webpack follows this order when bundling the CSS files:.It is essential to note that the array of use : in the CSS area needs to be written in that exact order.exclude is where we state files to be ignored by the bundler.test states the file extension that needs to be targeted by the specific loader.module is where we pass the rules for bundling files.hot triggers a full page reload when we change any file in our application.We use port to set a port that the development server would run on.devServer is used as a development server.And filename is the name we set for the new bundled file created after webpack bundles all the JavaScript code.We named this folder dist, an industry standard. path states the name of the directory created, which will store all the bundled files.In the output, we state where to send the files when bundled.We also import the HTML-webpack-plugin, which simplifies the creation of HTML files to serve our webpack bundles. First, we import the path module from nodejs.This file will transpile react code from jsx to regular js. babelrc in the root directory of our app and add the following presets. We will now create a new file and name it. Always use the alt attribute to describe images, enhancing accessibility.Īfter successfully setting up the dependencies and devDependencies, we have to set up Babel and webpack to bundle our app and loading assets, respectively. Accessibility: Never forget the visually impaired.Use the srcSet attribute to handle this efficiently. Responsive Images with srcSet: In today’s age of multiple devices, it’s crucial to serve the right image size to the right device.CDNs cache content across global servers, ensuring faster delivery times. Content Delivery Network (CDN): If your React application is expected to have a wide user base, consider serving your images via a CDN.This ensures images load only when in the viewport, enhancing the initial page load time. Utilize the loading=“lazy” attribute on image tags. Lazy Loading: Always remember to incorporate lazy loading for images.It ensures your starting point already involves optimized assets. Third-party Compression Tools: Before even beginning with webpack, consider using tools like TinyPNG or JPEGmini to compress your images.In this post, we’d be looking at how to effectively optimize images in our reactjs applications using the image-webpack-loader module.īefore diving into the webpack specifics, it’s essential to note some fundamental best practices when handling images in web applications: As much as images are important elements of a good and appealing web application, they can also negatively impact its speed and user experience if handled poorly. Most web applications in the world have at least one picture. Images are an integral part of any web application.
