Rails Meets React.js Pdf Download

This book is really awesome! I want to thank you for such brilliant work, that helped me to understand React concepts, especially from rails point of view. I believe, frontend development will not be so painful anymore!
I think eventually I will either move JS testing before assets pre-compilation and rails testing. Alternatively, I am going to split this one long job into a workflow with two separate jobs. Especially considering that 90% of commands (some not listed for clarity) do not affect JS testing at all.
I want to import this react-infinite-scroller react library in a rails project but meet some problems. After I installed it, I could not import it using import InfiniteScroll from 'react-infinite-scroller'; or var InfiniteScroll = require('react-infinite-scroller')['default']; in application.js. There would be a SyntaxError: unterminated string literal for the first one and ReferenceError: require is not defined for the second one.

Intro Rails 7 brought with it an overhaul of the Asset Pipeline in the form of multiple new gems that either introduced a new way of handling assets (importmaps-rails), or broke down existing gems (propshaft, jsbundling-rails, cssbundling-rails)...
One of the problems with esbuild is it doesn't come with glob imports out of the box, so we need to add a plugin for that called esbuild-plugin-import-glob. We'll also install a bunch of npm packages that react-rails tells us to:
In the Server Rendering section of the react-rails readme you'll see that adding prerender: true in the third argument to react_component should render the component server side. I though, cool, I'll try creating a mailer template that renders a react_component built from the react.email tools:
Recall that we changed the entry point for application js? The server_rendering.js file that comes with react-rails wont work with esbuild, so we had to modify it to use our custom glob import thing like this:
Turbo Streams are a great match-up for Action Cable as it makes it easy to broadcast DOM updates to the browser over WebSockets. The turbo-rails gem integrates with Action Cable to facilitate such updates.
turbo-rails contains a JavaScript custom element which encapsulates the logic to create an Action Cable connection, subscribe to a channel and execute received Turbo Streams. On the server-side, it provides a default channel and a plethora of helper methods to broadcast data based on models.
turbo-rails has a default channel called Turbo::StreamsChannel to handle broadcasts and subscriptions. We briefly encountered it while discussing the broadcast helpers. It verifies the signed stream name and subscribes the client to the appropriate stream.
That's the Turbo Streams integration with Action Cable in a nutshell. It packs in immense power with relatively little code. The docs for turbo-rails are sparse at best, but I recommend keeping the YARD docs handy for reference: -rails.
