[justin808]

Overview

Create a new Rails 8 application with React on Rails Pro configured for RSC support.

Parent Epic: #70
Priority: P0

Prerequisites

None - this is the starting issue.

Next Issues (after this is complete)

• 1.2: Configure CSS Modules
• 1.3: Set Up TypeScript Configuration
• 2.1: Create Hacker News API Client

Acceptance Criteria

• New Rails 8 app created in demos/hn-rsc/
• React on Rails Pro gem installed and configured
• RSC support enabled in react_on_rails configuration
• Basic Vite/Rspack configuration for RSC
• Application boots successfully with bin/dev

Implementation Notes

• Use Rspack for faster build times (matching other demos in this repo)

spec/dummy/spec/system/integration_spec.rb: ## AI-generated summary of changes

The diff introduces a new test suite for a TurboStream component within the integration tests located in spec/dummy/spec/system/integration_spec.rb. It adds a describe block specifically for testing the immediate loading of the "hello-world" component. The test case, titled "force load hello-world component immediately," simulates user interaction by visiting a designated page and clicking a button to trigger the loading of the TurboStream component. The expectation checks for the presence of a specific text on the page, confirming the successful rendering of the component. This addition enhances the test coverage for TurboStream functionality, ensuring that the component behaves as intended when invoked.

AI-generated summary of changes

Adds a new ReScript-generated React component at client/app/bundles/comments/rescript/RescriptShow/ror_components/RescriptShow.jsx. Implements a reducer that returns FetchError when action is not an object, otherwise yields CommentsFetched with the action payload. Introduces ReScriptShow$default using useReducer with initial state commentsFetchStatus as CommentsFetched([]). Adds fetchData to fetch comments via Actions.Fetch.fetchComments, dispatching SetComments on Ok or SetFetchError otherwise. Subscribes to a CommentsChannel via ActionCable, handling connected, received (dispatching SetComments with the incoming data wrapped in an array), and disconnected. Uses two useEffect hooks: one for channel subscription lifecycle, one to trigger fetchData on mount. Renders a header area with a react_on_rails link, a “Comments” section, a CommentForm wired to fetchData, and either an AlertError or CommentList depending on fetch state. Exports reducer as a named export and default as ReScriptShow$default (aliased to default export).

AI-generated summary of changes

• Replaces the previous runtime logic (checking for external process managers and launching via system calls) with a static-assets focus by loading development tooling directly and invoking the static-mode server path.
• Removes installed?-based checks and error prompts for overmind/foreman; drops Procfile.dev-static launch flow.
• Introduces a safe fallback: attempts to require bundler/setup and react_on_rails/dev, and on LoadError, loads a local dev helper via require_relative.
• Forces static mode by invoking ReactOnRails::Dev::ServerManager.run_from_command_line(["static"]) instead of selecting a process manager.
• Adds initial explanatory comments about static assets mode and the rationale for static assets usage.

AI-generated summary of changes

• Adds YAML syntax error handling in load_dependencies when a custom dependencies config exists, including user-facing error messages and exit(1) on parse failure.
• Introduces several RuboCop disable/enable pragmas around load_dependencies, install_dependencies, and switch_to to accommodate complexity in these methods.
• Inserts an empty line output (puts "") before dependency management messaging in install_dependencies, and aligns removal/uninstallation messaging to display both dev and prod uninstall commands in both branches.
• In the not-automatically-install branch of install_dependencies, ensures uninstall commands for both dev and prod dependencies are printed in the webpack branch and prints them in the rspack branch as well.
• In the rspack path of the install flow, adds a cleanup sequence (removing node_modules and package-lock.json, followed by a clean npm install) when bundler is rspack.

New Cypress support file demos/basic-v16-webpack/e2e/playwright/support/index.js added. This file is processed and loaded automatically before test files, and it serves as a global configuration surface for Cypress behaviors. It imports a module at ./on-rails (import syntax) and contains commented-out alternatives for including commands (CommonJS and other Cypress support options). The active portion ensures an initialization step by importing the on-rails integration; the rest are instructional comments about configuration and alternative import methods.

demos/basic-v16-webpack/e2e/playwright/support/on-rails.js:
"""

AI-generated summary of changes

Introduces a new Playwright-based support module on-rails.js that centralizes e2e server interactions via a pre-initialized request context. Key functionality:

• Establishes a shared request context with a base URL derived from Playwright config (fallback to localhost:5017).
• Exposes appCommands(data) to POST to /e2e/command and return the first element of the response body after asserting success.
• Provides small wrappers: app(name, options), appScenario(name, options), appEval(code), appFactories(options) to invoke various e2e commands through appCommands.
• Adds VCR cassette control: appVcrInsertCassette(cassette_name, options) to insert a cassette with optional options (filters undefined values) and returns response body after asserting success; appVcrEjectCassette() to eject the cassette with success assertion.
• All exported functions perform a POST request to the corresponding endpoints, assert response.ok(), and return the parsed response body as needed.

Public exports now include: appCommands, app, appScenario, appEval, appFactories, appVcrInsertCassette, appVcrEjectCassette.

demos/basic-v16-webpack/lefthook.yml:
"""

AI-generated summary of changes

Adds a Lefthook configuration file for React on Rails demos, defining pre-commit, pre-push, and commit-msg hooks. Pre-commit runs rubocop (backend), eslint (frontend), and prettier (frontend) on staged Ruby/JS/TS/JSON/CSS/SCSS/MD files with appropriate glob patterns and writes formatting changes. Pre-push runs full checks: rubocop-all, eslint-all, tests (rails, rspec, jest) with skips for merge/rebase where applicable, and bundle-audit for security with ignore flag. commit-msg invokes commitlint via npx if available, to validate commit messages. The configuration enables parallel execution for hooks and connects each command with tags indicating the area (backend/frontend/style/tests/security).
