knex-multiconnect v0.1.0

Knex MultiConnect

Introduction

The small library is designed to help manage multiple connection pools when using the Knex SQL builder library. Most often, the need for multiple connections arises when using a database that contains slaves that act as read-only replicas. With this library, you can register multiple Knex instances that are associated with a type: read or write. When you need to make a query, you can select to use a connection that is marked as either read or write, depending on the type of query you intend to execute.

Usage

Using the library simply requires you to create a Knex instance, register it with the library, then call whichever type of connection you need.

  const KnexManager = require('knex-multiconnect').default

  const KM = new KnexManager();

  KM.registerInstance('read', knex) //knex is an existing knex instance, not shown to save space
  
  KM.read().knex('users').select().then((res) => {
    console.log(res)
  })

  KM.destroyAllInstances()
