime Database__.
## Introduction
The application is a clone of the previously mentioned application, which allows you to receive specific meteorological information upon request from a third-party __MQTT__ client for some geographic point. The received information is also saved in the __Firebase RealTime DataBase__ on the cloud now.
This saved data is shown below in the movie on the __Firebase console__.
## Brief description
There are two things to pay attention to in the application:
* Construction of a json object for sending to the DB: several procedures in the __utils.toit__ file, which are used after receiving weather data in __weather.toit__ module.
* The __send_firebase__ procedure in __firebase.toit__ file, which implements sending data to __Firebase Realtime Database__.
## Implementation
The application consists of two parts:
> MQTT client in the _mqtt_bridge.toit_ file, which allows
* Receive data for a request pair [city, country code]. For example, "Tokyo, JP", "Jerusalem, IL" or "Rovaniemi, FI",
* Create and execute a request using the __doneRequest__ function and send the received weather data to the desired topic via the __MQTT__ bridge.
* By means __getJson__ function to get a __json object__ that contains data to add to the __Firebase Realtime Database__.
* Finally, the __send_firebase__ function performs posting data to add them to the cloud.
> The __doneRequest__ function, in the _weather.toit_ file, which receives data for a request and returns a json string with current weather data. In parallel, this function generates data in a form suitable for storage in the __Firebase Realtime Database__.
NB! Details on using __HTTP__ requests in __TOIT__ can be found at https://docs.toit.io/tutorials/network/http.
