What is dot?
The 'dot' npm package is a fast and lightweight template engine in JavaScript. It allows you to create dynamic HTML templates with embedded JavaScript logic. It is known for its simplicity and performance, making it suitable for both client-side and server-side rendering.
What are dot's main functionalities?
Basic Template Rendering
This feature allows you to create a basic template and render it with dynamic data. The template string contains placeholders that are replaced with actual data when the template is rendered.
const doT = require('dot');
const template = doT.template('Hello, {{=it.name}}!');
const result = template({ name: 'World' });
console.log(result); // Output: Hello, World!
Conditional Rendering
This feature allows you to include conditional logic within your templates. The template string can contain conditional statements that control whether certain parts of the template are rendered.
const doT = require('dot');
const template = doT.template('{{? it.show }}Hello, {{=it.name}}!{{?}}');
const result = template({ show: true, name: 'World' });
console.log(result); // Output: Hello, World!
Looping
This feature allows you to loop over arrays within your templates. The template string can contain loop statements that iterate over arrays and render each item.
const doT = require('dot');
const template = doT.template('{{~it.items :item:index}}<li>{{=item}}</li>{{~}}');
const result = template({ items: ['Item 1', 'Item 2', 'Item 3'] });
console.log(result); // Output: <li>Item 1</li><li>Item 2</li><li>Item 3</li>
