BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default 是指在webpack版本小于5的情况下,默认情况下会包含Node.js核心模块的polyfills。但是在webpack5中,移除了对Node.js核心模块的polyfill自动引入,所以需要手动引入node-polyfill-webpack-plugin来解决这个问题。您可以通过安装npm包node-polyfill-webpack-plugin,并将以下内容添加到您的webpack.config.js文件中来使用该插件:
```
const NodePolyfillPlugin = require("node-polyfill-webpack-plugin");
module.exports = {
// 其他配置项...
plugins: [
new NodePolyfillPlugin()
]
};
```

webpack < 5 used to include polyfills for node.js core modules by default
Yes, that's correct. In versions of webpack before 5, it used to include polyfills for Node.js core modules by default. This means that when bundling your code for the browser, webpack would automatically include polyfills for modules such as `fs`, `path`, `crypto`, and others, which are common in Node.js but not available in the browser environment.
Including these polyfills allowed developers to write code that used Node.js core modules without worrying about compatibility issues when running the code in the browser. However, this approach also added unnecessary code to the final bundle, increasing its size.
Starting from webpack 5, the default behavior has changed. Webpack no longer includes polyfills for Node.js core modules by default. Instead, it encourages developers to use conditional imports or other techniques to handle the use of these modules in a browser-compatible way.
This change was made to improve performance and reduce bundle size, as including unnecessary polyfills can have a negative impact on both. However, if you still need to include polyfills for Node.js core modules in your webpack 5 configuration, you can do so using plugins or other customizations.
webpack < 5 used to include polyfills for node.js core modules by default
Yes, that is correct. Prior to version 5, webpack had a feature called the "Node.js Polyfills" which included polyfills for Node.js core modules such as `path`, `fs`, and `util`. These polyfills allowed developers to use these modules in the browser without having to worry about compatibility issues. However, starting from version 5, webpack no longer includes these polyfills by default and requires them to be explicitly imported or provided by the user.
