Solved: html-webpack-plug

Writing a very long article about html-webpack-plugin involves quite a bit of technical information, but I’ll do my best to break it down in a step-by-step manner.

The HTML webpack plugin simplifies the creation of HTML files to serve your webpack bundles. This is especially useful for webpack bundles that include a hash in the filename which changes every compilation. You can let the plugin generate an HTML file for you, have it interpolate the hashes for you, and profit.

Now let’s get into the solution to a common problem you might encounter when using the HTML webpack plugin.

Common Problem

Let’s say you want to inject scripts into the body or head of the HTML. This includes all chunks by default – not what we want.

Solution to the problem

Here’s a fundamental misassumption that only head and body tags can be used for injection. We can have more options by setting the inject option in the HTML webpack plugin configuration.

Now let’s dive into some JavaScript coding to illustrate this in a more practical manner.

new HtmlWebpackPlugin({
  inject: 'body',
  // Other configurations...

This is one way to do it. You can also inject the script into the head like so:

new HtmlWebpackPlugin({
  inject: 'head',
  // Other configurations...

Step-By-Step Explanation of Code

1. ‘inject: body’ This inserts the generated js files into the bottom of the body tag in this particular case we ensure that all files are loaded when we want to start using them.
2. ‘inject: head’ This means that the script will be placed in the head of the HTML.

In other cases, these options may not be enough. For instance, if we have several entry points and want to place different scripts in different places.

Sure, here is the structure of the article.

Testing is an integral part of any software development process. It is how you ensure that the code you write does what it was intended to do and how you catch any bugs that may have slipped in. One common way of reporting on how much of your code is reached by your tests is through test coverage reports. In JavaScript, one popular testing framework that provides functionality to generate coverage reports is Jest. Running ‘test:coverage’ command in Jest will provide a detailed test coverage.
