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