[![Build Status](https://travis-ci.org/drecom/idb-cache.svg?branch=master)](https://travis-ci.org/drecom/idb-cache)
[![npm version](https://badge.fury.io/js/%40drecom%2Fidb-cache.svg)](https://badge.fury.io/js/%40drecom%2Fidb-cache)
[![license](https://img.shields.io/github/license/drecom/idb-cache.svg)](LICENSE)

idb-cache is a fast and simple cache library for JavaScript using IndexedDB.

IndexedDB is persistent storage, but idb-cache automatically destroys old files. Therefore, users do not have to worry about storage pressure due to garbage files.

# Usage

## Initialization

```
const idbc = new IDBCache('examplesDB', {
  size : 52428800, // Size limit (Default 50MB)
  count : 100, // Number of files limit (Default 100)
  defaultAge : 86400, // max-age when there is no setting (Default 1day)
});
```

## Set cache

```
// Designate max-age
idbc.set('key1', 'value1'); // defaultAge cache
idbc.set('key2', 'value2', 604800); // 1week cache

// Supported type
idbc.set('key3', new ArrayBuffer(512)); // ArrayBuffer
idbc.set('key4', new Blob([new ArrayBuffer(1024)])); // Blob
```

## Get cache

```
idbc.get('key1').then(function(value){
  console.log(value);
}).catch(function(){
  // Does not exist, expired or error
});
```

# Target

idb-cache is focused on support of the following browsers.

 - Chrome for Android
 - iOS Safari (Support from v10)
