How do I set up hot reload in Vue.js?

To set up hot reload in Vue.js, you need to ensure you're using Vue CLI. When you create a new project with Vue CLI, hot reloading is enabled by default.

What if I didn't use Vue CLI? Can I still enable hot reload?

Yes, you can enable hot reload manually by configuring Webpack. You'll need to set up the webpack-dev-server and include the HotModuleReplacementPlugin.

Can you show me an example of the Webpack configuration?

Sure! Here's a basic example:

const webpack = require('webpack');
module.exports = {
  // other configurations...
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
  ],
};

Is there anything else I need to do after setting up the configuration?

Make sure to run your development server with the --hot flag to enable hot module replacement.
