vlasky:mysql

Reactive MySQL for Meteor

Provides Meteor integration of the mysql-live-select NPM module, bringing reactive SELECT statement result sets from MySQL >= 5.1.15.

NOTE: The version of mysql-live-select used by this package differs from numtel's original package in that result sets are treated as dictionaries rather than arrays. In this version, the identity of each row is determined by a LiveMysqlKeySelector that is passed into the select function.

NOTE: The version of mysql-live-select used by this package differs from wj32's forked package in that MySQL prepared statements are used instead of normal queries, for improved performance.

MysqlSubscription has been removed. To subscribe to a LiveMysqlSelect publication, use Meteor.subscribe().

For more information, see the original numtel:mysql package.

Server Implements

This package provides the LiveMysql class as defined in the mysql-live-select NPM package. Be sure to follow the installation instructions for configuring your MySQL server to output the binary log.

For operations other than SELECT, like UPDATE and INSERT, an active node-mysql connection (or pool) is exposed via the LiveMysql.db (or LiveMysql.pool) property.

LiveMysql.prototype.select()

In this Meteor package, the LiveMysqlSelect object returned by the select() method is modified to act as a cursor that can be published.

import { LiveMysql, LiveMysqlKeySelector } from 'meteor/vlasky:mysql';

var liveDb = new LiveMysql(Meteor.settings.mysql);

Meteor.publish('allPlayers', function(){
  return liveDb.select(
    `SELECT * FROM players ORDER BY score DESC`,
    null,
    LiveMysqlKeySelector.Index(),
    [ { table: 'players' } ]
  );
});

Tests / Benchmarks

A MySQL server configured to output the binary log in row mode is required to run the test suite.

The MySQL connection settings must be configured in test/settings/local.json.

The database specified should be an empty database with no tables because the tests will create and delete tables as needed.

If you set the recreateDb value to true, the test suite will automatically create the database, allowing you to specify a database name that does not yet exist.
