Vento Template Fragments

A plugin for Vento that allows you to render out small portions of a template. Useful for hypermedia-oriented front-end libraries like htmx.

This implementation is based on htmx's template fragments essay.

Installation

import fragments from "https://deno.land/x/vento_plugin_fragments@0.1.0/mod.ts"

env.use(fragments());

npm install vento-plugin-fragments

Then simply import the plugin.

import fragments from "vento-plugin-fragments";

env.use(fragments());

Add {{ fragment }} tags to mark sections of the template you want to render individually:

<html>
    {{ fragment list }}
        {{ for user in users }}
            <li>{{ user }}</li>
        {{ /for }}
    {{ /fragment }}
</html>

Then use the # query parameter to render out the fragment:

const users = ["Jared", "Kim", "Bob"];

const fragment = await env.run("template.vto#list", { users }).content;

Which renders only the fragment:

<li>Jared</li>
<li>Kim</li>
<li>Bob</li>
