🌳 balsa

Balsa is a delightfully simple HTML template engine. It is designed to be used in user interfaces such as a CMS where a user needs to be able to edit the template's parameters. Therefore, Balsa includes support for extra metadata, such as friendly variable names, default values, and types.

What does it look like?

<h1>
  {{ headerText, type: string, friendlyName: "Header text", defaultValue: "Hello
  world!" }}
h1>

Here, we define a new variable called headerText, which is a string with a default value of "Hello world!". We also gave it a friendly name, which can later be resolved and shown to a user in a control panel, etc. We can even define variables inside the template like so:

{{@ defaultHeader = "Hello world!" }}

<h1>
  {{ headerText, type: string, friendlyName: "Header text", defaultValue:
  $defaultHeader }}
h1>
<h2>The default header value is: {{ $defaultHeader }}h2>
