Usually, you'll want to go with the default way, using in-line keys. This is a feature of IndexedDB, and it means that an object's identifier is not kept on the object itself. IDBWrapper supports working with out-of-line keys. Parameter and inside of the options object, the function passed as second Receives the error instance as only argument.Īs an alternative to passing a ready handler as second argument, you can also OnError gets called if an error occurred while trying to open the store. ImplementationPreference is an array of strings containing the implementations to check for availability. Indexes is an array of objects defining indexes (see the Indexes page for details). YouĬan leave it to true, even if you do provide your own ids. If you want to use out-of-line keys, you must set this property to null (see below for details on out-of-line keys).ĪutoIncrement is a boolean and toggles, well, auto-increment on or off. The database will automatically add a unique key to the keyPath index when storing objects missing KeyPath is the name of the property to be used as key index. This if you change the structure of the store at a later time. You want to have full control over the IDB name, you can pass your own prefix.ĭbVersion is the version number of your store. You can safely ignore this property, but if StorePrefix is an additional prefix the created database will finally have StoreName is the name of the store: for different stores, use different names. The options object may contain the following properties (default values are shown - all The second is a function reference to a function that is called when the store is ready to use. You may pass two parameters to the constructor: the first is an object with optional parameters, You can then create an IDB store: var myStore = new IDBStore()

(the constructor will then, of course, have whatever name you call it).

To load the module, and you will receive the constructor in your load callback Including the idbstore.js file will add an IDBStore constructor to the global scope.Īlternatively, you can use an AMD loader such as RequireJS, or a CommonJS loader
