This is a Google Firebase driver for Chego library.

Usage

All you need to do to ensure that your queries are served by Google Firebase, simply create a new Chego object using the chegoFirebase and configuration object.

const { newChego } = require("@chego/chego");
const { chegoFirebase } = require("@chego/chego-firebase");
const chego = newChego(chegoFirebase, {
    apiKey: "xxxxxxxxxxxxxxxxxxxx",
    authDomain: "some-domain.firebaseapp.com",
    databaseURL: "https://some-domain.firebaseio.com",
    projectId: "some-domain",
    storageBucket: "some-domain.appspot.com",
    messagingSenderId: "3252523423"
});

await chego.connect();
const query = newQuery();

query.select('*').from('superheroes').where('origin').is.eq('Gotham City').limit(10);

chego.execute(query)
.then(result => { 
    console.log('RESULT:', JSON.stringify(result));
    chego.disconnect();
})
.catch(error => { 
    console.log('ERROR:', error); 
    chego.disconnect();
});

Features

custom conditions

If you want to check the complex condition for several object properties - without additional queries for object details, you can write a function and use it inside the where clause. This function must return a value that can be compared with additional conditions such as eq.

Check the example: We want to know which superhero is 100 km from Batcave. For this we need to know their current position and distance from the Batcave.

const getSuperheroDistanceFrom = (position) => (heroData) => {
     return ... math magic with position & heroData.position
}
query.select('*').from('superheroes').where(getSuperheroDistanceFrom({lat:42.762488, ,lng:-83.283120})).is.lt(100000);
