This is the second post of a series of articles about how the several technologies conforming the New Gaia Architecture (NGA) fit together to speed the Web.
In the first chapter, we focused on performance and resource efficiency and we realised the potential conflict between the multi-page approach to web applications where each view is isolated in its own (no iframe) document and the need for keeping in memory all the essential logic & data to avoid unnecessary delays and meet the time constrains for an optimal user experience.
In this chapter I will explore web workers in its several flavours: dedicated workers, shared workers and service workers and how they can be combined to beat some of these delays. As a reminder, here is the breakdown from the previous episode:
- Navigate to a new document.
- Download resources (which includes the template).
- Set your environment up (include loading shared libraries).
- Query your API for the model.
- Combine the template with your model.
- Render the content.

I spent most part of this year working in Service Workers for the New Gaia Architecture (NGA) that Mozilla is preparing to release with Firefox OS 2.5 & 3.0. This is the first of a series of articles about the effort we are putting in evolving Gaia while contributing to best programming practises for Modern Mobile Web.
More than an architecture, NGA is a set of recommendations to reach specific goals, good not only for Firefox OS applications but for any modern web application: offline availability, resource efficiency, performance and continuity. Different technologies exists (and other are coming) to help reaching each target.
Although, there is some confusion about how all these technologies fit together. Even inside the Firefox OS team some see pinning apps (which is a mechanism to keep and entire site cached forever and it must not to be confused with the concept of pinning the web) overlaps with Offline Cache. Other people see the render store unnecessary and overlapping with the prerender technology. If this is your case or simply you did not know about these concepts, continue reading, you deserve an explanation first.
