I built my own template engine for learning purposes with zero dependencies in TypeScript - It's called Ash

import { TemplateEngine } from '../../src';
import { dataNested } from '../shared';

const template =
  'This {{ dataNested.category }} has {{ dataNested.specs.engine.type }} with {{ dataNested.specs.engine.hp }} horsepower, and {{ dataNested.specs.doors }} doors.';

  const templateEngine = TemplateEngine.createWithMustacheSyntax();

const result = templateEngine.compile(template, { dataNested });

console.log(result);
