This is an optional argument assuming you do not need to pass any options (if you want to pass options, such as `prerender: true`, but you do not want to pass any properties, simply pass an empty hash `{}`). **Props are automatically sanitized by React on Rails for security.** This will make the data available in your component: - -- This is what your HelloWorld.js file might contain.

- ); - }; - ``` - -## What Happens Next? - -The generator set up the following: - -1. Component directory: `app/javascript/bundles/HelloWorld` -2. Rails integration for rendering this component in a Rails view -3. Webpack configuration for building your JavaScript bundle - -![Basic Hello World Example](./images/bundle-splitting-hello-world.png) - -#### Different Server-Side Rendering Code (and a Server-Specific Bundle) - -You may want different code for your server-rendered components running on the server side versus the client side. For example, if you have an animation that runs when a component is displayed, you might need to turn that off when server rendering. One way to handle this is conditional code like `if (typeof window !== 'undefined') { doClientOnlyCode() }`. - -Another way is to use a separate Webpack configuration file that can use a different server-side entry file, like 'serverRegistration.js' as opposed to 'clientRegistration.js.' That would set up different code for server rendering. - -For details on techniques to use different code for client and server rendering, see: [How to use different versions of a file for client and server rendering](https://forum.shakacode.com/t/how-to-use-different-versions-of-a-file-for-client-and-server-rendering/1352). (_Requires creating a free account._) - -## Specifying Your React Components - -You have two ways to specify your React components. You can either register the React component (either function or class component) directly, or you can create a function that returns a React component, which we using the name of a "render-function". Creating a render-function allows you to: - -1. Access to the `railsContext`. See the [documentation for the railsContext](./core-concepts/render-functions-and-railscontext.md) in terms of why you might need it. You **need** a Render-Function to access the `railsContext`. -2. Use the passed-in props to initialize a redux store or set up `react-router`. -3. Return different components depending on what's in the props. - -Note, the return value of a **Render-Function** should be either a React Function or Class Component or an object representing server rendering results. - -**Do not return a React Element (JSX).** - -ReactOnRails will automatically detect a registered Render-Function by the fact that the function takes -more than 1 parameter. In other words, if you want the ability to provide a function that returns the -React component, then you need to specify at least a second parameter. This is the `railsContext`. -If you're not using this parameter, declare your function with the unused param: - -```js -const MyComponentGenerator = (props, _railsContext) => { - if (props.print) { - // This is a React FunctionComponent because it is wrapped in a function. - return () =>

{JSON.stringify(props)}

; - } -}; -``` - -Thus, there is no difference between registering a React Function Component or class Component versus a "Render-Function." Just call `ReactOnRails.register`. - -## react_component_hash for Render-Functions - -Another reason to use a Render-Function is that sometimes in server rendering, specifically with React Router, you need to return the result of calling ReactDOMServer.renderToString(element). You can do this by returning an object with the following shape: `{ renderedHtml, redirectLocation, error }`. Make sure you use this function with `react_component_hash`. - -For server rendering, if you wish to return multiple HTML strings from a Render-Function, you may return an Object from your Render-Function with a single top-level property of `renderedHtml`. Inside this Object, place a key called `componentHtml`, along with any other needed keys. An example scenario of this is when you are using side effects libraries like [React Helmet](https://github.com/nfl/react-helmet). Your Ruby code will get this Object as a Hash containing keys `componentHtml` and any other custom keys that you added: - -```js -{ - renderedHtml: { - componentHtml, - customKey1, - customKey2, - }, -} -``` - -For details on using react_component_hash with react-helmet, see [our react-helmet documentation](./building-features/react-helmet.md). - -## Error Handling - -- All errors from ReactOnRails will be of type ReactOnRails::Error. -- Prerendering (server rendering) errors get context information for HoneyBadger and Sentry for easier debugging. - -## I18n - -React on Rails provides an option for automatic conversions of Rails `*.yml` locale files into `*.json` or `*.js`. -See the [How to add I18n](./building-features/i18n.md) for a summary of adding I18n. - -## More Reading - -Depending on your goals, here's a progression of what to do next: - -1. **[View Helpers API](./api-reference/view-helpers-api.md)** - for more options of the `react_component` method. -2. **[Tutorial](./getting-started/tutorial.md)** - Comprehensive walkthrough of features with a real app. -3. **[Configuration](./api-reference/configuration.md)** - Details on every possible option you can configure. -4. **[Migration Guide](./upgrading/upgrading-react-on-rails.md)** - Upgrade advice for each version. - ---- - -## Additional Resources - -### Rails/React Integration Options - -- **[Rails + Webpack Comparison](./building-features/rails-webpacker-react-integration-options.md)** - -### JavaScript/TypeScript Module System - -- See the official [Shakapacker documentation](https://github.com/shakacode/shakapacker) for more details regarding this topic. diff --git a/docs/getting-started/quick-start.md b/docs/getting-started/quick-start.md index a17ca92b5..5d3e0defe 100644 --- a/docs/getting-started/quick-start.md +++ b/docs/getting-started/quick-start.md @@ -159,7 +159,7 @@ Now that you have React on Rails working, here's what to explore next: ### Immediate Next Steps -1. **[Basic Configuration](../getting-started.md)** - Understand the setup +1. **[Understanding React on Rails](./understanding-react-on-rails.md)** - Core concepts explained 2. **[View Helpers API](../api-reference/view-helpers-api.md)** - Learn all the options for `react_component` 3. **[Hot Module Replacement](../building-features/hmr-and-hot-reloading-with-the-webpack-dev-server.md)** - Optimize your dev workflow diff --git a/docs/getting-started/understanding-react-on-rails.md b/docs/getting-started/understanding-react-on-rails.md new file mode 100644 index 000000000..f516c7f3a --- /dev/null +++ b/docs/getting-started/understanding-react-on-rails.md @@ -0,0 +1,238 @@ +# Understanding React on Rails + +This guide explains the core concepts of React on Rails and how everything fits together.

From the Webpack documentation: - -> For big web apps it’s not efficient to put all code into a single file, especially if some blocks of code are only required under some circumstances. Webpack has a feature to split your codebase into “chunks” which are loaded on demand. Some other bundlers call them “layers”, “rollups”, or “fragments”. This feature is called “code splitting”. - -## Server Rendering and Code Splitting - -Let's say you're requesting a page that needs to fetch a code chunk from the server before it's able to render. If you do all your rendering on the client side, you don't have to do anything special. However, if the page is rendered on the server, you'll find that React will spit out the following error: - -> Warning: React attempted to reuse markup in a container but the checksum was invalid. This generally means that you are using server rendering and the markup generated on the server was not what the client was expecting. React injected new markup to compensate which works but you have lost many of the benefits of server rendering. Instead, figure out why the markup being generated is different on the client or server: - -> (client) `
