Localforage module for Nuxt.js

📖 Release Notes

Setup

1. Add @kalligator/nuxtjs-localforage dependency to your project

npm install --save-dev @kalligator/nuxtjs-localforage

2. Add @kalligator/nuxtjs-localforage to the buildModules section of nuxt.config.js

export default {
  buildModules: [
    // Simple usage
    "@kalligator/nuxtjs-localforage",

    // With options
    [
      "@kalligator/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: ["@kalligator/nuxtjs-localforage"],
  localforage: {
    /* module options */
  },
};

Options

driver (optional)

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

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

name (optional)

• Default: 'nuxtJS'

The name of the database. May appear during storage limit prompts. Useful to use the name of your app here. In localStorage, this is used as a key prefix for all keys stored in localStorage.

size (optional)

• Default: 4980736

The size of the database in bytes. Used only in WebSQL for now.

• Default: 'nuxtLocalForage'

The name of the datastore. In IndexedDB this is the dataStore, in WebSQL this is the name of the key/value table in the database. Must be alphanumeric, with underscores. Any non-alphanumeric characters will be converted to underscores.

A description of the database, essentially for developer usage.

Gets the length

let length = await this.$localForage.length;

Get the name of a key based on its ID

let keys = await this.$localForage.keys();

Force usage of a particular driver or drivers, if available

this.$localForage.setDriver(localforage.LOCALSTORAGE);

By default, localForage selects backend drivers for the datastore in this order:

1. IndexedDB
2. WebSQL
3. localStorage

If you would like to force usage of a particular driver you can use $setStorageDriver() with one or more of the following parameters.

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

Advanced Usage

You can register multiple instances, see below:

// nuxt.config.js
export default {
  buildModules: ["@kalligator/nuxtjs-localforage"],

  localforage: {
    instances: [
      {
        name: "myApp",
        storeName: "images",
      },
      {
        name: "myApp",
        storeName: "fileSystem",
      },
    ],
  },
};

// for images
await this.$localforage.images.setItem(key, value);

// for fileSystem
