Bump react_on_rails from 16.1.1 to 16.2.1

[dependabot]

Bumps react_on_rails from 16.1.1 to 16.2.1.

Changelog

Sourced from react_on_rails's changelog.

[16.2.1] - 2026-01-18

Fixed

• bin/dev Route Argument Parsing: Fixed bin/dev command failing with "Unknown argument: hello_world" when run without arguments. The --route argument format was changed from two separate arguments to a single combined argument (--route=value). PR 2309 by K4sku.

Developer (Contributors Only)

• Benchmarking in CI: A benchmark workflow will now run on all pushes to master, as well as PRs with benchmark or full-ci labels. PR 1868 by alexeyr-ci2.

[16.2.0] - 2026-01-14

Breaking Changes

• config.immediate_hydration configuration removed: The config.immediate_hydration setting in config/initializers/react_on_rails.rb has been removed. Immediate hydration is now automatically enabled for React on Rails Pro users and automatically disabled for non-Pro users.

  Migration steps:

  • Remove any config.immediate_hydration = true or config.immediate_hydration = false lines from your config/initializers/react_on_rails.rb file
  • Pro users: No action needed - immediate hydration is now enabled automatically for optimal performance
  • Non-Pro users: No action needed - standard hydration behavior continues to work as before
  • Component-level overrides: You can still override behavior per-component using react_component("MyComponent", immediate_hydration: false) or redux_store("MyStore", immediate_hydration: true)
  • If a non-Pro user explicitly sets immediate_hydration: true on a component or store, a warning will be logged and it will be enforced to fall back to standard hydration (the value will be overridden to false)

  PR 1997 by AbanoubGhadban.

• React on Rails Core Package: Several Pro-only methods have been removed from the core package and are now exclusively available in the react-on-rails-pro package. If you're using any of the following methods, you'll need to migrate to React on Rails Pro:

  • getOrWaitForComponent()
  • getOrWaitForStore()
  • getOrWaitForStoreGenerator()
  • reactOnRailsStoreLoaded()
  • streamServerRenderedReactComponent()
  • serverRenderRSCReactComponent()

Migration Guide:

To migrate to React on Rails Pro:

1. Install the Pro package:

   yarn add react-on-rails-pro
   # or
   npm install react-on-rails-pro

2. Update your imports from react-on-rails to react-on-rails-pro:

   // Before
   import ReactOnRails from 'react-on-rails';
