@rn-common/string-util

This module provides utilities for generating universally unique identifiers (UUIDs) and formatting strings with placeholders using the Expo Crypto library.

Installation

Install using:

npx expo install @rn-common/string-util expo-crypto

Utilities

uuid()

Generates a universally unique identifier (UUID). This function utilizes Crypto.randomUUID() to produce a UUID, a standardized 128-bit identifier commonly used for uniquely identifying information in computing systems.

Returns

• string: A string representation of the generated UUID.

Example

import { uuid } from '@rn-common/string-util'

const id = uuid()
console.log(`Generated UUID: ${id}`)

formatTemplate(template: string, args: Record<string, any>)

Formats a string by replacing placeholders with corresponding values from an arguments object. Placeholders in the string should be enclosed in double curly braces (e.g., {{key}}), where key corresponds to a property name in the args object. The function replaces these placeholders with their respective values from args.

Parameters

• template (string): The string containing placeholders to be replaced.
• args (Record<string, any>): An object containing key-value pairs where keys correspond to placeholders in the text and values are the replacement values.

Returns

• string: The formatted string with placeholders replaced by their corresponding values from args.

Example

import { formatTemplate } from '@rn-common/string-util'

const template = 'Hello, {{name}}! Welcome to {{place}}.'
const values = { name: 'Alice', place: 'Wonderland' }
const result = formatTemplate(template, values)
console.log(result) // "Hello, Alice! Welcome to Wonderland."
