The website or mobile app is the storefront for participating in the modern digital era. It’s your portal for inviting users to come and survey your products and services. Much attention focuses on front-end development; this is where the HMTL5, CSS, and JavaScript are coded to develop the landing page that everyone sees when they visit your site.

But the real magic happens on the backend. This is the ecosystem that really powers your website. One writer has articulated this point very nicely as follows:

The technology and programming that “power” a site—what your end user doesn’t see but what makes the site run—is called the back end. Consisting of the server, the database, and the server-side applications, it’s the behind-the-scenes functionality—the brain of a site. …

Let's explore how to deploy a node.js app with MySQL backend on the Oracle Cloud. I want to cover several aspects:

• How to deploy and initialize a MySQL instance
• How to adapt the source code
• How to deploy the application
• How to scale the application

There are different ways to configure this. I tested the easiest deployment with MySQL Cloud Service and the Application Container Cloud for the node.js part. All configurations are done via the cloud web GUI. There is also a REST interface available. But let's keep that for later.
If you don't have access to the Oracle Cloud you can get a trial access here.
How to deploy a MySQL instance Once you logged into the Oracle cloud you can create new instances from the dashboard. The following screenshots describe the process.

I am starting a series of videos on the MySQL Document Store. The Document Store allows those who do not know Structured Query Language (SQL) to use a database without having to know the basics of relational databases, set theory, or data normalization. The goal is to have sort 2-3 minute episodes on the various facets of the Document Store including the basics, using various programming languages (Node.JS, PHP, Python), and materializing free form schemaless, NoSQL data into columns for use with SQL.

The first Episode, Introduction, can be found here.

Please provide feedback and let me know if there are subjects you would want covered in the near future.

MySQL Connector/Node.js is a new Node.js driver for use with the X
DevAPI. This release, v8.0.7 , is the first development release of the
MySQL Connector/Node.js 8.0 series.

The X DevAPI enables application developers to write code that combines
the strengths of the relational and document models using a modern,
NoSQL-like syntax that does not assume previous experience writing
traditional SQL.

MySQL Connector/Node.js can be downloaded through npm (see
https://www.npmjs.com/package/@mysql/xdevapi for details) or from
https://dev.mysql.com/downloads/connector/nodejs/.

To learn more about how to write applications using the X DevAPI, see

In previous blog posts we explained how to perform certain actions in a MySQL database set up as a document store using Connector/Node.js. In this blog post we are going to use some of the examples covered to explain how to start working with an application created with Express.js, AngularJS, Node.js, and MySQL Connector/Node.js.

Required

• Node.js
• Express.js
• AngularJS
• MySQL Connector/Node.js
• MySQL Server 5.7.12 or higher

Optional

• …

MySQL Connector/Node.JS 1.0.4 was recently released as a development milestone release. This is the first version available via npmjs.com. npmjs.com is the central registry for Node.JS packages. This and potential future official MySQL packages can be found using the @mysql organisation. For this to work we had to change the package name to contain that prefix and have chosen the name @mysql/xdevapi as this package provides the implementation of our X DevAPI for Node.JS and we have a free namespace for potential future libraries as part of our Connector/Node.JS product.

Given an existing Node.JS project we can easily install the library:

$ npm install --save @mysql/xdevapi …

In the previous blog post we explained how work with the collection CRUD operations. In this blog post we are going to explain other functions that are related to document management.

We already know how to create collections, as well as how to add, delete, update and retrieve documents from them. But, how can we add a new field to a document or documents that are in a collection?

The following code demonstrates how to do it:

var mysqlx = require('mysqlx');
mysqlx.getSession({
  host: 'host',
  port: '33060',
  dbUser: 'root',
  dbPassword: 'my pass'
}).then(function (session) {
  var schema = session.getSchema('mySchema');
  var coll = schema.getCollection('myColl');
  var query = "$.name == 'NewField'";
  var newDoc = { name: 'NewField', description: 'a new field', 
                 extra: ['hello', 'world'] …

In the previous blog post we explained how to create schemas and collections. In this one we are going to explain how to work with collections: adding, updating and deleting documents.

The following code demonstrates how to add a single document to an existing collection:

var mysqlx = require('mysqlx');
mysqlx.getSession({
  host: 'host',
  port: '33060',
  dbUser: 'root',
  dbPassword: 'my pass'
}).then(function (session) {
  var schema = session.getSchema('mySchema');
  var coll = schema.getCollection('myColl');
  var newDoc = { name: 'Test Name', description: 'Test Description' };

  coll.add(newDoc).execute().then(function (added) {
    console.log('Document(s) added: '
                + added.getAffectedItemsCount());
    session.close();
  })
  .catch(function (err) {
    console.log(err.message);
    console.log(err.stack); …
