| How to update WRT widgets without installing a new version | Week 41 - October 4th 2009 |
This week's featured article, How to update WRT widgets without installing a new version, is written by Jappit.
Being able to update itself is one of the most important features an application can have. The mechanism can vary, but the goal is more or less the same: granting the application improved functionality as efficiently as possible.
This article describes an alternative to the classic widget update mechanism. Through a three step process, the widget requests and receives new JavaScript code, stores it locally and uses it in the subsequent sessions. This approach guarantees minimum effort requirement from the user and reduces the amount of transferred data ensuring the entire operation is performed in an efficient manner.
Read the article to gain insight into this very useful widget update technique.
