Installation

npm install js-utilities-libs

Usage

String Manipulation

import { trim, toCamelCase, toSnakeCase, contains } from "js-utilities-libs";

console.log(trim("  example  ")); // Output: 'example'
console.log(toCamelCase("hello_world")); // Output: 'helloWorld'
console.log(toSnakeCase("helloWorld")); // Output: 'hello_world'
console.log(contains("example", "amp")); // Output: false

Array Operations

import {
  sortArray,
  filterEvenNumbers,
  mapToUppercase,
  sumArray,
} from "js-utilities-libs";

console.log(sortArray([3, 1, 5, 2, 4])); // Output: [1, 2, 3, 4, 5]
console.log(filterEvenNumbers([1, 2, 3, 4, 5])); // Output: [2, 4]
console.log(mapToUppercase(["hello", "world"])); // Output: ['HELLO', 'WORLD']
console.log(sumArray([1, 2, 3, 4, 5])); // Output: 15

Date and Time

import { formatDate, dateDiffInDays } from "js-utilities-libs";

const today = new Date();
const tomorrow = new Date(today);
tomorrow.setDate(today.getDate() + 1);

console.log(formatDate(today)); // Output: 'YYYY-MM-DD'
console.log(dateDiffInDays(today, tomorrow)); // Output: 1

Math Functions

import { getRandomNumber, calculateAverage } from "js-utilities-libs";

console.log(getRandomNumber(1, 10)); // Output: Random number between 1 and 10
console.log(calculateAverage([1, 2, 3, 4, 5])); // Output: 3

Object Manipulation

import { mergeObjects, cloneObject, hasProperty } from "js-utilities-libs";

const obj1 = { a: 1 };
const obj2 = { b: 2 };

console.log(mergeObjects(obj1, obj2)); // Output: { a: 1, b: 2 }
console.log(cloneObject(obj1)); // Output: { a: 1 }
console.log(hasProperty(obj1, "a")); // Output: true

Validation

import { validateEmail, validateURL } from "js-utilities-libs";

console.log(validateEmail("[e-mail]")); // Output: true
console.log(validateURL("https://example.com")); // Output: true

File and Path Operations

import { readFile, writeFile } from "js-utilities-libs";

readFile("example.txt")
  .then((data) => {
    console.log(data); // Output: Contents of the file
  })
  .catch((err) => {
    console.error(err);
  });

writeFile("example.txt", "Hello, world!")
  .then(() => {
    console.log("File written successfully!");
  })
  .catch((err) => {
    console.error(err);
  });

Network Utilities

import { fetchData } from "js-utilities-libs";

fetchData("https://jsonplaceholder.typicode.com/posts/1")
  .then((data) => {
    console.log(data); // Output: JSON data from the API
  })
  .catch((err) => {
    console.error(err);
  });

Data Formatting

import { objectToJson, jsonToObject } from "js-utilities-libs";

const obj = { key: "value" };
const jsonString = objectToJson(obj);

console.log(jsonString); // Output: '{"key":"value"}'
console.log(jsonToObject(jsonString)); // Output: { key: 'value' }

Error Handling

import { logError, formatErrorMessage } from "js-utilities-libs";

try {
  // Code that may throw an error
  throw new Error("An error occurred");
} catch (error) {
  logError(error); // Output: [timestamp] Error: An error occurred
  console.log(formatErrorMessage(error)); // Output: An error occurred: An error occurred
