local first

 local first  is a UX design method for installed applications (including webapps with service workers) that enables the user to make use of some or preferably all of their features without requiring any non-local (like network) interactions or connections, typically to at least view, create, edit, and save content which may at a later time be published to the web or synchronized to another device perhaps across a network.

 * Traditional native installed email applications (e.g. Thunderbird)

Local-first ideals include the ability to work offline and collaborate across multiple devices, while also improving the security, privacy, long-term preservation, and user control of data.""Seven ideals for local-first softwareNo spinners: your work at your fingertipsYour work is not trapped on one deviceThe network is optionalSeamless collaboration with your colleaguesThe Long NowSecurity and privacy by defaultYou retain ultimate ownership and control"

First means first
Local first literally means once you’ve installed the app (e.g. loaded the web page), there is nothing else you have to do first in order to use its features involving local UI / content creation and editing, including, no requirement to sync-up or sign-in to a server, or create an account first, or any other kind of "set up" that requires network access, because that would make it local second to such requirements.

No account required
For counter-example, the Quip iOS app has an option when launching it to "Skip Creating an Account", however, if you choose that when offline (e.g. airplane mode), then you get the following error:



<blockquote style="text-align:center; width:18em">Sign In Error We encountered an error signing you in to Quip. There may be a problem with your network connection, or there may be a temporary error with the service.

When of course, skipping creating an account should not require signing in to Quip, or a network connection, or a "service" at all!

Blog that loads recent posts
One example of a (at least partial) local first IndieWeb "app" could be a personal site that when the home page is loaded, uses offline first techniques to proactively load the information necessary to render recent post permalinks, without ever having loaded those pages directly from the server.
 * undefined is considering implementing this (describing here in case others can use some of these techniques, rather than only on Falcon page)
 * load the past year’s bim files via offline first techniques
 * implement client-side rendering of those bim files via a fully CASSIS implementation of Falcon rendering code
 * use service worker to detect when a permalink is being accessed whose storage file has been cached, and call that client-side rendering code instead
 * challenge: cache invalidation, i.e. when to "reload" older bim files (most recent bim storage file should be loaded whenever online via offline first techniques) that may have minor fixes/updates.
