Open Source Resources for Web Application Developers

Solutoire took part of PlotKit and wrote some parts himself, then made Plotr which does not need the Mochikit library to work with. It is also a lightweight charting framework with only 12kb. There are more than 30 options for you to customize the chart. Like PlotKit, you can display Pie Charts, Line Charts and Bar/Column Charts.

Requirements: Firefox 1.5+, Safari 2.0+, Opera 9.0+, IE6+ (emulated)

Google Gears is an open source browser extension that enables web applications to provide offline functionality using JavaScript APIs. Due to the concern about internet security, building web application which store and serve sensitive information locally on users’ own computers are very useful.

• Store and serve application resources locally
• Store data locally in a fully-searchable relational database
• Run asynchronous Javascript to improve application responsiveness

It is a similar idea with Apollo which enable offline use of web applications. From now on, users can store data locally in their database on their own computer. So that some users can use the web application they like, at the same time prevent their sensitive information being hacked by storing their information locally.

Requirements: Windows XP / Vista, Internet Explorer 6.0+, Firefox 1.5+
