In Chrome the code works pretty well, however, in Microsoft Edge the brwoser windows remains blank white without any output. I have not modified the Create-React-Package in any way, however, this also holds true for apps that I wrote according to tutorials: Working great in Chrome, but Edge simply shows a white screen as if no code was executed at all.

That is by design. If you look in your package. You must be using some latest javascript functions like String. You can add polyfill.

If you look in the Developer Tools, you'll see any errors that are happening. If you supply them it will be easier to track down the issue. Learn more. Asked 2 months ago. Active 2 months ago.

Related You can import a file right in a JavaScript module. This tells webpack to include that file in the bundle. Unlike CSS imports, importing a file gives you a string value. This value is the final path you can reference in your code, e. To reduce the number of requests to the server, importing images that are less than 10, bytes returns a data URI instead of a path.

This applies to the following file extensions: bmp, gif, jpg, jpeg, and png. SVG files are excluded due to This ensures that when the project is built, webpack will correctly move the images into the build folder, and provide us with correct paths. If you make a typo or accidentally delete an important file, you will see a compilation error, like when you import a non-existent JavaScript module.

The final filenames in the compiled bundle are generated by webpack from content hashes. It is not required for React but many people enjoy it and React Native uses a similar mechanism for images. One way to add SVG files was described in the section above. You can also import SVGs directly as React components. You can use either of the two approaches. In your code it would look like this:. This is handy if you don't want to load SVG as a separate file. Don't forget the curly braces in the import!

Use this prop to add an accessible title to your svg component. Docs Help GitHub. Create React App. With webpack, using static assets like images and fonts works similarly to CSS.

In addition to ES6 syntax features, it also supports:. Learn more about different proposal stages. While we recommend using experimental proposals with some caution, Facebook heavily uses these features in the product code, so we intend to provide codemods if any of these proposals change in the future. Note that this project includes no polyfills by default. By default, the generated project includes a browserslist configuration in your package.

The browserslist configuration controls the outputted JavaScript so that the emitted code will be compatible with the browsers specified. The production list will be used when creating a production build by running the build script, and the development list will be used when running the start script.

Note that this does not include polyfills automatically for you. You will still need to polyfill language features see above as needed based on the browsers you are supporting. When editing the browserslist config, you may notice that your changes don't get picked up right away. This is due to an issue in babel-loader not detecting the change in your package.

Previous article. Add React to a Website.This bundle can then be included on a webpage to load an entire app at once. For example, see the Installation and Getting Started guides on the Webpack docs. Bundling is great, but as your app grows, your bundle will grow too.

Especially if you are including large third-party libraries. Code-Splitting is a feature supported by bundlers like WebpackRollup and Browserify via factor-bundle which can create multiple bundles that can be dynamically loaded at runtime. The best way to introduce code-splitting into your app is through the dynamic import syntax. When Webpack comes across this syntax, it automatically starts code-splitting your app.

Your Webpack config should look vaguely like this. For that you will need babel-plugin-syntax-dynamic-import. If you want to do code-splitting in a server rendered app, we recommend Loadable Components. It has a nice guide for bundle splitting with server-side rendering. The React. This will automatically load the bundle containing the OtherComponent when this component is first rendered. This must return a Promise which resolves to a module with a default export containing a React component.

The fallback prop accepts any React elements that you want to render while waiting for the component to load. You can place the Suspense component anywhere above the lazy component. You can even wrap multiple lazy components with a single Suspense component. If the other module fails to load for example, due to network failureit will trigger an error. You can handle these errors to show a nice user experience and manage recovery with Error Boundaries.

Deciding where in your app to introduce code splitting can be a bit tricky. A good place to start is with routes.

Stack Overflow works best with JavaScript enabled.React has been designed from the start for gradual adoption, and you can use as little or as much React as you need. React components are a great way to do that.

With a few lines of code and no build toolingtry React in a small part of your website. You can then either gradually expand its presence, or keep it contained to a few dynamic widgets. You can follow along with your own website, or create an empty HTML file to practice. There will be no complicated tools or install requirements — to complete this section, you only need an internet connection, and a minute of your time.

Optional: Download the full example 2KB zipped. First, open the HTML page you want to edit.

For example:. This will allow us to find it from the JavaScript code later and display a React component inside of it. You may have as many independent DOM containers on one page as you need. They are usually empty — React will replace any existing content inside DOM containers. Open this starter code and paste it into the file you created. This code defines a React component called LikeButton. There is no step four.

You have just added the first React component to your website. View the full example source code. Download the full example 2KB zipped. This strategy is mostly useful while React-powered parts of the page are isolated from each other.

Before deploying your website to production, be mindful that unminified JavaScript can significantly slow down the page for your users. If you already minify the application scripts, your site will be production-ready if you ensure that the deployed HTML loads the versions of React ending in production. In the examples above, we only relied on features that are natively supported by the browsers.

This is why we used a JavaScript function call to tell React what to display:. However, React also offers an option to use JSX instead:. These two code snippets are equivalent. While JSX is completely optionalmany people find it helpful for writing UI code — both with React and with other libraries. You can play with JSX using this online converter.

This approach is fine for learning and creating simple demos. The only requirement is to have Node. Perform it in the same folder, and then try again. When you edit the source file with JSX, the transform will re-run automatically. As a bonus, this also lets you use modern JavaScript syntax features like classes without worrying about breaking older browsers. The tool we just used is called Babel, and you can learn more about it from its documentation.
