mysql(connectionString, [options])

• connectionString: Mysql2 connection string, e.g. {host:'localhost', user: 'root', password: 'test', database: 'test'}
• options: Object, You can overwrite the method used to call this wrapper. By default your call is: ctx.myPool().query, you can overwrite this by passing an option: { method: 'mysql' }. That way, you can call ctx.mysql.query().

query(queryString, argument, options)

• queryString: select * from user.
• argument: Default: [], replace value on ? prefix, select * from user where active=?, [true]
• options: Object, if you need column name then you can pass option: { field: true }. Default: { field: false }

Usage

import Koa from 'koa'
import mysql from 'koa2-mysql-wrapper'

const app = new Koa()

app.use(mysql({host:'localhost', user: 'root', password: 'test', database: 'test'}))

app.use(async (ctx, next) => {
  let query = await ctx.myPool().query('SELECT * FROM `table` WHERE `name` = ? AND `dead` = ?', ['James', 0])
  await next()
})

Supported

• Array values: ctx.myPool().query('SELECT * FROM 'table' WHERE 'name' in (?) AND 'dead' = ?', [['James', 'Collyer'], 0]), notice that it supports only 1 nested array.

Thanks for supporting me. If you find any issue or need any special modules, please report to me so I can improve and maintain for a better module.
