What is HTML Pug? Core Concept

Pug is an HTML preprocessor that allows developers to utilize indentation to signify layering and structure instead of typical HTML syntax. Pug is an open-source program accessible under the MIT license that can be used with most current web development frameworks. This is what is Pug.

Pug Benefits

Pug simplifies coding by letting developers utilize indentation to express layering and structure, making the code more straightforward and understandable. This results in shorter development times and a lower risk of code problems.

Pug also utilizes Variables and mixins across the project. Changes may be done in a single spot rather than throughout the source, making it easier to manage and update the codebase.

Another advantage of Pug is its ability to ease the building of complicated HTML structures, like forms and tables, through reduced syntax. This can help developers new to the project or unfamiliar with typical HTML markup comprehend the codebase.

How to Use Pug in Web Development? 

Follow these steps to utilize Pug in web development:

Step 1: Install Pug

If you are using Node.js and npm, open your terminal and run the following command:

npm install Pug

Step 2: Set up your project

  1. Make a new folder for your project and browse it in your terminal.
  2. Make a new file with the ‘.pug’ extension. This file will contain your Pug code.
  3. Create a simple HTML file that will be the entry point for your Pug templates. For example, create an `index.html` file and include the following code:
<title>My Pug Website</title>
<!– Pug templates will be rendered here –>

Step 3: Write Pug templates

  1. Open your ‘.pug’ file and begin typing the Pug code.
  2. Pug uses indentation to determine the structure of your HTML markup. Make sure you indent your code correctly.
  3. You can build succinct and tidy HTML code using Pug’s syntax. Instead of ‘div>,’ you might type ‘div.’
  4. Pug, among other things, provides variables, conditionals, loops, and includes, which may make your templates more dynamic and reusable.

Step 4: Compile Pug templates

  1. It would help to compile your Pug templates before converting them to HTML. You can accomplish this using either a build tool or the Pug CLI.
  2. Using a build tool like Gulp or Webpack, you may create a building job to assemble your Pug files.
  3. To compile your Pug file into HTML using the Pug CLI, open your terminal, browse your project folder, and enter the following command:

npx pug <file-name>.pug –output <output-directory>

Replace `<file-name>.pug` with the name of your Pug file and `<output-directory>` with the directory where you want the compiled HTML file to be saved.

Step 5: Include the compiled HTML

  1. Once you convert the Pug templates into HTML, you may use a script tag or a suitable technique provided by your web framework to include them in your ‘index.html’ file (or any other HTML file).
  2. For example, if you compiled your Pug file and saved it as ‘index.html,’ you may include it in your ‘index.html’ file by using the following code:
<title>My Pug Website</title>
<!– Include the compiled HTML –>
<script src=”index.html”>

Step 6: Serve your website

  1. You may now serve your website via a web server or access your browser’s ‘index.html’ file.
  2. If you don’t open the produced HTML files directly, configure your web server to serve them.

That’s all! Pug has now been installed and utilized in your web development project. Pug’s solid capabilities and succinct syntax might assist you in writing more clean and manageable HTML code. So this is all about what HTML Pug is.
