Fortune-indexeddb NPM

Fortune IndexedDB

This is an IndexedDB adapter for Fortune.js. Various performance and compatibility optimizations are included:

Runs in a Web Worker so that database operations don't block the main thread, and uses MessagePack for messaging.
Lazy loads records as they're requested and keeps them in memory.
Primary keys are universally unique, which solves some compatibility problems.

$ npm install fortune-indexeddb

Usage

This module works in web browsers only, and falls back to memory if IndexedDB is not available:

const fortune = require('fortune')
const indexedDBAdapter = require('fortune-indexeddb')

const store = fortune(recordTypes, {
  adapter: [ indexedDBAdapter, {
    // Name of the IndexedDB database to use. Defaults to `db`.
    name: 'db',
    // These are optional to implement, if storage compression is needed.
    compress: uint8array => uint8array,
    decompress: uint8array => uint8array,
  } ]
})
