What is string-template?
The string-template npm package allows you to easily create and manipulate string templates. It provides a simple way to replace placeholders in a string with actual values, making it useful for generating dynamic content.
What are string-template's main functionalities?
Basic Template Replacement
This feature allows you to replace placeholders in a string with corresponding values from an object. In this example, the placeholder {name} is replaced with 'World'.
const template = require('string-template');
const result = template('Hello, {name}!', { name: 'World' });
console.log(result); // Output: Hello, World!
Multiple Placeholders
You can use multiple placeholders in a single string and replace them with values from an object. This example replaces {firstName} and {lastName} with 'John' and 'Doe' respectively.
const template = require('string-template');
const result = template('Hello, {firstName} {lastName}!', { firstName: 'John', lastName: 'Doe' });
console.log(result); // Output: Hello, John Doe!
Nested Object Replacement
The package supports nested object replacement, allowing you to access properties within nested objects. In this example, {user.name} is replaced with 'Alice'.
const template = require('string-template');
const result = template('Hello, {user.name}!', { user: { name: 'Alice' } });
console.log(result); // Output: Hello, Alice!
