Eta | Eta

A faster, more lightweight, and more configurable EJS alternative

Eta vs. EJS:

Eta supports Deno, out-of-the-box
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>

<%= await getSomeValue() %>
    
<% /* Eta supports multiline comments,
which is really useful */ %>

<%= "<%" %>

<% /* Embedded JS templates mean that you can
write any valid JS expression inside interpolate tags: */ %>

<%= 2 + 4 %>

<%~ include("mypartial") %>

<%~ include('./navbar', { pages: [
  'home',
  'about',
  'users'
] }) %>

<% layout("layouts/basic") %>

<p>This will be rendered into a layout</p>
