Package Exports

cachedown

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cachedown) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cachedown

leveldown with a cache, for fast puts and gets

Usage

var slow = require('leveldown')
var fast = require('cachedown')
var levelup = require('levelup')

var db = levelup('./db.db', {
  db: function (location) {
    // careful! this db has a max cache size of Infinity!
    // to limit cache size, use fast(location, slow).maxSize(/* max size */)
    return fast(location, slow)
  }
})

// use db with better performance for puts and gets
db.put('hey', 'ho', function (err) {
  db.get('hey', function (err, val) {
    // val comes from internal cache
    console.log(val) // ho
  })
})

Misc

// 1

var leveldown = require('leveldown')
var levelup = require('levelup')
var cachedown = require('cachedown')
// set default leveldown
cachedown.setLeveldown(leveldown)
var db = levelup('path/to/db', { db: cachedown })

// 2

var cachedownInstance = new cachedown('path/to/db')
// change max size
cachedownInstance.maxSize(100)
// clear cache
cachedownInstance.clearCache()
