arc-templates
Fully powered ES6 JavaScript template engine with halfway-decent syntax.
There are two "builds" available: a Node.js 4+ version with minimal Babel transpiling, and an ES5 version with full Babel transpiling. The unit tests are run on both new and older Node versions.
Simple example
Templates can use expressions:
Hello, ${ name }{ name: 'world' } will result in:
Hello, worldLoops
JavaScript blocks with nested document blocks allow a natural expression of loops:
<% for (let item of items) { <:<div>${item}</div>:> } %>Layouts
Templates can define layouts for a "template of the template":
<! layout.html !><div>body</div>layout.html contains:
<html><head></head><body><**></body></html><html><head></head><body><div>body</div></body></html>head and body in an HTML document.
Partials
Templates can also include other templates in their output:
before <( include.html )> afterinclude.html contains:
