YA Handlebars Bundler is a command-line interface (CLI) tool designed as a lightweight, standalone alternative to complex build tools like Webpack or Gulp for compiling Handlebars.js templates, partials, and helpers. The current stable version is 2.1.3. It operates by watching specified directories for changes, caching files in RAM, and recompiling only affected assets into a single JavaScript bundle. Key differentiators include its zero-setup nature, ability to monitor dynamically created files, and output bundles compatible with CommonJS (Node.js, Browserify), AMD (RequireJS), and direct browser inclusion without custom loaders. The tool also supports minification and mangling of the output, making it suitable for both development and production environments. It focuses on providing a streamlined templating workflow without the overhead of a full-fledged module bundler. The release cadence appears to be feature-driven rather than time-boxed, providing stability for users.

Verified usage

ya-handlebars-bundler is primarily a command-line interface tool. It is installed globally or locally and invoked via its CLI commands, not directly imported into JavaScript code. The generated bundle is then consumed.
npm install -g ya-handlebars-bundler
handlebars-init
handlebars-watch
After the generated `handlebars.bundle.js` is loaded (via `require` or `<script>`), it populates the global or imported `Handlebars` object. Templates are then accessed through `Handlebars.templates` (or `Handlebars.partials`). Ensure the `handlebars` library is loaded *before* the bundle in browsers.
const Handlebars = require('handlebars');
require('./handlebars.bundle.js');
const html = Handlebars.templates.myTemplate({});
Similar to templates, partials are exposed on the `Handlebars` object. The bundle automatically registers partials under their respective paths (e.g., `nes/ted/kitty` for `~/myapp/partials/nes/ted/kitty.hbs`). The main `Handlebars` library must be present first.
const Handlebars = require('handlebars');
require('./handlebars.bundle.js');
const partialHtml = Handlebars.partials['my/nested/partial']({});
This quickstart guides through global installation, project initialization with default configuration, continuous bundling, and how to consume the generated Handlebars bundle in a Node.js environment.
/* Install globally */
npm install -g ya-handlebars-bundler
/* Create a new project directory */
mkdir my-handlebars-app
cd my-handlebars-app
/* Initialize default configuration and example files */

// filename: 'handlebars.bundle.js',
// minify: false,
// },
// options: {
// verbose: true,

/* Start the bundler in watch mode (run as background task in production) */

/* In your Node.js application (e.g., app.js) */
// First, install the handlebars runtime library
// npm install --save handlebars
const Handlebars = require('handlebars');
// Load the generated bundle. This will populate Handlebars.templates and Handlebars.partials.
require('./handlebars.bundle.js');
// Assuming you have a template named 'kittens.hbs' in your 'templates' directory,
// and a partial 'nes/ted/kitty.hbs' in your 'partials' directory.
const templateData = { message: 'Hello from Handlebars!' };
const kittenHtml = Handlebars.templates.kittens(templateData);
const nestedPartialHtml = Handlebars.partials['nes/ted/kitty'](templateData);
console.log('Kitten Template Output:', kittenHtml);
console.log('Nested Partial Output:', nestedPartialHtml);
// Example of using a custom helper (assuming 'capitalize' helper is defined in helpers/capitalize.js)
// Handlebars.registerHelper('capitalize', (context, options) => { /* ... */ });
// const capitalizedMessage = Handlebars.helpers.capitalize('my message'); // Direct helper call
