simple-string-truncate

simple-string-truncate is a lightweight utility for truncating strings in JavaScript. It allows you to dynamically set a length limit and append a custom truncation symbol (e.g., ...) when the string exceeds the specified limit. This package handles various edge cases, ensuring robust performance.

Features

• Dynamic Truncation: Set custom length limits and truncation symbols.
• Edge Case Handling: Gracefully handles non-string inputs, short strings, and invalid truncation limits.
• Lightweight: Minimalistic and efficient, perfect for small to mid-sized projects.

Installation

You can install simple-string-truncate via npm:

npm install simple-string-truncate

Usage

Here’s a simple example of how to use simple-string-truncate:

const truncateString = require('simple-string-truncate');

const longString = 'This is a long string that needs to be truncated';
const shortString = 'Short string';

console.log(truncateString(longString, 20)); // Output: 'This is a long str...'
console.log(truncateString(shortString, 20)); // Output: 'Short string'

Parameters

-- str (string) : The string to be truncated. -- limit (number, optional) : The maximum length of the string before truncation. Default is 50. -- symbol (string, optional) : The symbol to append to the truncated string. Default is ....

Edge Cases

Non-string input : Throws an error. Empty string : Returns an empty string. limit less than the length of symbol : Throws an error. Strings shorter than or equal to limit : Returns the original string without modification.

Example

// Truncate with a custom limit and symbol
const customTruncate = truncateString('Truncate me!', 8, '---');
console.log(customTruncate); // Output: 'Trunca---'

// Handle edge cases
try {
    truncateString(12345, 5); // Non-string input
} catch (error) {
    console.error(error.message); // Output: 'Input must be a string'
}
