Introduction

The Supercharge frameworks ships with built-in support for view rendering using Handebars templates. Also, Supercharge provides you a handful of convenient helpers which are automatically registered when starting your application. You can use all helpers in your Handlebars templates without extra configuration.

JSON

In some situations, you may want to pass a JSON string your views. To convert a JavaScript object to a JSON data structure, use the {{json}} helper:

<script>
    const json = {{json data}}
</script>

The {{json}} helper creates a minified JSON string by default. If you need a pretty printed JSON string with line breaks and two spaces indention, pass the pretty=true attribute to the helper:

<script>
    const json = {{json data pretty=true}}
</script>

Raw Templates

In situations where you don’t want Handlebars to render your template, you can use the {{#raw}} block helper. This helper deactivates Handlebars template rendering and any interpolation.

<div>
    {{#raw}}
        <vuejs-component></vuejs-component>
    {{/raw}}
</div>

A raw template may be helpful when using Handlebars in combination with Vue.js or any other frontend framework.

CSRF Field

Every time you’re adding a form in your application, you should add a CSRF token. This CSRF token can then be validated by the CSRF protection middleware. In your forms, add a hidden CSRF form field using the {{csrf}} helper:

<form method="POST">
    {{csrf}}

    …
</form>

CSRF Token

For siutations where you only need the CSRF token and not a hidden form field, you may use the {{csrfToken}} helper. This helpers returns the plain CSRF token value:

<form method="POST">
    <input type="hidden" name="yourCsrfFieldName" value="{{csrfToken}}">

    …
</form>
