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,
  } ]
})
