Cache queries

const mysql = require('mysql2-cache')
const db = mysql.connect({
  host: 'localhost',
  user: 'root',
  database: 'test',
  password: 'root'
})
db.q('SELECT * FROM test_table WHERE id=?', 1, true) // use cache with default ttl=300s
db.q('SELECT * FROM test_table WHERE id=?', 1, true, 300) // ttl in seconds

Debugging easy
