-
Extremely lightweight
Everything is1.22 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.
$ npm install --save tempura
