Put your extensions on a diet with event pages

Thursday, June 21, 2012

Event PagesHow They Work background pagesevent page documentation

The alarms API allows an extension to wake itself up at set times, to support features like periodically syncing data to the cloud.

Some new events let extensions know when they have been installed, or when their event page is being unloaded.

A declarative version of the webRequest API lets extensions do network interception without the need for a background page at all.

Inline installation for your apps and extensions

Monday, March 19, 2012

Chrome Web Storeinline installation

Chrome extensions Evernote Clearly and Evernote Web Clipper derive 15% and 25% of their Chrome installations (respectively) from their inline installation implementation

Rovio implemented inline installation for their Angry Birds Chrome game and saw their install rate jump by almost 10%)

Equire, a CRM extension that integrates with Gmail, saw a 66% increase in Chrome user retention after they implemented inline installation.

Example: Installing Evernote Web Clipper from Evernote’s Site

Provide a link to your Chrome Web Store item.
Write some script to check for whatever client-side capabilities your app requires (support for WebGL, the Web Audio API, etc). Modernizr is a great library to use for this.
Call a JavaScript function to initiate the install process.

The user sees the same Add To Chrome dialog prompt that they would on the store, confirm the install, and they're done – all without leaving your site.
The full details and documentation for using inline installation can be found here. If you have any questions, you can reach us on our developer forum.

International Success with the Chrome Web Store

Audiotool is an online music production app that was built by a team of German developers. They saw the Chrome Web Store as a way to present their app to an international audience. Audiotool’s traffic increased by 20% after launching in the store, and this motivated the team to release another app in the store.

Psykopaint is the brainchild of French developer Mathieu Gosselin. The Chrome Web Store provided Mathieu an opportunity to get his photo painting app noticed outside of France. Traffic to Psykopaint has jumped by 700% since it launched in the store and Mathieu has found that Chrome Web Store users tend to be more engaged than other users.

Finally, Nulab, a Japanese company, launched its online diagramming app, Cacoo, in the store to expand its user base outside Japan. In just a few months after Cacoo was released in multiple languages in the Chrome Web Store, the app already accounts for 20% of Cacoo’s user base.
