SpaceCat Shared Utilities

This repository contains a collection of shared utility functions used across various SpaceCat projects. These utilities provide a range of checks and validations, from basic data type validation to more complex checks like ISO date strings and URL validation.

Installation

To install the SpaceCat Shared Utilities, you can use npm:

npm install spacecat-shared-utils

Or, if you are using yarn:

yarn add spacecat-shared-utils

Usage

Here's how you can use the different utility functions in your project:

import { isBoolean, isValidUrl } from 'spacecat-shared-utils';

console.log(isBoolean('true')); // true
console.log(isValidUrl('https://www.example.com')); // true

Functions

The library includes the following utility functions:

• isBoolean(value): Determines if the given value is a boolean or a string representation of a boolean.
• isInteger(value): Checks if the given value is an integer.
• isValidDate(obj): Checks whether the given object is a valid JavaScript Date.
• isIsoDate(str): Validates whether the given string is a JavaScript ISO date string in Zulu (UTC) timezone.
• isIsoTimeOffsetsDate(str): Validates whether the given string is a JavaScript ISO date string following UTC time offsets format.
• isNumber(value): Determines if the given value is a number.
• isObject(obj): Checks if the given parameter is an object and not an array or null.
• isString(str): Determines if the given parameter is a string.
• toBoolean(value): Converts a given value to a boolean. Throws an error if the value is not a boolean.
• arrayEquals(a, b): Compares two arrays for equality.
• isValidUrl(urlString): Validates whether the given string is a valid URL with http or https protocol.
• hasText(str): Checks if the given string is not empty.
• dateAfterDays(number): Calculates the date after a specified number of days from the current date.

SQS Event Adapter

The library also includes an SQS event adapter to convert an SQS record into a function parameter. This is useful when working with AWS Lambda functions that are triggered by an SQS event. Usage:

import { sqsEventAdapter } from '@adobe/spacecat-shared-utils';

// ...

export const main = wrap(run)
  .with(dataAccess)
  .with(sqsEventAdapter) // Add this line
  .with(sqs)
  .with(secrets)
  .with(helixStatus);

Testing

This library includes a comprehensive test suite to ensure the reliability of the utility functions. To run the tests, use the following command:

npm test
