mysql2-cache

✔ MySQL2 upgrade: cache queries, easy shortcuts, logging and debugging.

Installation

npm install mysql2-cache --save

Sample Usage

const mysql = require('mysql2-cache')
const db = mysql.connect({
  host: 'localhost',
  user: 'root',
  database: 'test',
  password: 'root'
})
db.q('SELECT * FROM test_table').then(res => console.dir)

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

Pass DEBUG=mysql2-cache* environment variable to pretty debug.

  mysql2-cache:1 SELECT * FROM test_table WHERE age > ? [1] +0ms
  mysql2-cache:1 ┌─────────┬─────────┬─────┐
  mysql2-cache:1 │ (index) │  name   │ age │
  mysql2-cache:1 ├─────────┼─────────┼─────┤
  mysql2-cache:1 │    0    │ 'Alice' │ 90  │
  mysql2-cache:1 │    1    │  'Bob'  │ 42  │
  mysql2-cache:1 └─────────┴─────────┴─────┘
  mysql2-cache:1  +32ms
