1. Introduction

Brief Explanation of the Tutorial's Goal

This tutorial aims to guide you through the process of creating a workflow for HTML development. The goal is to streamline your development process, making it more efficient and effective.

What the User Will Learn

By the end of this tutorial, you will be able to create an HTML development workflow. You will understand how to structure your projects, manage dependencies, automate tasks, and test your code.

Prerequisites

Before starting this tutorial, you should have a basic understanding of HTML and CSS. Familiarity with JavaScript and command line/terminal is a plus but not necessary.

2. Step-by-Step Guide

Project Structure

The first step in creating an effective workflow is to set up a consistent project structure. This means organizing your files and directories in a way that makes sense and is easy to navigate.

/my-project
  /css
  /js
  /img
  index.html

This is a simple structure for an HTML project, with separate directories for CSS, JavaScript, and images.

Dependency Management

Dependency management is crucial in any development workflow. A tool like NPM (Node Package Manager) can help manage your project's dependencies.

npm init

This command creates a package.json file in your project directory, which keeps track of all your project's dependencies.

Task Automation

Gulp is a task runner that can be used to automate repetitive tasks like minification, compilation, unit testing, and linting.

npm install --global gulp-cli

This command installs Gulp globally on your machine.

Testing

Testing ensures your code works as expected. A tool like Jest can help with this.

npm install --save-dev jest

This command installs Jest as a dev dependency for your project.

3. Code Examples

Project Structure

Here is a simple example of a project structure:

/my-project
  /css
    style.css
  /js
    script.js
  /img
    logo.png
  index.html

This structure keeps your stylesheets, JavaScript files, and images in separate directories.

Dependency Management

The package.json file created by the npm init command might look like this:

{
  "name": "my-project",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

This file keeps track of your project's metadata and dependencies.

Task Automation

A basic gulpfile.js for task automation might look like this:

const gulp = require('gulp');

gulp.task('hello', function(done) {
  console.log('Hello, World!');
  done();
});

Running gulp hello in your terminal would output "Hello, World!".

Testing

A simple test with Jest might look like this:

test('adds 1 + 2 to equal 3', () => {
  expect(1 + 2).toBe(3);
});

Running npm test in your terminal would run this test.

4. Summary

In this tutorial, we covered how to create an HTML development workflow, including setting up a project structure, managing dependencies with NPM, automating tasks with Gulp, and testing your code with Jest.

5. Practice Exercises

1. Set up a new HTML project with a similar structure to the one we used in this tutorial.
2. Install a new NPM package and add it to your package.json file.
3. Write a Gulp task to minify your CSS files.
4. Write a Jest test for a simple JavaScript function.

Remember, practice is key when learning new concepts. Keep experimenting with different tools and techniques to find what works best for you.
