Introduction to Addon Tools

Addon Tools is a comprehensive library designed to simplify and enhance your development process. It offers a range of utility and helper functions across various domains, making it easier to build robust applications. Below, we’ll dive into dozens of useful API explanations, complete with code snippets and an app example demonstrating their application.

String Manipulation APIs

capitalizeFirstLetter

Capitalizes the first letter of a given string.

  function capitalizeFirstLetter(str) {
    return str.charAt(0).toUpperCase() + str.slice(1);
  }
  console.log(capitalizeFirstLetter("hello")); // Output: Hello

reverseString

Reverses a string.

  function reverseString(str) {
    return str.split('').reverse().join('');
  }
  console.log(reverseString("hello")); // Output: olleh

Array Manipulation APIs

deepCloneArray

Creates a deep clone of an array.

  function deepCloneArray(arr) {
    return JSON.parse(JSON.stringify(arr));
  }
  const arr = [1, 2, 3];
  const clone = deepCloneArray(arr);
  console.log(clone); // Output: [1, 2, 3]

findMax

Finds the maximum number in an array.

  function findMax(arr) {
    return Math.max(...arr);
  }
  console.log(findMax([1, 2, 3, 4, 5])); // Output: 5

Date APIs

formatDate

Formats a date into ‘yyyy-mm-dd’ format.

  function formatDate(date) {
    let d = new Date(date),
        month = '' + (d.getMonth() + 1),
        day = '' + d.getDate(),
        year = d.getFullYear();

    if (month.length < 2) month = '0' + month;
    if (day.length < 2) day = '0' + day;

    return [year, month, day].join('-');
  }
  console.log(formatDate(new Date())); // Output: 2023-10-03 (or current date)

daysDiff

Calculates the number of days between two dates.

  function daysDiff(date1, date2) {
    const oneDay = 24 * 60 * 60 * 1000; // hours*minutes*seconds*milliseconds
    return Math.round(Math.abs((date1 - date2) / oneDay));
  }
  console.log(daysDiff(new Date('2023-01-01'), new Date('2023-01-10'))); // Output: 9

App Example Using Addon Tools

Let's create a simple app that greets the user with a formatted date and performs some string and array manipulations.

  // Import Addon Tools APIs (assuming they're in `addon-tools.js`)
  import { capitalizeFirstLetter, reverseString, deepCloneArray, findMax, formatDate, daysDiff } from './addon-tools';

  // App implementation
  const user = {
    name: "john doe",
    dates: ["2023-01-01", "2023-10-03"]
  };

  // Greet user
  const greetUser = (user) => {
    const formattedName = capitalizeFirstLetter(user.name);
    const today = new Date();
    const formattedDate = formatDate(today);
    return `Hello, ${formattedName}! Today's date is ${formattedDate}.`;
  };

  // Perform string manipulations
  const manipulationExample = (str) => {
    const reversed = reverseString(str);
    return `Original: ${str}, Reversed: ${reversed}`;
  };

  // Perform array manipulations
  const arrayExample = (arr) => {
    const clonedArray = deepCloneArray(arr);
    const maxNumber = findMax(arr);
    return `Cloned Array: ${clonedArray}, Max Number: ${maxNumber}`;
  };

  console.log(greetUser(user)); // Output: Hello, John doe! Today's date is 2023-10-03.
  console.log(manipulationExample("addon-tools")); // Output: Original: addon-tools, Reversed: sloot-nodda
  console.log(arrayExample([1, 2, 3, 4, 5])); // Output: Cloned Array: 1,2,3,4,5, Max Number: 5

By leveraging the addon-tools library, you can create versatile applications with ease. Try integrating these APIs into your projects to see the difference!
