Update

Consider using this in index.js:

function checkConnection(response, callback) {
    if (!connect.connected) {
        connect.doConnection('simple', (err) => {
            if (err) {
                response.status(500).send({error: err});
                callback(false);
                return;
            }
        });
    }
    callback(true);
}

router.get('/all-data', function(request, response) {
    'use strict';
    console.log('AllData route invoked.');
    checkConnection(response, (result) => {
        if (result) {
            console.log('Calling getAllData');
            allMongo.getAllData(response);
        }
    });
});

Sending data with Fetch

const address = getByIndex(this.state.addressIndex);
const url = '/update' +
    '?id=' + address._id +
    '&address=' + JSON.stringify(address);

fetch(url)
    .then((data) => data.json())
    etc..
