html-webpack-plugin VS terser-webpack-plugin

now we have a dist directory. inside of dist we have main.js file, to execute the file in browser we need to add it as a script in a html file. Instead of doing it manually, we'll take the help of html-webpack-plugin.

Let’s say you use Webpack HtmlWebpackPlugin to produce a static HTML file from a template you have, but sometimes that’s not enough. This page that you’re producing is that main static page for your SPA (Single Page Application) and aside from the processed bundles, versioning etc. you would like it to have other runtime data that concerns your entire site, for instance some sort of a configuration (not secret, god forbids) that needs to be available for scripts on the client.

If you are using webpack you can use the meta option from the HtmlWebpackPlugin to add the social meta meta tags to your web page:

Injecting those script tags is normally done via https://github.com/jantimon/html-webpack-plugin

Look at the html-webpack-plugin. (https://github.com/jantimon/html-webpack-plugin#options) I think you need to manualy injects tags by setting inject to false and using htmlWebpackPlugin.files directly in your HTML template.

There are lots of options available with this plugin which you can check here.

Make sure Webpack is in production mode on release! Webpack applies a number of optimizations to your bundle, including minification with TerserWebpackPlugin if you’re using Webpack v4 or above. If not, you’ll have to install and add it manually. Other optimizations include omitting development-only code and using optimized assets.
