Query Dropbox Data as a MySQL Database in Node.js

You can use CData Connect Server to query Dropbox data through a MySQL interface. Follow the procedure below to create a virtual database for Dropbox in Connect Server and start querying using Node.js.

CData Connect Server provides a pure MySQL, cloud-to-cloud interface for Dropbox, allowing you to easily query live Dropbox data in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to Dropbox, leveraging server-side processing to quickly return Dropbox data.

Create a Virtual MySQL Database for Dropbox Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect Server and click Connections.
2. Select "Dropbox" from Available Data Sources.
3. Dropbox uses OAuth to authenticate. Click Connect to authenticate with Dropbox.
4. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Dropbox data from any MySQL client.

Query Dropbox from Node.js

The following example shows how to define a connection and execute queries to Dropbox with the MySQL module. You will need the following information:

• Host name, or address, and port: The address of your instance of the Connect Server (myinstance.cdatacloud.net) and the port (3306)
• Username and password: The username and password of a user you authorized on Connect Server
• Database name: The database you configured for Dropbox (dropboxdb)

Connect to Dropbox data and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'dropboxdb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Files', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
