Getting Started with IndexedDB for Big Data Storage

This example code uses a client-side IndexedDB database to store page and resource performance metrics which can be analysed and uploaded later.

Usage

Copy the files to a web server (http://localhost:8888 is presumed) and open the index.html file in a browser. Open DevTools to view the calculated statistics.

The filename variable on line 77 of js/performance.js will need to be changed if you use a different domain, port, or path.

The following files are provided:

1. js/indexeddb.js a wrapper API for IndexedDB database functionality, and
2. js/performance.js a file which uses the wrapper API to store performance data.
