mysql-db

MySQL Database Wrapper

MySQL database modeling with built in CRUD. Just create your models, then get up and running.

Installation - Node

npm install --save mysql-db

---

Environmental Variables

Configuration

• NODE_ENV - will use test environmental variables if NODE_ENV=test

• SHOW_DEBUG - if true, will show log messages

• DB_HOST

• DB_USER

• DB_PASSWORD

• DB_DATABASE

If NODE_ENV is "test", then the following environmental variables will be used:

• DB_TEST_HOST
• DB_TEST_USER
• DB_TEST_PASSWORD
• DB_TEST_DATABASE

Usage

To use this package to connect to your database you must first:

1. Setup the environmental variables to connect to your database
2. Create a new model for every CRUD table/view (and set up any defaults for new rows and for updates)
3. Use CRUD on your model as you please!

Create a new CRUD model

var Database = require('mysql-db');

var pages = new Database.crud({
	schema: {
		select: [
				'id',
				'slug',
				'title',
				'category',
				'content',
				'created',
				'modified',
				'tags'
		],
		from: 'pages'
	}
});

// default values that will be added to every create/new row inserted
pages.setCreateDefaults({
	created: "UTC_TIMESTAMP()",
	modified: "UTC_TIMESTAMP()"
});

// default values that will be added to every row update
pages.setUpdateDefaults({
	modified: "UTC_TIMESTAMP()"
});

module.exports = pages;

Use the new model to get data

pages.get({},function(err,result){
	// Do stuff
	console.error(err);
	console.log(result);
});

Edit/update fields in the database

pages.update({
	edit: {
		title: 'hi'
	},
	criteria: {
		id: 1
	}
},function(err,result){
	// get response
});

Note: In this example, the modified field is automatically set to UTC_TIMESTAMP() since we previously defined the default when creating the pages model (by using pages.setUpdateDefaults)

Delete an entry

pages.delete({
	id: 3
}, function(err,result){
	// get response
});

Insert/create an entry

pages.create({
	id: 25,
	title: 'hello world',
	content: 'it is a wonderful day!'
},function(err,result){
	// get response
});

Note: In this example, the created and modified are automatically set since we previously set them with pages.setCreateDefaults when defining the model
