Generate Snowflake and Unique IDs

1. Create an instance of the ID class with a machine ID

   const idGenerator = new ID(1);

   // Generate a Snowflake ID
   const snowflakeID = idGenerator.getSnowflakeID();
   console.log(`Snowflake ID: ${snowflakeID}`);

   // Generate a Unique ID
   const uniqueID = idGenerator.getUniqueID();
   console.log(`Unique ID: ${uniqueID}`);

   const serial_number = idGenerator.generateSerialNumber({
     format: "XXXXXX",
   });
   
   console.log(`Serial Number: ${serial_number}`);

File upload

1. Local server.

   // Uploads a file to the local server.
   const uploadedFileUrl = await FileUploadToLocalServer({
     req,
     pathToUpload,
     imageKeyWord,
   });

   // Deletes a file located at the specified path.
   DeleteLocalServerFile(filePathToDelete);

2. S3 Spaces

   // Allowed file extensions for upload
   const allowedExtensions = [".jpg", ".png", ".jpeg"];
   
   // Upload the file to the specified bucket
   const uploadedFileKey = await FileUploadToSpacesBucket({
     req,
     pathToUpload,
     imageKeyWord,
     fileTypes: allowedExtensions,
   });

   // Attempt to delete the file
   const isDeleted = await DeleteFileSpacesBucket(fileKey);

Removes the specified text from the array.

const array = ["hello", "world", "hello"];
const result = array.removeText("hello");
console.log(result); // Output: ['world']

Verify the Integrity of Color Hash Codes

1. Checks if the given string represents a valid hexadecimal color code.

   "#123".cIsValidColorCode(); // true
   "#12345".cIsValidColorCode(); // false
   "red".cIsValidColorCode(); // false

Handle string-based URL manipulation.

1. Parses the query parameters from a given URL string and returns them as a Map.

   const urlString = "https://example.com/path?name=John&age=30";
   const queryParams = cGetQueryParams(urlString);
   console.log(queryParams.get("name")); // Output: 'John'
   console.log(queryParams.get("age")); // Output: '30'

2. Validates a URL string.

   const isValid = cIsValidUrl("https://www.example.com");
   console.log(isValid); // Output: true

3. The cUpdateQueryParam function is an extension of the global String object in TypeScript. It provides a method for updating or adding query parameters to a URL string. This can be especially useful in web development when you need to modify URLs dynamically.

   // Original URL
   const originalUrl = "https://example.com/page?name=John";
   
   // Updated URL with a new query parameter or modified existing parameter
   const updatedUrl = originalUrl.cUpdateQueryParam("age", "30");
   
   console.log(updatedUrl);
   // Output: 'https://example.com/page?name=John&age=30'

Example Usage of Utility Functions

1. Define a sample Express route handler

   const sampleRouteHandler = (req: Request, res: Response) => {
     try {
       // Construct a JSON response using the `toJson` function
       toJson(res, {
         data: responseData, // Sample data to be included in the response
         message: "Sample response for README",
       });
     } catch (error) {
       // Handle errors and construct an error response using the `errorResponse` function
       errorResponse(res, error);
     }
   };

2. Check if a value has data

   const hasValue = hasData("Sample Data"); // true if the value is not empty

3. Check if a date is valid

   const isDateValid = isValidDate("2023-09-07"); // true if the date is valid

4. Check if a date and time is valid

   const isDateTimeValid = isValidDateTime("2023-09-07 14:30:00"); // true if the date and time are valid

5. Add one day to a date

   const newDate = adjustDateByDays(new Date("2023-09-07"));

6. Get an image URL with a placeholder if no data is available

   const imageUrl = getImg("https://example.com/image.jpg"); // Provided URL if data exists, otherwise a placeholder URL

7. Compare two JSON objects for deep equality

   const obj1 = { key1: "value1", key2: { nestedKey: "nestedValue" } };
   const obj2 = { key1: "value1", key2: { nestedKey: "nestedValue" } };
   
   const areEqual = compareJSONObjects(obj1, obj2); // true if objects are deeply equal

8. Convert a number to a string or empty string if it's zero

   const stringValue = convertNumberToStringOrEmpty(0); // "" (empty string)

Converts a JSON string to a JavaScript object.

const jsonData = '{"name": "John", "age": 30}';
const jsonObject = cToJson(jsonData);
console.log(jsonObject); // Output: { name: 'John', age: 30 }

const data = { name: "Alice", age: 25 };
const convertedData = cToJson(data);
console.log(convertedData); // Output: { name: 'Alice', age: 25 }

const invalidData = "not a valid JSON";
try {
  const result = cToJson(invalidData); // Throws an error
} catch (error) {
  console.error(error.message); // Output: "The data cannot be converted into a JSON format."
}

Filters the input list to keep only the unique objects.

cGetUniqueObjects()

// Example Usage
const inputList = [
  { id: 1, name: "Alice" },
  { id: 2, name: "Bob" },
  { id: 1, name: "Alice" }, // Duplicate object
];

const uniqueObjects = cGetUniqueObjects(inputList);
console.log(uniqueObjects);
