@converse/localforage-getitems

This is a fork of localforage-getitems which adds support for the getAll
function for IndexedDB.

The upstream pull request is here: https://github.com/localForage/localForage-getItems/pull/12

The upstream project appears to be unmaintained and hasn't had any changes in 5
years.

Requirements

* localForage v1.4.0+
* for earlier versions of localforage, please use the v1.1.x releases

Installation

npm i @converse/localforage-getitems

jsperf links

* default driver order (indexedDB prefered)
* websql (not for firefox)

API

Just like getItem() but you can pass an array with the keys that need to be retrieved.

``javascript
const keys = ['asdf','asap','async'];

localforage.getItems(keys).then((results) => {
console.log(results);
// prints:
// {
// asdf: 'asdf value!',
// asap: 'asap value!',
// async: 'async value!'
// }

console.log(results.asdf);
console.log(results['asdf']);
console.log(results[keys[0]]);
// all the above print 'asdf value!'
});
`

Invoking getItems() without arguments (or with null as the first argument) will retrieve all the items of the current driver instance.

`javascript
localforage.getItems().then((results) => { });

// or by using callbacks
localforage.getItems(null, results) => { });
