Query Alfresco Data as a MySQL Database in Node.js

Execute MySQL queries against Alfresco data from Node.js.

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

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

Create a Virtual MySQL Database for Alfresco Data

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

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

    To connect to Alfresco, the following connection properties must be supplied: User, Password, and InstanceUrl. User and Password correspond to the login credentials that you use to access Alfresco in a web browser. InstanceUrl corresponds to the Alfresco instance you will be querying. For instance, if you expect your queries to hit https://search-demo.dev.alfresco.me/alfresco/api/-default-/public/search/versions/1/sql, you should supply search-demo.dev.alfresco.me for InstanceUrl.

  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 Alfresco data from any MySQL client.

Query Alfresco from Node.js

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

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

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

connection.end();
