Eta | Eta

A faster, more lightweight, and more configurable EJS alternative

Eta vs. EJS:

Eta's more lightweight, weighing in at only 2.4KB gzipped
Eta supports Deno, out-of-the-box
Eta's much faster at compiling and rendering than EJS. Check out these benchmarks
Eta supports layouts out of the box (learn more)
Eta allows left whitespace control (with -), something that doesn't work in EJS because EJS uses - on the left side to indicate that the value shouldn't be escaped. Instead, Eta uses ~ to output a raw value
Eta gives you more flexibility with delimeters -- you could set them to {{ and }}, for example, while with EJS this isn't possible
Eta adds plugin support
Comments in Eta use /* ... */ which allows multiline commenting and is more consistent
Eta doesn't break with delimiters inside strings and comments. Example: <%= "%>" %> works in Eta, while it breaks in EJS
Eta exposes Typescript types and distributes a UMD build
Eta allows custom tag-type prefixes. Example: you could change <%= to <%*
Eta throws more informative errors. If you accidentally leave a tag, string, or multiline comment unclosed, Eta will tell you where the problem is

Users:
<ul>
<% it.users.forEach(function(user){ %>
  <li><%= user %></li>
<% }) %>
</ul>

Unbeatable Performance

Benchmarks demonstrate just how fast Eta is. Think fast, then multiply by crazy speedy, and you have an idea of Eta's performance.

Simply JavaScript

Eta's template syntax (inspired by EJS) means you write templates with just JavaScript -- you don't have to learn an entirely new template syntax.

Powerful and Lightweight

Eta was designed by the team who created Squirrelly, as an alternative to EJS. Though it has almost-compatible syntax to EJS, it's more configurable and has a minzipped bundle cost of only ~2KB!

Configurable and pluggable

Eta supports plugins, custom delimiters, caching, and so much more!
