minidb

A simple wrapper for the local/session storage DOM API management

The API is now compatible to Internet Explorer 6~8

NOTE: If you do not need to worry about old browsers support, simply take off the polyfills from the script.

NOTE2: When using older browsers remember to import JSON api from https://github.com/douglascrockford/JSON-js

How to use it

minidb.STORAGE_TYPE.ACTION

Where...

• STORAGE_TYPE = local or session
• ACTION
• selectAll/all
• select/get
• insert/set
• remove/del
• size/length

Examples:

minidb.local.set('name', 'Willian');

minidb.local.get('name'); //gives you "Willian"

minidb.session.set('userData', {id:333, name: 'Joseph'});

minidb.local.get('userData'); //gives you nothing

minidb.session.get('userData'); //gives you {id:333, name: 'Joseph'}

minidb.local.insert('someArray', [2, 3, 4, 5, 6, 'a string', {myObj: 'yay! an object'}]);

var someArray = minidb.local.select('someArray');

selectAll / all returns a key/value set of data.

If you do prefer an array instead of a set simply use minidb.local.all().toArray();

Lists

As of November 19 commit, the method toArray from the all() method has been set as not enumerable. So, when you do a for(var k in minidb.local.all()) ... the toArray method is not displayed anymore.

This change may cause the method to not be created in older browsers. In case you are using older browsers, toArray can be accessed directly as follows:

minidb.local.toArray()

Alternatively, you can use:

minidb.local.list()
