Served with FastBoot (again)

By: Dan McClain

A little less than a year ago, we launched the redesigned, which at launch was running an early version of FastBoot. And by early version, I mean alpha version, when Ember had some memory leaks, which caused FastBoot to crash. Since then, was a FastBoot Rendered, Statically Served™ site. I would run a local instance of FastBoot, use a custom crawler to crawl everything but the blog and save static files of the site. I would then push those static files to the server and let Nginx serve the files. This gained us the benefits of running FastBoot (except on the blog), without FastBoot running and crashing because of the memory leaks. The reason that the blog was left out was because of the fact that using {{{blog.body}}} was not rendered in that version of FastBoot, leaving the post content of every blog post out of the page source.

FastBoot keeps moving

As time went on, the memory leaks in Ember were fixed, and FastBoot has been continually developed. Ember has also been updated so that stable releases, as of 2.3.0, support FastBoot. Previously you had to use the canary version and enable a feature flag to allow Ember to work with Fastboot.

And recently, I revisited the DockYard site and worked to reimplement FastBoot. In terms of work on, there was little to no work, we had previously submitted pull requests to addons we were using to make them FastBoot compatible. Most of the recent work was around contributing to FastBoot to help make it easier for applications to drop in.

There have been many contributors to FastBoot, helping to make it a reality. Ember Data, as of 2.4.0, works with FastBoot with little configuration (you need to provide the host to your adapter for now, as relative URLs do not work for FastBoot's AJAX layer). There is a FastBoot service available to your Ember app that gives you access to cookies, headers and the requested host in the FastBoot version of your application. may be a bit on the bleeding edge, but a production version of FastBoot is not that far off.
