Here's how: - -### The Problem - -If you have deferred Redux stores and components like this: - -```erb -<% redux_store("SimpleStore", props: @app_props_server_render, defer: true) %> -<%= react_component('ReduxApp', {}, {prerender: true}) %> -<%= react_component('ComponentWithNoStore', {}, {prerender: true}) %> -<%= redux_store_hydration_data %> -``` - -By default, React on Rails assumes components depend on all previously created stores. This means: - -- Neither `ReduxApp` nor `ComponentWithNoStore` will hydrate until `SimpleStore` is hydrated -- Since the store is deferred to the end of the page, both components are forced to wait unnecessarily - -### The Solution - -Explicitly declare store dependencies for each component: - -```erb -<% redux_store("SimpleStore", props: @app_props_server_render, defer: true) %> -<%= react_component('ReduxApp', {}, { - prerender: true - # No need to specify store_dependencies: it automatically depends on SimpleStore -}) %> -<%= react_component('ComponentWithNoStore', {}, { - prerender: true, - # Explicitly declare no store dependencies - store_dependencies: [] -}) %> -<%= redux_store_hydration_data %> -``` - -This allows `ComponentWithNoStore` to hydrate immediately without waiting for `SimpleStore`, improving page performance. +See [React on Rails 16.0.0 Release Notes](./16.0.0.md) for the latest version. \ No newline at end of file From 6ada211a0396508c0b1ee39ca9e1e219be858be7 Mon Sep 17 00:00:00 2001 From: Justin Gordon Date: Mon, 15 Sep 2025 15:10:27 -1000 Subject: [PATCH 13/16] Update Gemfile.lock to use version 15.0.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Gemfile.lock was incorrectly referencing version 16.0.0 after reverting the version.rb back to 15.0.0.
