tempura

Features

* Extremely lightweight

_Everything is 1.26 kB (gzip) – even less with tree-shaking!_

* Super Performant

_Significantly faster than the big names; and the small ones._

* Familiar Syntax

_Tempura templates look great with Handlebars syntax highlighting._

* Custom Directives

_Easily define custom blocks, via the API, to extend functionality._

Install

``
$ npm install --save tempura
`

Usage

`hbs
{{! expected props to receive }}
{{#expect title, items }}

{{! inline variables }}
{{#var count = items.length }}
{{#var suffix = count === 1 ? 'task' : 'tasks' }}

{{#if count == 0}}

`js

const template = await readFile('example.hbs', 'utf8');

// Transform the template into a function
// NOTE: Produces a string; ideal for build/bundlers

let toESM = transform(template);
console.log(typeof toESM); //=> "string"
console.log(toESM);
//=> import{esc as $$1}from"tempura";export default function($$3,$$2){...}
