Class: Everywhere::MobileConfigsController

Inherits:
ActionController::API

Defined in:
lib/everywhere/mobile_configs_controller.rb

Overview

Serves the mobile shells' remote path configuration in Rails apps:

GET /everywhere/ios_v1.json      -> MobileConfigsController#show

The route is appended by Everywhere::Engine, so it shows up in rails routes and the app can override it by drawing its own. Inherits ActionController::API on purpose:

* never the app's ApplicationController — its before_actions
(authentication!) would lock the shells out, and
* not ActionController::Base — its `helper :all` resolution reaches
into the host app's helpers, which aren't loadable when the gem is
required during boot. A JSON endpoint needs none of that.

everywhere.yml is re-read on every request: tab changes go live with a deploy — or a plain file save in development, where responses are explicitly uncached so the dev shell's reload polling sees them instantly.

Instance Method Details

#reset ⇒ Object

GET /everywhere/reset?to=/path — the native "reset the app" page. Auth flows redirect the shell here so it rebuilds cleanly before landing on to. Never cached (it must run every time).

def show
  config = Config.load(::Rails.root.to_s)

  # Never cache: the response depends on the session (filter_tabs can hide
  # tabs when signed out), so a shared/public cache could serve one user's
  # tabs to another, and a client cache would serve stale tabs across
  # sign-in/out. The endpoint is a couple of milliseconds — no cache needed.
