Localforage module for Nuxt.js

📖 Release Notes


  1. Add @nuxtjs/localforage dependency to your project
yarn add --dev @nuxtjs/localforage # or npm install --save-dev @nuxtjs/localforage
  1. Add @nuxtjs/localforage to the buildModules section of nuxt.config.js
export default {
  buildModules: [
    // Simple usage

    // With options
    ['@nuxtjs/localforage', { /* module options */ }]

:warning: If you are using Nuxt < v2.9 you have to install the module as a dependency (No --dev or --save-dev flags) and use modules section in nuxt.config.js instead of buildModules.

Using top level options

export default {
  buildModules: [
  localforage: {
    /* module options */

  • Default: [localforage.INDEXEDDB, localforage.WEBSQL, localforage.LOCALSTORAGE]

The preferred driver(s) to use. Same format as what is passed to setStorageDriver(), above.

  • localforage.INDEXEDDB
  • localforage.WEBSQL
  • localforage.LOCALSTORAGE

Advanced Usage

You can register multiple instances, see below:

// nuxt.config.js

  buildModules: [
  localforage: {
    instances: [{
      name: 'myApp',
      storeName: 'images'
    }, {
      name: 'myApp',
      storeName: 'fileSystem'
