@push.rocks/smarthbs

handlebars with better fs support

Install

To install @push.rocks/smarthbs, run the following command in your terminal:

npm install @push.rocks/smarthbs --save

This will add @push.rocks/smarthbs to your project's dependencies.

Usage

The @push.rocks/smarthbs package enhances Handlebars with improved filesystem support, making it easy to manage partials and compile directories with template files. Below is a comprehensive guide to utilizing its capabilities in your project.

Getting Started

First, ensure you've imported @push.rocks/smarthbs using ECMAScript Module (ESM) syntax in TypeScript:

import * as smarthbs from '@push.rocks/smarthbs';

Registering Partials

In Handlebars, partials are reusable templates that can be included within other templates. @push.rocks/smarthbs simplifies the process of registering all partials from a directory, enabling a more organized template structure.

To register all .hbs files from a directory (and its subdirectories) as partials:

await smarthbs.registerPartialDir(pathToPartialsDirectory);

Example:

await smarthbs.registerPartialDir('./views/partials');

This automatically registers each .hbs file in the directory as a partial that can be referenced by its path relative to the specified directory.

Compiling Templates

@push.rocks/smarthbs allows you to compile an entire directory of Handlebars template files, outputting the rendered HTML to a specified directory. You can also provide a .json file containing data to be used by all templates during compilation.

Example:

await smarthbs.compileDirectory(sourceDirectory, destinationDirectory, 'data.json');

This reads all .hbs files in sourceDirectory, compiles them using the data from data.json, and writes the resulting HTML to destinationDirectory.

Finding Variables in Templates

When working with complex templates, it might be useful to programmatically find all variables used within a template:

let varsInTemplate = await smarthbs.findVarsInHbsString(templateString);
console.log(varsInTemplate); // Outputs an array of variable names used in the template

Checking Variables Satisfaction

To ensure that the data provided to a template includes all necessary variables, you can compare a template against a data object:

let missingVars = await smarthbs.checkVarsSatisfaction(templateString, dataObject);
if(missingVars.length > 0) {
  console.error('Some required variables are missing:', missingVars);
}

This function returns an array of missing variable names, allowing you to validate data completeness before rendering.

Templates and Strings

You can also get templates directly from strings or files on disk, which can then be rendered with context data:

// From a string
let templateFromString = await smarthbs.getTemplateForString("Hello {{name}}!");
let resultString = templateFromString({ name: "World" });
console.log(resultString); // Outputs: Hello World!

// From a file
let templateFromFile = await smarthbs.getTemplateForFile("./templates/greeting.hbs");
let resultFileString = templateFromFile({ name: "File World" });
console.log(resultFileString); // Outputs the rendered content of greeting.hbs with provided data

Post-processing: Safe Syntax

In scenarios where Handlebars syntax needs to be preserved during an intermediate step:

let safeString = await smarthbs.postprocess(yourTemplateString);

This method converts safe syntax markers (e.g., {-{ and }-}) back into standard Handlebars syntax ({{ and }}), useful if your templates go through multiple processing steps.

Advanced Usage and Helpers

@push.rocks/smarthbs also supports advanced use cases and custom helpers. For example, registering a helper to log all available partials or to perform runtime template compilation based on dynamic data.

Conclusion

@push.rocks/smarthbs provides a robust set of features to enhance your Handlebars templating, making it easier to manage and render complex templates with external data sources and organized partials. Whether you're building web applications, generating email templates, or any task involving templating, @push.rocks/smarthbs can simplify and streamline your workflow.
