jf-storage 0.0.1 


Several classes and polyfills implementing Web Storage API.

You can store item in memory, cookies, files, browser storage, etc. Also, you can encrypt/decrypt data
in storage using jf.storage.serializer classes, and obfuscate keys using key builders.

Proxy

jf.storage.Proxy it's a proxy to other storages but allow us to do advanced things
adding some behaviors through injection dependency.

$3

We want store data requested to servers with following requirements:

- Store data in files.
- Data in files must be stored using JSON format.
- Filename must be first 6 chars in MD5 hash of URLs.
If data is read from http://joaquinfernandez.net/api/users/1, filename will be 05fdf4.json

``javascript
const jfStorageFile = require('jf-storage-api/src/File');
const jfStorageKeyCrypto = require('jf-storage-api/src/key/Crypto');
const jfStorageProxy = require('jf-storage-api/src/Proxy');
const jfStorageSerializerJson = require('jf-storage-api/src/serializer/Json');

function doRequest(url)
{
return {
firstname : 'Homer',
lastname : 'Simpson'
};
}

const storage = new jfStorageProxy(
{
key : new jfStorageKeyCrypto('md5', 6),
serializer : new jfStorageSerializerJson(),
storage : new jfStorageFile('/path/to/cache/directory', '.json')
}
);

// Read data from server.
const url = 'http://joaquinfernandez.net/api/users/1';
const response = doRequest(url);
// Store in cache.
storage.setItem(url, response);

//...
//...
//...

// Retrieve data:
const data = storage.getItem(url);
console.log(data); // { firstname : 'Homer', lastname : 'Simpson' }
`

Response will be stored in /path/to/cache/directory/05fdf4.json`.
