CData Connect



Execute MySQL queries against Kintone data from Node.js.

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

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

Create a Virtual MySQL Database for Kintone Data

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

  1. Login to Connect Cloud and click Databases.
  2. Select "Kintone" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Kintone.

    In addition to the authentication values, set the following parameters to connect to and retrieve data from Kintone:

    • Url: The URL of your account.
    • GuestSpaceId: Optional. Set this when using a guest space.

    Authenticating with Kintone

    Kintone supports the following authentication methods.

    Using Password Authentication

    You must set the following to authenticate:

    • User: The username of your account.
    • Password: The password of your account.

    Using Basic Authentication

    If the basic authentication security feature is set on the domain, supply the additional login credentials with BasicAuthUser and BasicAuthPassword. Basic authentication requires these credentials in addition to User and Password.

    Using Client SSL

    Instead of basic authentication, you can specify a client certificate to authenticate. Set SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword. Additionally, set User and Password to your login credentials.

  4. Click Test Database.
  5. 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 Kintone data from any MySQL client.

Query Kintone from Node.js

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

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

Connect to Kintone 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 : 'kintonedb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Comments', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
