If you’re working on a Symfony project, Webpack Encore helps make handling your frontend assets (like JavaScript and CSS) easier. Here are the top 5 Webpack settings that can help improve your Symfony project.

1. CopyWebpackPlugin

The CopyWebpackPlugin is useful when you need to copy files like images, fonts, or icons from one folder to another without modifying them.

Example:

const CopyWebpackPlugin = require('copy-webpack-plugin');

Encore
    .addPlugin(new CopyWebpackPlugin({
        patterns: [
            { from: './assets/images', to: 'images' }
        ]
    }));

This will copy all the images from your assets/images folder to the public/build/images folder, making them available for use in your project.

2. splitEntryChunks()

splitEntryChunks() helps speed up your site by splitting large JavaScript files into smaller pieces. This way, the browser can load smaller files quicker.

Example:

Encore
    .splitEntryChunks();

This will break down big JavaScript files into smaller chunks, which will load faster for users.
