IndexedDB preference storing

Simplified preference storing

Install

From NPM:

npm install indexeddb-preference-storing --save

Or download the index.js file.

Usage

Firstly, request opening the database with plain IndexedDB.

const dbOpenRequest = indexedDB.open('test-preference-storing');```

Then send that to storePreferences. It returns a Promise, which resolves when the database is opened. The resolve function has one parameter, what can be used to set & get preferences.

storePreferences(dbOpenRequest).then(preferences => {/* set & get preferences */});

• Setting preference: preferences.set('preferenceName','preferenceValue')
• Getting preference: preferences.get('preferenceName') - returns a Promise what resolves when it successfully gets the preference. The value of the preference is in the first parameter. If the preference doesn't exist, it's value is undefined.

An example can be found in example.html.

Warning: the library uses the prefrences object store in the requested database.
