  <h2>
   Key Concepts, Techniques, and Tools
  </h2>
  <h3>
   Task Runner: The Foundation
  </h3>
  <p>
   A task runner is a software application that automates repetitive tasks, typically associated with software development. Common tasks include:
  </p>
  <ul>
   <li>
    Running unit tests
   </li>
   <li>
    Building and compiling code
   </li>
   <li>
    Linting and code formatting
   </li>
   <li>
    Deploying applications
   </li>
   <li>
    Managing dependencies
   </li>
  </ul>
  <p>
   Task runners enhance developer productivity by freeing up time from manual processes, enabling developers to focus on core development activities.
  </p>
  <h3>
   Node.js Version Management: A Crucial Aspect
  </h3>
  <p>
   Node.js, the JavaScript runtime environment, undergoes frequent updates with new features and bug fixes. Project dependencies might rely on specific Node.js versions, leading to compatibility issues when using an incompatible Node.js version. Node version management tools provide a way to isolate project-specific Node.js environments, ensuring consistent behavior across development, testing, and production.
  </p>
  <h3>
   Shuru: The Simplified Task Runner
  </h3>
  <p>
   Shuru emerges as a user-friendly task runner with built-in Node.js version management. It leverages Node.js's built-in package manager (npm) to define and manage tasks within a project. Shuru's simplicity and efficiency make it an excellent choice for both individual developers and teams working on JavaScript and TypeScript projects.

  <h2>
   Step-by-Step Guide: Getting Started with Shuru
  </h2>
  <h3>
   1. Installation
  </h3>
  <p>
   Start by installing Shuru globally on your system using npm:
  </p>

bash
npm install -g shuru

  <h3>
   2. Project Setup
  </h3>
  <p>
   Create a new project directory and initialize it with npm:
  </p>

bash
mkdir my-project
cd my-project
npm init -y

  <h3>
   3. Shuru Configuration
  </h3>
  <p>
   Create a `shuru.config.js` file in your project root to configure Shuru:
  </p>

javascript
module.exports = {
tasks: {
build: {
command: 'tsc',
nodeVersion: '16.x', // Specify the Node.js version for this task
},
test: {
command: 'jest',
nodeVersion: '14.x', // Specify the Node.js version for this task
},
},
};

  <p>
   In this configuration, we define two tasks: "build" and "test". The "command" property specifies the command to execute for each task. The "nodeVersion" property sets the Node.js version to use for that specific task.
  </p>
  <h3>
   4. Running Tasks
  </h3>
  <p>
   Run Shuru tasks from the command line using the following syntax:
  </p>

bash
shuru build
shuru test

  <p>
   Shuru will automatically manage the Node.js version specified in the configuration and execute the task.
  </p>
  <h3>
   5. Custom Tasks
  </h3>
  <p>
   You can define custom tasks by adding them to the "tasks" object in `shuru.config.js`. These custom tasks can include any shell command you need to execute.
  </p>

javascript
module.exports = {
tasks: {
// Existing tasks...
lint: {
command: 'eslint src',
nodeVersion: '18.x', // Specify the Node.js version for this task
},
},
};

  <h3>
   6. Advanced Configuration
  </h3>
  <p>
   Shuru offers advanced configuration options for customizing its behavior, including:
  </p>
  <ul>
   <li>
    <strong>
     Task Dependencies:
    </strong>
    Define task dependencies to ensure tasks run in the correct order.
   </li>
   <li>
    <strong>
     Parallel Execution:
    </strong>
    Run tasks concurrently for improved performance.
   </li>
   <li>
    <strong>
     Custom Scripting:
    </strong>
    Use JavaScript functions within the configuration to create complex tasks.
   </li>
  </ul>
