app-context-mysql2

mysql2 initializer for app-context

Usage

This initializer can be auto-installed by using it in your context file.

This initializer will attach the configured connections to APP.mysql.

module.exports = function() {
  this.runlevel('connected')
    // attach a connection to APP.mysql - use the value at APP.config.mysql as the connection string
    .use('mysql2', '$mysql')
 
    // attach a connection to APP.mysql
    .use('mysql2', 'mysql://localhost:3306/foobar')
 
    // attach a connection pool to APP.mysql
    .use('mysql2', {url: 'mysql://localhost:3306/foobar', pool: true})
 
    // create 2 connections and attach them as an object to APP.mysql
    // this will create APP.mysql.users and APP.mysql.data
    .use('mysql2', {
      users: '$mysql.users',
      data: '$mysql.data'
    })
 
    // you can also pass options to each connection
    .use('mysql2', {
      users: {url: 'mysql://localhost:3306/users', pool: true},
      data: {url: 'mysql://localhost:3306/data', connectTimeout: 3000}
    })
};

Connection Configurations

Each connection can be configured with either a connection string (like mysql://localhost:3306/users) or with an object. The object will be passed through to the mysql constructor and can consist of any options from connection options. There is a special url option not listed that this initializer will parse and fill in for you (like the user, password, host, and port).

Connection Pooling

You can make any connection a pool by adding {pool: true} to the configuration. Other options from the configuration will be passed through to the mysql driver. You can see the available options at connection options and pool options.
